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.

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.

lifting platform for the type of customers do not know much

Yesterday a client phone consultation Anhui Huize mechanical engineering installation site using lifting platform, lifting platform for the type of customers do not know much, do not know how the selection today Huize machinery used this example to introduce the project to install a the lifting platform.
Outset, mounting works mentioned here is different from the construction sites of the forklift jacks platform construction lifting platform, we are snorkels, a lifting handling equipment, mainly used to achieve cargo lifting operation. Engineering, installation is generally used with a lifting platform construction site installation operations in the cargo and personnel movements, because the site is variable, we choose the first choice when lifting platform mobile lifting platforms, mobile lifting platform of four mobile lifting platform, vehicle-mounted elevating platform, mobile aluminum lift platform.
Aluminum lift platform is mainly used in hotels, exhibition halls, airports and other high-altitude equipment maintenance and cleaning, aluminum lift platform is characterized by small size, carrying capacity is small, nice, obviously not suitable for our project to install cargo needs. Vehicle lifting platform is to Fixed lifting platform installed in the car, using the car's engine as a driving force, vehicle lifting platform moves convenient, fast and suitable for a large range of face and wide aerial products with operating range, continuous operation for a long time and other characteristics, especially suitable for field maintenance, street maintenance, etc. Moreover, because the need to purchase another vehicle lifting platform lifting platform installation vehicle, so the cost is much higher than other lifting platform.
Four mobile lifting platform equipped with four tires, traction force can move, but also manpower to implement, Applications: construction sites, factories, warehouses, grain depots, railway stations, hotels, airports, docks, gas stations, sports factory, elevated pipeline and other high-altitude equipment installation and maintenance, cleaning and so on.
Through the above TG mechanical description, we know that four mobile lifting platform is best suited for the site installation works of the lifting platform.
