Mechanical grab

Grab mechanical structure itself is not configured to open and close, usually driven by a rope or rod force, operating characteristics can be divided by double rope grab and single-rope grab, the most commonly used is the double rope grab.
Two rope grab opening and closing of supporting rope rope around the supporting bodies, respectively opening and closing mechanism of the roll. Figure 1 is a double rope grab the working process: a support rope and rope while opening and closing down, open the mouth into the bucket stockpile. b is the tightening of the opening and closing rope grab jaws closed and materials. c is the support rope grab is closed and the opening and closing rope simultaneously rise. d is the support rope does not move, opening and closing abseiling, bucket mouth open and remove the materials. Double rope grab, electrics tacker  easy to operate, high productivity, widely used. Using two sets of double rope after a four rope grab, work processes and the same double rope grab.
Support single rope grab ropes and opening and closing with a rope with a rope. The rope through a special locking device for opening and closing alternately supportive role. Grab the single rope winding mechanism is relatively simple, but the production is low, a large number of loading and unloading operations rarely used.
Grab crawled under the bulk density of the material is divided into light (such as crawling cereals), medium (such as crawling grit) and heavy (such as crawl iron ore) Class 3; divided by the number of double jaw jaw grab and multi-jaw grab, the most commonly used is a double jaw grab. For the bulk ore, iron and steel scrap, and should adopt more jaw grab, because it has more than claws, sharp cut features, easy to insert stockpile, can get better crawl results. There is also a structural principle of imitation scissors scissor grab, grab it with the force and energy of the closed jaws gradually increases, reaches a maximum in the closed end; their bucket mouth opening and the area of cover material than generally grab for the big, improved ability to crawl, help clean the yard and cabins, but for bulk materials because of its initial gripping force is small, less effective.

Grab crane classification

Grab bucket by about two or more combinations of jaw opening and closing crawl and unloading bulk material spreader, composed of a plurality of jaw gripper grab is also called.

Classified by shape
Can be divided according to the shape and orange petal shell-shaped grab grab, the former consists of two full buckets, the latter having three or more of the jaw plates.
Classification by drive
Press the drive can be divided into mechanical and hydraulic grab grab two categories.
A hydraulic grab
Hand pallet jacks grab itself with the opening and closing structure, generally with hydraulic cylinders driven by a plurality of hydraulic jaw plates, also called hydraulic claw grab. Hydraulic grab the hydraulic class-specific equipment used widely, such as hydraulic excavators, hydraulic lifting tower.
Hydraulic grab products are hydraulic structures, by a hydraulic cylinder, bucket (jaw), connecting column, bucket ear plate, earmuffs bucket, bucket teeth, adapters and other parts composition, so welding is the most critical hydraulic grab production process, welding quality directly affects the structural strength and hydraulic grab life. Another hydraulic cylinder is the most critical drive components.
Hydraulic grab is a special industry equipment, accessories, need special equipment to high-efficiency, high-quality work performed, such as: CNC plasma cutting machine, beveling edge milling machine, bending machine, welding positioner machine, boring machine, hydraulic test stand, etc. .
Special hydraulic excavator grab divided into two kinds of rotating and non-rotating, do not turn back to grab excavator bucket cylinder oil used without addition of hydraulic valve block and piping; grab to be added back to the turn of the a hydraulic valve block and piping to control.
Special hydraulic excavator grab applicable occasions:
1, building foundation pit excavation pit excavation and mud, sand, coal, gravel loading.
2, is particularly suitable for trench or the side of the restricted space excavation and loading.
3, for ships, trains, car handling.

wind cable rope initial tension

powered palle ttruck is not working when the mast rope cable pre-tension force of the wind. Rally Rally beginning to take work for 15% -20%.
2 wind cable pulling rope work
Work force is at work mast cranes, wind cable rope assumed loads.
In the right wind cable wire process layout, there is always a wind cable hoisting rope is determined by the vertical axis and the mast vertical plane, this root wind cable wire called the "main wind cable rope."
3 wind cable rope selected basic principles: all wind cable wire rope shall be selected according to the main wind cable.
Selection for wind cable wire to the main cable tension and wind the rope work and as the basis of the initial tension.
(Three) types of anchors, anchor calculations
Type: Full buried, half buried, activity type and use of buildings
1 full Buried ground anchors can withstand greater tension, suitable for heavy lifting. Calculate the intensity normally be based on soil conditions and checking its horizontal beam material stability, vertical stability and beam intensity.
2 movable anchor to withstand the force is not suitable for renovation and expansion project. Calculate the strength necessary to calculate the horizontal and vertical stability stability

Herringbone pull lever pull lever forward tilt when lifting

Herringbone pull rod
Herringbone pull rod is normally provided by two logs or two steel wire rope lashing or iron pieces hinged together. The advantage is that the lateral stability than the one-man pull rod is good, the use of a small number of wind cable rope, but the component after lifting a small range of activities. Herringbone pull rod bottom with rod or rope to balance the horizontal thrust, two angle is generally about 30 °. Herringbone pull lever pull lever forward tilt when lifting, there are two wind cable in the back rope. To ensure that when lifting the bottom of the pull rod firmly, pull the lever in a bottom mounted a guide pulley, lifting cable connected to the winch through it, and then the other on a rope connected to the anchor.
Roundwood herringbone pull rods, from the weight of 40 ~ 140kN, pull rod length 6 ~ 13m, roundwood small diameter 200 ~ 340mm; steel herringbone pull rods, from the weight of 100kN, pull rod length 20m, pipe diameter 273mm, wall thickness 10mm; starting weight 200kN, pull rod length 16.7m, pipe diameter 325mm, thickness 10mm.
(Three) cantilever pull rod
Pull lever arm pull rod in the middle-man or 2/3 of the height of the boom from a device. It is characterized by a lifting height and lifting larger radius, boom scissor pallet truck angle is also large. But this crane lifting capacity is small, light elements used for lifting. Boom can be mounted on the derrick, derrick pulling a lever.
Edit this paragraph mast crane is required to use non-standard cranes, generally used by the site constraints, the other can not be lifting cranes occasions.
(A) the basic structure of the mast crane and classification
Mast crane structures: the mast body, lifting systems, stability systems, power systems
Mast Body: mast base and accessories.
Mast form of the structure is divided into lattice and solid abdominal (usually steel) cranes.
Lifting system consists of pulleys, steering wheel and rope and other components.

Introduction Mast Crane
Mast Crane ----- fixed mounted cranes, generally used for port terminal mast crane, also known as pull rod or the rod, is the most simple lifting equipment. General use wood or steel Hand pallet jacks  Such cranes with making simple, easy assembly and disassembly, lifting capacity, limited by the characteristics of small construction site. Especially large components but the lack of large lifting crane, the type of lifting equipment even more its superiority. But such cranes need to set up more wind cable rope, difficult to move. In addition, the lifting radius, poor flexibility. Thus, mast cranes generally used for heavier elements, hoisting more concentrated, narrow construction site, but the lack of other suitable when large lifting machinery.
Edit this paragraph structure (a) one-man pull rod
SOLOS pull rod is divided into: Wood-man pull rod, steel rods and pull one-man one-man pull rod lattice.
SOLOS pull rod by pulling rods, lifting pulley, winch, anchor rope and wind cable and other components. Number of wind cable wire which is generally 6 to 12, at least not less than 4. Lifting the pull bar holding not more than 10 °, inclination. Striga pull lever is moved by its bottom skid proceed. (One-man pull rod erected)
Wood-man pull rod from the weight in less than 100kN, lifting height is 8 ~ 15m; steel pull rod weight of up to one-man 300kN, lifting height of 20m or less; lattice-man pull rod weight of up to 1000kN , lifting height of up to 70m.

Bridge crane trolley gear due to vibration

Bridge crane trolley gear due to vibration, abrasion, pressure, temperature and other factors, the combination of surface sealing parts often appear static leakage. Traditional treatment methods to remove reducer, replacing gaskets or sealant applied, but time-consuming and difficult to ensure the sealing effect, will appear again in the operation of leakage. Contemporary Western countries use more polymer composites leakage field of governance, the most widely Blessed World Blue series. Polymer-free disassembly repair and materials have excellent adhesion, oil resistance and 350% elongation, good to overcome the impact of vibration reducer, repair effect is more effective than traditional methods.
Wear governance
Bridge crane initiative running gear wheels and carts frequently repeated electrics tacker stop and parking will cause reverse gear torque of each axis, vibration increases, could easily lead to leakage. Such problems occur, the traditional method and more to be machined after welding or repair the main brush, but there are some drawbacks both: high thermal stress generated by welding can not be completely eliminated, prone to bend or break; the brush plated by the coating thickness limit is easily peeled off, and the above two methods are metal with metal repair, you can not change the "hard to hard" with the relationship, the combined effect of the force, will cause wear again. New repair method mostly polymer composites based, and the application of more surgery products, which has superior adhesion, excellent compressive strength and other performance. Applied Polymer repaired, neither welding thermal stress on the repair thickness is not restricted, while products with metallic materials do not have the concession, can absorb shock and vibration equipment, to avoid the possibility of re-wear and greatly extended equipment component life, save a lot of down time, creating significant economic value.

mast mast bottom should be compacted bottom handle, smooth, spread over two sleepers

Bridge crane within the plant, because the top rail from the roof chord close, plus overhead cranes are larger in size and weight, it is not mechanized lifting. SMEs often use a single mast crane lifting the overall standing, so you can improve efficiency, shorten the construction period and reduce high-altitude operations, the construction procedure is as follows.
(A) the erection of the mast
① mast mast height maximum height of the ground to the roof top of the mast to a height less operating space between the roof and the height of the mast sleepers inquiry. Minimum height should meet the needs of lifting height.
② mast mast position due to be erected in the carts between the two main beam bridge crane center of gravity, the car must be biased, but the mast should deviate from the centerline of plant, shown in Figure 7-8. Its offset should be based on weight carts, trolleys and trolley weight offset distance determined by calculation.
③ mast mast bottom should be compacted bottom handle, smooth, spread over two sleepers, if necessary, can be added between two sleepers rails or beams, paved area determined by calculating base endurance, ensure that the ground bear mast axial pressure.
④ mast mast electric stacker methods used mobile cranes erect, quick and safe crane beam can also be used stand mast bracket wrench can also be used auxiliary mast vertical mast. Using the crane beam corbel Erecting the mast, to carry on the crane beam corbel force checking to ensure the transverse horizontal component does not exceed the maximum weight within the span of the bridge crane nominal weight and the amount of the sum of a trolley / 20.
Erection of masts, the mast should be pre-wind cable rope bindings temporarily close the roof truss bottom chords on the mast until the mast was hanging to determine the location immediately after the entire wind cable rope fastened on top of the mast and tighten the ground, such as individual wind cable rope lift after the force has stayed truss chord or circumstances, the application temporarily wind cable hove live mast, fixed wind cable rope adjusted to the appropriate location, and then release the temporary wind cable wire.

Shopping malls increased demand weakness, occupational decompose further increase competition has become even more intense, as construction machinery industry is an important part of the crane occupation facing important issues. China as the world's cranes career major malls, shopping centers toward the future, has become the focus of global corporate attention.
Qi Chun showed that although the internal electric pallet trucks Qianan, but in 2012 the mall overseas to broaden beyond nature has gained increased to hoist occupation, for example, from 2001 to 2010 this decade, employment income increased by 47.09 times, exports increased 130.05 times. Profession to the world is not only consistent, it is a common career move. Although there are still many needs of the current deal, but the results obtained are also well known, the subsequent occupation of foreign enterprises should further learning, and constantly promoted concept of operations, operational quality, skills development can, try to do better the occupation, Occupation is to promote Chinese crane hoisting mall undertaken important effort.

Technological innovation, customer needs combined with the depth of the world's resources

 Along with the domestic and foreign enterprises to carry out the process of globalization, the integration of the global market, the future is no longer bound by the state format divide, technical barriers constraints. Resolution firm location will be shopping resource companies in the world, the strategic interests of the redistribution process orientation and strategic execution.
 Current foreign companies are moving rapidly into the crane China. Liebherr early nineties in the last century have to enter the Chinese into the early twentieth century Terex, multi-country, Komatsu, the world's big-name companies are also quick squeeze Chinese crane. Manitowoc also in season this year launched a "Win in China" program. Thus, numerous giant crane strong presence in China the world.
 At the same time, Chinese companies are also moving rapidly planning global, through funding, localization serve to launch the product fit local norms, to seize the world mall. XCMG, north, Liugong, Zoomlion, welfare and other brands were digging constantly into the world market, especially XCMG truck crane last year was invented only a year of total exports 1.9 billion yuan, accounting for exports of its truck crane 65% of the total.
 Fourth, the hard power and soft power blend of depth
 Chinese crane career to complete with the world, not just relying on the crane manufacturing industry, encompassing parts production to promotion, but also downstream lifting career in the construction process technology transformation, lifting managerial innovation, and user technology, knowledge All promotions. In the first advance under the enterprise to vocational technical advancement lifting as the starting point of all femoral artery downstream industries using strength promotion, promote career advancement lifting of the air has been very dense. In this regard, XCMG after hoisting technology and promote the national contest, writing "large equipment hoisting Practical Handbook", fuck machine hand training base made the first active and fruitful quiz.
 Fifth, is the professional conduct and corporate citizenship responsibilities depth blend
 Occupation every enterprise assume this responsibility in full, regardless of Wenchuan, Yushu is still Yunnan, as well as affect the normal operation of the size of social disturbances, everywhere you can see the crane fast rescue scene. One under the crane enterprises attach importance to the expectations of elementary school, charity, Hand stacker other projects, but also to establish and carry out growth.
 I fear, the depth of integration, is becoming the most mobile cranes career milestone industrial change in the meaning.

Global mobile crane is moving toward deep blend of professional

Crane rental Hand Pallet Truck large crane lifting Jiangmen Jiangmen crane rental
European crane use common concepts depicted with scales small, light weight, small wheel pressure characteristics. Compared with conventional cranes, hook to the limit of the wall spacing minimum headroom minimum, Keli crane more jobs near the front, lifting height higher practice increases the existing plant useful work space. Because the crane is light weight, small wheel pressure characteristics, the new plant can be depicted in a smaller space, function more fully. Means the initial establishment of a smaller plant funded and long heating, air conditioning and other protective fees can save a substantial amount of money.
Usually by a crane lifting arrangement (the items up and down movement), operating arrangement (the lifting move), horn arrangements and reverse arrangement (the article for horizontal move), plus metal arrangements, power equipment, operating rigging and equipment necessary adjuvant combination. Attachment: Cranes in the study can be seen as a physical hard lever!
Bridge engineering used in lifting machinery, based on their structure and function is not the same, usually divided into small light lifting equipment, overhead type crane and jib type crane three categories. Small light lifting equipment such as: jacks, pneumatic hoists, electric hoists, balancing hoists (also known as balance suspended), winches, etc.. Girder bridge type lifting machinery such as cranes, gantry cranes. Fixed jib type crane, such as reverse cranes, tower cranes, truck cranes, truck cranes, crawler cranes. Must be promoted in the range of straight and horizontal transfer of many initiatives to lifting heavy objects. Also known as the crane. Attributed to material transfer machinery. Crane operation is characterized by intermittent exercise to do,

to enhance the user with a value as the theme of a new generation

  2010-2012, micro-economic environment remains tight, but the supply of talent added nearly twice the one hand to deal with a variety of mainstream enterprise competition pressures, but also caught with regional structural changes in the strategic plan on the end of the 2nd World of take-off, in product and technology program to quickly seize large tonnage Hand pallet jacks, Chinese enterprises once again demonstrated the advantage, one by one, "the world" is being, or is about to be born, to enhance the user with a value as the theme of a new generation technological innovation is emerging.
  2005 to 2010, showed significant changes in micro-environment: Countries increase infrastructure investment, power and other major construction projects led to the lifting process transformation, the end of this process, the three breaking mainstream enterprise: First, the world of speed, the second is the crane product structure and category further subdivided spectrum spans from 5 tons to 2,000 tons cover, vehicle type, car type, all the earth, crawler, off-road tire, etc. to get commenced; Third, large-scale. China's largest tonnage of 200 tons crane before history was broken, from the end of the world Cranes hundred-ton to kiloton crossed.

the three breaking mainstream enterprise

2005 to 2010, showed significant changes in micro-environment: Countries increase infrastructure investment, power and other major construction projects led to the Scissor lift process transformation, the end of this process, the three breaking mainstream enterprise: First, the world of speed, the second is the crane product structure and category further subdivided spectrum spans from 5 tons to 2,000 tons cover, vehicle type, car type, all the earth, crawler, off-road tire, etc. to get commenced; Third, large-scale. China's largest tonnage of 200 tons crane before history was broken, from the end of the world Cranes hundred-ton to kiloton crossedNevertheless, the authors think that the torque limiter on the mall at that time there is still a lot to improve local. Specifically there are two aspects. First, the torque limiter to improve primary element such as sensors, photoelectric encoder and line plug-ins, mostly due to one component manufacturers outsourcing, outsourcing products, because since the product quality varies greatly, simply because some shortages affecting the entire system functions . Solution to the problem is the manufacturers of the primary elements carefully selection, repeated experiments, compared to reach the optimal combination, maximum limit satisfactory system function needs; Second, some manufacturers component sensing devices depict it has not done for a long time solid, such as the appearance of the flash when testing very precise, 2-3 months after rendering errors often lead to torque limiter which the whole system failure, affecting the system robustness.

Fixed lifting platform strengths and weaknesses

   Stationary hydraulic lifting platform widely used in the transportation of goods between storey buildings, such as the workshop materials up and down the transport, storage of goods up and down conveyor can also be used for three-dimensional garage or underground garage car lift, supermarkets, hospitals, restaurants, shop goods , etc. compared with the elevator has the following useful features.
An installation location and direction of incoming and outgoing goods countertops can be more customers to choose
2 hydraulic drive with hydraulic pallet jacks machinery running smoothly variety of protective measures is simple to use security
3 can be based on user demand continues to design, capable of carrying heavy lift unachievable long wide class of goods
4 lifts its own weight down without running the motor drops can effectively reduce energy consumption to save energy
5 cost-effective than the elevator installation and maintenance simple and low failure rate

How to choose electric lift under field conditions

 In some special places, the need for electric lifts are based on the customer's load capacity, lifting height, table size, the physical environment (or hole size well and riot levels, ambient temperature, the ability to dig pits) customized. Electric lift custom-made , the general need to consider the following issues:
1 lifting platform table size in the hoistway or hole size to determine the circumstances, scissor lift platform structures do Worktable surface countertops than rail lifting platform large size, if desired table size is relatively large, the priority Select scissor lift platform.
(2) the height of the lifting platform at the height of more than 6 meters, in order to ensure the stability of the lifting platform, should be preferred rail lifting platform.
3 lifting platform site ground conditions. Scissor lift platform height than the rail itself lifting platform must be high, if the on-site underground pipes can not dig pits or trenches deeper than the height of the lifting platform itself is low, you should choose rail lift platform.
4 lifting platform electric pallet trucks, if the lifting platform is for indoor use or indoor use though, but the work site is easy to water, to ensure the safety of the lifting platform, should be preferred rail lifting platform.
5 If the lifting platform in hazardous places require a higher level, you should use explosion-proof design.
Rail lifting platform, is the use of the track chain structure, and a non-scissor lift, lifting platform rail in recent years with its unique advantages recognized by the majority of users, but under what circumstances the use rail lifting platform more convenient, cost-effective higher it?
Rail lifting platform lifting height from 4.5 m to 14 m, load from 1 ton to 10 tons limited. Rises 8 meters or less, scissor lift lifts at a lower cost than rail, generally rises 6 meters or more, can be considered the main rail lifting platform, lifting its stability, ease of operation does not lose scissor lift.
Rail lifts are generally applicable to two three-story building between the transport of goods, need to set aside a good mouth floor, especially for the need to stay between the floors of the occasion. Rail lifts for indoor jobs more, and scissor lifts are more suitable for outdoor operation.
In the choice of which lifts the structure, we need to understand the specific application areas, lift height, load, table size, lifting height is low, or load the table in ten tons or above, or a larger (15 square meters or more) is generally used Scissor lifts, otherwise use rail lift.
Jinan Huize machinery specialized production rail lifts, scissor lifts, if you are in any doubt in this regard, I can let Huize sales engineer for you to develop the best solution.

Hand Pallet Truck Note the use of which

Hand stacker in the usual life, to people's lives is a big help, the selection of quality truck carrying a lot of items that can help, but we use it for hand truck use what precautions? is not very clear for everyone here explain in detail.
First, professionals, hand truck when in use, capable of carrying the weight of the items have a certain standard, do not exceed this weight, otherwise, more prone to danger, while for the fork tool, must be insert All goods below, and then placed in a uniform slowly forks, when in use, remember to pick a single fork tips cargo.
Secondly, the manual handling car starts, to a smooth start-up, after turning in a smooth, if driving on relatively smooth pavement, wet pavement, or after, then, we should be slow down.
Furthermore, the manual handling car in the face of the ramp, when to pay attention, be careful driving, otherwise, it is easy to cause accidents.
Hand truck operation, although relatively safe, but when traveling, or need to pay attention to the pedestrian street, not because the car lost control and hazardous manual handling, hand truck when in use, is to load material, not to be able to use hand truck manned.

Choose the right step to get hand truck

In the logistics company, we will see very often hand truck, it is widely applied to the warehouses, docks and some small goods distribution center. According to the use of staff to reflect, using hand truck saves manpower and financial resources to improve handling powered palle ttruck, successfully resolved the handling process problems. However, to buy a high-quality, relatively high cost of hand truck or need certain skills, once you have mastered these skills purchase then we will discover that in the purchase of other equipment when we can take advantage of such a kind purchase method.
In an optional process we definitely want quality ranked first, only hand truck's excellent quality, with the quality to speak is the most convincing. This requires us to buy hand truck time to learn more about its performance, characteristics, scope and maintenance methods and so on. While for its length, deadweight, production materials also need special attention, and sometimes it is because we ignore some point has caused incalculable consequences.
In addition, as a wise consumer will not be confused by some of the colorful ads, and we try to choose when buying a number of brands, some companies do not covet relatively low price positioning spend money regret. The best way that we can understand its basic prices online and then have a choice to the store to purchase, make a rational consumer, understand these points.

How correct operation manual forklift

As the industry continues to develop, many occasions need to apply to forklift jacks products, machinery and equipment can be achieved using this cargo lift, short-distance transportation and so on. In some car handling workshop, warehouse dock will also apply to manual forklift truck products currently on the market quite a lot of different forklift products during operation there will be some differences. We often applied to Connaught forklift, so a lot of people know how to safely use Connaught forklift, today we will talk a manual forklift proper operation.
Manual forklift contains batteries, as this mobile device, battery protection must do the work, because if the battery storage capacity decreased, the truck will affect the use of time, frequent charging will affect the work efficiency, but also in the course of their work if not electricity, may also cause accidents. So be sure to pay attention to before using a forklift charged, each charging time must accurately grasp and can not be overcharged.
During operation, must pay attention to the downhill, uneven ground movement method, forklifts move short distances can be achieved in this process should try to ensure that the balance of the truck. In the downhill when we must pay attention to the truck control, in order to prevent runaway truck, you need to pay attention to the state of the truck brake control, minimizing truck bumps vibration.
In the process of moving the vehicle in strict accordance with operation, not be able to move forward, backward brake switch as turning to so easily lead to failure of the truck switch occurs. In turn, it should be carried out strictly in accordance with the procedure turn, not the easy way, companies in the truck driver training, it should enhance their safety awareness.
