Hydraulic lift mechanical equipment maintenance rules

1. Lubrication and hydraulic oil of reducer, gearbox, outer meshing gear and other parts shall be carried out according to the requirements in the lubrication table.

2, each mechanism of the brake should often check and adjust the brake shoe and brake wheel clearance, to ensure flexibility and reliability. On the friction surface, there should be no dirt, in case of dirt must be washed with gasoline or dilute.

3, often check the connection of the hydraulic lift department, if there is loose should be tightened. The connecting bolts of the machine body should be checked for tightness when the machine body is under pressure. All connecting shafts must have split pins and should be fully opened.

4, pay attention to check each part of the wire rope has no broken wire and loose phenomenon. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance of steel wire rope should be strictly in accordance with the provisions of GB5144-85.

5. When installing, disassembling and adjusting the slewing mechanism, attention should be paid to ensuring that the center line of the slewing mechanism reducer is parallel to the center line of the gear, and the meshing surface is not less than 70%, and the meshing clearance should be suitable.

6, often check whether the operation of the institutions is normal, there is no noise, such as fault, must be eliminated in time.

7, encounter hydraulic lift motor overheating phenomenon to stop in time, troubleshooting and then continue to run, motor bearing lubrication should be good.

8. Check all wires and cables regularly for damage. Band-up and replace the damaged parts in time.

9, the control box, distribution box and so on often keep clean, timely clean the dust on the electrical equipment.

10, each part of the brush, the contact surface to keep clean, adjust the brush pressure, so that the contact area is not less than 50%.

11. The open and close contacts of the travel switch of the safety device must be reliable, and the contact arc pit should be polished in time.
