Common faults and solutions of stackers

Common faults and solutions of stackers

  • 2021-07-21
Common faults and solutions of electric stackers:

  ①Hydraulic oil leakage;

   Reason 1: The seal is worn or broken

  Solution: Better seals for cylinders

   Reason 2: The parts in the cylinder are worn out and cracked

  Solution: only need to replace the parts inside the cylinder,

   But changing the seal will cause air to enter the hydraulic system, we can raise and lower the fork many times, that is, we can drain the air in the hydraulic cylinder

  ②The electric pallet truck is not depressurized but the truck descends;

   Reason 1: There are impurities in the hydraulic oil, causing the pressure relief valve to fail to close

  Solution: need to replace clean hydraulic oil

   Reason 2: The pressure relief valve is not adjusted properly

  Solution: adjust the pressure relief valve

   Common faults and solutions of electric stackers:

  ①The fork cannot be raised to the highest level;

   Reason: caused by insufficient hydraulic oil

  Solution: add hydraulic oil to the cylinder

  ②The fork cannot rise or fall;

   Reason: There are impurities in the hydraulic oil,

  Solution: just change to clean hydraulic oil

  ③The fork cannot be lowered;

   Reason: The piston rod of the oil cylinder may be deformed due to eccentric load

   Solution: Replace the piston rod or directly replace the entire cylinder

   Have you learned the common faults and troubleshooting methods of electric pallet trucks/stackers?

   Know a little about the maintenance of electric forklifts, knowing that it is very important~ It doesn’t matter if you don’t understand, look for Batel forklifts!

   It is inevitable for any mechanical equipment to malfunction after long-term use. Of course, the electric stacker is no exception. So, what are the common faults in the use of electric stacker trucks? How can these faults be eliminated? I will give you a brief introduction here.

   1. The electrical system does not work

   Failure reason: poor power cord wiring or battery connector failure

   Troubleshooting: Check and correct the power wiring or replace the battery connector

   2. The pump motor does not work

   Reasons for the failure: a. Poor power cord wiring b. Burned fuse c. Pump contactor failure d. Pump motor failure

   Troubleshooting: a. Check and correct the power cord b. Replace the fuse c. Replace the pump contactor d. Check and repair the motor

   3. The battery indicator does not work

Causes of the failure: a. Poor power cord wiring b. Burned fuse c. Damaged key switch d. Damaged battery indicator Treatment method: a. Check and correct the power cord wiring b. Replace the fuse c. Replace the key switch d. Replace the electric stacker Car battery indicator

   4. Excessive noise

   Failure reasons: a. Gear or bearing damage or gear involute groove wear b. Insufficient amount of lubricating oil or oil quality

   Treatment method: a. Replace gears or bearings
b. Add or change gear oil

   5. Excessive clearance

   Failure reason: the accumulated clearance is too large (including backlash)

   Treatment method: adjust or replace

   6. Oil spill

   Failure reason: oil seal or gasket damaged

   Treatment method: replace the oil seal or gasket

  During the use of the electric stacker, the above are common faults and treatment methods.
