Hydraulic lifts should be checked frequently
When we usually use hydraulic lifts, we must always check, maintain and maintain, so that not only can extend the service life of hydraulic lifts, but also make it work more powerful power! For example, the transmission part should be sufficient lubrication Oil, the wearing parts must always be inspected, repaired or replaced, the mechanical bolts, Hydraulic lift especially the often vibrating parts, such as slewing bearings, lifting arm connecting bolts should be checked for loose, if loose, even if tightened or replaced. Here, we first look at the provisions of the hydraulic lift maintenance time:
1, daily maintenance (each class).
2. 1500 hours after the work of the lift, the mechanical, electrical system for minor repairs.
3. 5000 hours after the work of the lift, the mechanical, electrical systems in the repair.
4. After the work of the elevator for 10,000 hours, the mechanical and electrical systems are overhauled.
Then, we talk about the hydraulic lift mechanical equipment maintenance and maintenance:
1. The brake of each body should always check and adjust the brake shoe and brake wheel clearance, to ensure flexible and reliable. In the friction surface, there should be no dirt, in case of dirt must be washed with gasoline or thinning.
2. Reducer, gearbox, Hydraulic lift external gears and other parts of the lubrication and hydraulic oil are in accordance with the requirements of the lubrication table.
3. Please pay attention to check the Department of wire rope with broken yarn and loose phenomenon. Such as more than the relevant provisions must be immediately renewed. The maintenance of wire rope should be strictly in accordance with GB5144-85 requirements.
4. Always check the connection of the ministries, if loose should be tightened. Body connection bolts should be checked when the body pressure tightness (can be used to rotate the arm to make the pressure state), all connected to the shaft must have a cotter pin, and need to open fully.
5. Always check the operation of the institutions are normal, with or without noise, such as failure, must be promptly ruled out.
6. Install, disassemble and adjust the rotary mechanism, pay attention to ensure that the center of the reducer reducer and the center line parallel to the gear center, the meshing surface of not less than 70%, meshing clearance to be suitable.
7. Always check all wires and cables for damage. Hydraulic lift To be timely bandaged and replaced with the damaged part.
8. Encounter the motor has overheated to stop in time, troubleshooting and then continue to run, the motor bearing lubrication to be good.
9. Each part of the brush, the contact surface to keep clean, adjust the brush pressure, so that the contact area of not less than 50%.
10. The control box, distribution box, etc. Hydraulic lift often keep clean, timely cleaning of electrical equipment on the dust.
11. The opening and closing of the travel switch of each safety device must be reliable, and the contact pit should be polished
