Trouble shooting Hand Hydraulic Truck

COMMON FAILURES AND SOLUTIONS OF MANUAL HYDRAULIC TRUCKS.

Most users in the use of manual hydraulic trucks due to the normal operating procedures do not pay attention to the failure of the pallet truck, but do not know what causes, we know the pallet truck forks do not rise for the reasons will be timely in the emergence of the problem will be dealt with, manual hydraulic truck in the entire handling process plays an irreplaceable role, so in the use of the process must pay attention to maintenance, so that we can make The following are common failures and solutions of manual hydraulic trucks.

    1.MANUAL HYDRAULIC TRUCK FORKS CAN NOT FALL

    Reason analysis: the pressure prevention valve is not adjusted, the position of the piston rod of the cylinder offset, due to offset load and cause parts damage or deformation

    Solution: Drop the correct anti-pressure valve, replace the piston rod or cylinder, repair or replace the relevant parts

    2.WHEN THERE IS NO PRESSURE RELEASE, THE FORK SLIPS

    Reason analysis: air in the hydraulic oil, impurities in the hydraulic oil, the anti-pressure valve is not adjusted, the seal is broken

    Solution: Exclude air, replace the clean hydraulic oil, adjust the pressure prevention valve, replace the new seals

    3.THE TRUCK FORKS DO NOT RISE 

    Cause analysis: impurities in the hydraulic oil, pressure release valve is not adjusted, the hydraulic oil has air 

    Solution: Replace the clean hydraulic oil, adjust the pressure release valve, and exclude the air in the oil pump 

    4.THE TRUCK OIL LEAKAGE

    Cause analysis: the seals are worn or damaged, parts cracked or worn

    Solution: Replace the new seals, and check and update parts

   5.THE LIFTING WEIGHT DOES NOT MEET THE STANDARD

    Reason: impurities in the hydraulic pressure, the use of one-way valve can not be closed

    Solution: Replace the pure hydraulic oil

    6.CRAWLING WHEN NO LOAD

    Reason analysis: the door clamp deformation, cylinder seals screwed too tight, so that the plunger rod resistance is too large

    Solution: correction of the door frame or mediation roller shaft adjustable screws, adjust the cylinder upper port nut

    7.LIFT SLOWLY OR CRAWL

    Cause analysis: the hydraulic system strictly punish leakage, seal aging or damage, there is air in the hydraulic system

    Solution: Fasten the adjustable screw for oil release and replace the seal ring to remove the air

IN ORDER TO EXTEND THE SERVICE LIFE OF THE EQUIPMENT, WE HAVE TO DO THE FOLLOWING.

    1.Manual hydraulic Stacker should be used in hard and flat road, to prevent and steel plate, angle and other damage to the wheel substance collision, no need to hit the pile with the fork, in the process of lifting the goods, the nearby can not stand people, maintenance and adjustment should be done after the goods down.

    2.In the use of hydraulic Stacker truck in other occasions or conditions of operation, be careful operation, correct operation, to ensure the safety of the operation.

    3.Manual hydraulic Stacker truck troubleshooting related to the Stacker truck can continue to operate the conditions, often learn the common troubleshooting method of manual hydraulic stacker truck.

    4.The equipment should be used before the car has the necessary inspection and maintenance, focusing on checking the wheels and arbor, door clamp guide theory, joint screws and bearing position can be flexible rotation, timely cleaning and refill lubricating oil.

    5.The fork of the stacker should not carry people, fork under the fork is prohibited to stand people, handling process, fork height from the ground can not be higher than 300mm, the goods should be placed between the amount of fork, do not single fork force, strict control of the position of the center of gravity of the goods.
