Hydraulic lift maintenance methods: First, hydraulic lift maintenance time requirements: 1, routine maintenance (each class). 2 lift work 1500 hours, the mechanical, electrical systems for minor repairs. 3. Lift 5000 hours after work on the mechanical and electrical systems for repair. 4. Lifts work 10,000 hours, mechanical, electrical systems overhaul. Second, the hydraulic lift mechanical equipment maintenance and maintenance: 1 agencies of the brake 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 thinner. 2. Gearbox, gearbox, external gear and other parts of the lubrication and hydraulic oil are in accordance with the requirements of the lubrication table. 3 should pay attention to check the ministries have broken wire and loose stock phenomenon. If more than the relevant provisions must be immediately renewed. Wire rope maintenance should be strictly in accordance with the provisions of GB5144-85. 4. Always check the connection of the ministries, if loose should be tightened. The body connecting bolts should be checked when the body pressure tightness (rotating arm can be used to cause compression), all connected to the shaft must have a cotter pin, and to be fully open. 5. Often check whether the normal operation of various agencies, with or without noise, if found fault, must be promptly excluded. 6. When installing, disassembling and adjusting the slewing mechanism, pay attention to ensure that the center line of the slewing gear reducer is parallel to the centerline of the gear. Its mating surface is not less than 70% and the meshing clearance is suitable. 7. Always check all the wires, cables for damage. To promptly dressing and replacement to damage the part. 8. Encountered a motor overheating phenomenon to stop in time, troubleshooting and then continue to run, the motor bearing lubrication to be good. 9. All parts of the brush, the contact surface to be clean, adjust the brush pressure, the contact area of ​​not less than 50%. 10. Control boxes, distribution boxes and other regular clean, timely cleaning of electrical equipment dust.
