3 Ways of the Precautions for Daily Maintenance of the Warehouse Cargo Lift?

3 Ways of the Precautions for Daily Maintenance of the Warehouse Cargo Lift?

Make a multiple-choice question, please: The maintenance of our warehouse cargo lift: daily maintenance, monthly maintenance and annual maintenance?

  1. Daily maintenance.
  2. Monthly maintenance.
  3. Annual maintenance.

How do you choose? Anyway, personally, the C option should be common sense. Haha, actually not.

Correct maintenance can extend the service life of the elevator and reduce the incidence of elevator failure. Warehouse cargo lift maintenance can be roughly divided into: daily maintenance, monthly maintenance and annual maintenance.

Daily maintenance:

  1. Check whether the steel wire rope and guide wheel of the counterweight door are worn or not
  2. Check the oil pipes, joints, and cylinders for oil leakage
  3. Check whether all the travel switches are loose
  4. Jog the elevator and check for abnormal noise

Monthly maintenance:

  1. Check whether the bearing parts such as rollers and bearings are worn or not, and whether each fastener part is loose
  2. Check whether all the travel switches are in good contact
  3. Whether the oil cylinder is leaking and whether there is peeling off the plating layer
  4. Whether the operation of the overload protection device is normal
  5. Whether the circuit connection is clean, whether the connection is firm, and whether it works normally

Annual maintenance:

  1.  When the hydraulic oil rises to the highest level, is the oil level 40-50mm higher than the suction port?
  2.  Whether the hydraulic oil has deteriorated, if it deteriorates, replace the hydraulic oil in time
  3.  Clean the oil system
  4.  Check whether there are abnormal phenomena in other parts

Then let’s Follow our engineer to learn some specified examples: How to maintain the solenoid valve of the warehouse goods lift.

Speaking of solenoid valve, it is an electric switch in brief. Cargo lift that uses electromagnetic control is an automation basic component used to control fluid. It is mostly used in hydraulic systems. It is widely used in hydraulic equipment (for example: hydraulic cargo lifts, lifting platforms, lifts for the disabled Etc.). Solenoid valves can cooperate with different circuits to achieve the desired control. As the cargo lift’s solenoid is used for a long time, a layer of dirt will adhere to its surface, which affects the normal and healthy use of the lift equipment. Therefore, When using the warehouse cargo lift, the solenoid valve of the lift needs to be maintained. Then How to maintain it correctly? Please refer to the below tips:

  1. The pressure adjustment of the overflow valve does not meet the requirements Adjust the pressure to the required value
  2. Leakage in the cylinder Check or replace the cylinder assembly
  3. The reversing valve is clamped or internally leaked. Check or replace the valve assembly
  4. The oil level is too low, the oil inlet oil filter is blocked. Add enough oil and clean the oil filter
  5. The oil supply pump is faulty. Check or replace the pump

On the other hand: Unable to lift or weak rise

  1. The pressure adjustment of the overflow valve does not meet the requirements Adjust the pressure to the required value
  2. Internal leakage of the oil cylinder See the elimination method in the above item 2.3.4.5
  3. The reversing valve is clamped or internally leaked
  4. The oil level is too low, the oil inlet filter is blocked
  5. The fuel supply pump is faulty
  6. Check valve leakage Check whether the check valve core and valve seat are worn and damaged, whether the check valve spring is fatigued, deformed, etc.
