Scissor Pallet Truck so as not to affect the normal operation of the hydraulic system.

Manual hydraulic pallet trucks, also known as manual forklift to load when using fork inserted into the tray hole driven by a hydraulic system to achieve human cargo tray lifting and lowering, pulling completed by human handling operations. It is the most convenient means Electric lifters of transport pallets, most effective, the most common loading and unloading, handling tools.
1, should be based on different environments, use different operating oil. When the ambient temperature is -5 ~ +45' C, please use the mirror synthetic oil, add the oil must be clean, so as not to affect the normal operation of the hydraulic system.
2, the structure of the ministries should be checked before use is normal, all joints is loose.
3, the goods should be uniformly electric pallet trucks distributed in the surface of the fork not tilt or a single crossed up, after the accident to prevent tipping or goods damaged parts.
4, after the operation, should be unloaded and placed in a low position of the car, will not allow heavy objects on a long fork.
5, during transport van, probably due to inversion causes the hydraulic system into the air, resulting in a slow lifting rod or pressure is less than the job requirements. Under no circumstances should the load, put the car in a low position, but pulled grapple, reciprocating several times to return to normal.

Scissor Pallet Truck Wear a gap between the stem and the body is too large

Manual Forklift  Stacker due to long-term use or distribution valve dirty oil to speed up the stem and the body, such as wear and tear, with the destruction of the sealing surface, causing oil spills. If the repair stem wear lighter, can stem polished chrome; If the stem badly worn, replace
2, leakage between the valve body
electric reach stackers cylinder seal failure, resulting in leakage; valve performance when installing injury or aging or damaged O-rings in the hydraulic effect, but also prone to leakage between the valve body.
If you need to be polished valve damage, replace the O-ring, according to the order and tighten the bolt torque requirements.
3, the valve spring failure
If the valve spring failure, hand pallet trucks oil under pressure can be forced below the system requirement to leave the ball spill valve inflow tract, causing the leak, the system failure.
Spring must be replaced when the manager, and then use the adjustment screw to adjust the spring pressure 14 Mpa regulations. On demand from the load center at 600mm load adjustment 7.5t goods when the goods like starting with a non-locking nut from the lock, then the pressure is the need to adjust the pressure.

the control part - used to control and regulate the oil pressure, flow and flow direction.

Hand Pallet Truck with oil as the working medium , to pass the motion by changing the volume of the seal to transmit power through the oil pressure inside .

1, the dynamic part - the original motivation of the mechanical energy is converted to oil pressure energy .

2 , the operative part - the oil pressure pump input energy into mechanical energy to drive the work of agencies.

3, the control part - used to control and regulate the oil pressure, flow and flow direction.

4 , the auxiliary section - the first electric pallet jacks three parts are connected together to form a system from oil storage , filtering , measuring and sealing effect.

Pressure in a volume of liquid at any point on the applied equal size can be transmitted to all directions. This means that when using a plurality of hydraulic cylinders , each of the speed of each cylinder will be pulled or pushed , the speed of which depends at electric pallet jack the pressure required to move the load .

At the same carrying capacity of the hydraulic cylinder , the hydraulic cylinder bearing the minimum load will be moved first , the maximum load bearing end of the cylinder to move .

To synchronize the movement of the hydraulic cylinder , the load at any point in order to achieve the same speed is lifting, be sure to use a control valve in the system or synchronous lifting system components.

liftstar drum truck After a comprehensive assessment of the impact to the above aspects

different models in different market holdings , its after-sales support capabilities are different, for example : low driving three high stacking forklift driver and three belong to the narrow channel stacking forklift truck series , can be in a very narrow channel ( 1.5 ~ 2.0 m ) to complete palletizing , pick up . But the former scissor pallet truck can not raise the cab , so poor operating perspective, the lower the efficiency . Since the latter can be completely covered by the former features, and performance is more superior, and therefore beyond 4 to 5 times the sales in the European market, the latter than the former , in China reached more than 6 times . Therefore, most of the suppliers are focused to develop three high stacking forklift driver , while the low three- stacking manual stacker   driver is only used in small -tonnage , low lift height ( generally less than 6 meters ) of operating conditions . In the small market sales , the number of its service engineers , engineers experience, service capabilities , such as parts inventory levels will be relatively weak.

After a comprehensive assessment of the impact to the above aspects , choose the most reasonable option.

Air scissor lift Passed open the door to global markets

Passed open the door to global markets , on the one hand to the Chinese system operated pallet trucks and pallet trucks wholesale industry provides a steady stream of orders, vast space , but it is also for the industry and the promotion of quality wholesale pallet trucks , learn techniques to improve their predecessors level created  Air scissor lift opportunities . Various types of connections MEIDE forging , pipe scissor pallet truck fittings, has been formed in the UK , U.S. and Germany large scale 3 Series 5 more than a thousand varieties, annual production capacity of over 200,000 tons sold in more than 100 countries and regions worldwide , becoming the world's the largest and most complete product regulation , market share has the highest rate , the overall strength of the strongest manufacturers producing malleable iron pipe fittings . After entering the new century , Lu Chu , chairman of its proposed change to the family wholesale pallet trucks pallet power pallet jack trucks wholesale family .
  In metallurgy, pallet trucks , chemical, power and other key industries as well as industrial parks and  Air scissor lift a number of cities to carry out a pilot recycling economy , improve laws and regulations , the development of an effective model to explore the economic cycle . France, Germany , Britain and other countries have to adopt international standards as a trump card to enter the international market , the Nordic countries are almost without any modification directly using the international scale as the market entry criteria , the U.S. position on the use of international standards is also turned positive by the cold even the love of developing countries are increasingly high international standards
