Hydraulic Lift Abnormal Problems And Maintenance Methods

With the development of industrialization, lift platform has been widely used in every corner of life. In the morning, the building near the district is under construction. A curved arm lift is busy and enters the company building. The ladders are lifted by the lift next to the elevator. The garage is standing on a self-propelled hydraulic lift. The Lift on your side for your service, we use the hydraulic lifts, often in the working state of the sudden occurrence of some unusual problems, summed up here for your reference.

Suddenly can not lift. Please check whether the hydraulic oil pipeline is normal, and whether there is a foreign body stuck in the running track, hydraulic power unit is normal, inside the closed mailbox is leaky position.

2. Suddenly the electronic control platform is not controlled. Please check whether the power supply is stable, the circuit is broken. If you check everything is normal, you should consider whether the built-in electrical accessories are damaged, because the company uses most of the electrical accessories for Chint Electric, it is recommended familiar with Chint Electric engineers or maintenance personnel to repair or replacement, the proposed power failure under the maintenance.

3. Lifting equipment work a substantial shaking, please check whether the foot movement instability, and the arm is caused by the lack of oil.

4. Multi-cylinder scissors table suddenly tilted, please check the cylinder is normal, as well as the occurrence of external bending bending stent, and need to carefully check whether the tubing foreign body blockage, resulting in non-synchronous phenomenon.

5. Maintenance method

When we usually use hydraulic lifts, we must always check, maintenance and maintenance, so that not only can extend the life of hydraulic lifts, but also make it work when the greater power of hair! For example, the transmission part should have enough oil to the parts must be frequently checked, repaired or replaced, the mechanical bolts, especially the often vibrating parts, such as slewing bearings, lifting arm connection bolts should be checked whether loose There must be loosening even if tightened or replaced.

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, 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. Wire rope maintenance 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. To be timely bandaged and replaced with the damaged part.

8. Encounter the motor has overheated to stop in time to troubleshoot 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. 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 in time.
