Tower hoist overhaul and maintenance mechanism construction exploration and suggestions

The work content of the tower hoist overhaul

A, tower hoist machinery and equipment routine overhaul and maintenance

Check the various safety facilities of the tower hoist, if any fault is found, please make adjustment in time.

2. Do the daily cleaning work of each part of the tower crane and check whether each part of the tower crane is working normally. If a part is found to be faulty, it must be repaired in time.

3. Check frequently whether the exhaust plug on the tower crane hoist reducer is free to exhaust. If there is an obstacle, it must be removed and arranged in time.

4. Check the lubricity of the tower hoist gearbox, external meshing gears and other parts. These parts must be regularly oiled and painted according to the requirements of the use table. When replacing the oil, remove the box of iron filings and impurities, and refueling should also pay attention to the cleanliness and the amount of oil added.

5. When installing, disassembling and adjusting the slewing mechanism, pay attention to ensure that the centerline of the planetary gear reducer of the slewing mechanism is parallel to the centerline of the gear, and the meshing surface is not less than 70%, and the meshing clearance should be appropriate.

6. Check whether there are broken wires or loose wires in the wire rope of each part of the tower hoist. If the number of broken wire exceeds 5% or the diameter wear exceeds 5%, then the new wire rope should be replaced in time according to the safety standard.

7. Pay attention to check the use of the tower hoist brake. If there is any insensitive situation, please make adjustment in time.

8. Check the bolts of each connection of the tower hoist frequently. If there is any loosening or falling off, it should be reinforced and repaired in time.

9. Pay attention to the maintenance of metal structure, steel wire rope, electrical system, slewing support device and hydraulic jacking system, and do a good job of lightning grounding and zero connection protection. For does not meet the safety standards of the brake parts, hooks and coils, should be scrapped tube, pulley, wheel, etc..

Second, the construction of tower crane overhaul and maintenance institutions

To establish the tower hoist overhaul and maintenance mechanism, first of all, must develop clear provisions for the use of tower hoist, overhaul and maintenance

1. the construction team of tower hoist operating procedures must provide that personnel and machines must be equipped, the operation in the operation must be certified on time; must be in accordance with the tower hoist operating regulations and operating instructions, and must be careful, strict use of the tower hoist.

2. in the daily inspection and maintenance of the tower hoist, it is necessary to make a record of the daily inspection and maintenance and to fill in the record of the effect of the operation of the tower hoist.

3. For the problems found in the daily inspection of the tower hoist, specific analysis of specific problems can be made by simple adjustment. Operators deal with themselves. If the problem is very serious, should be promptly shut down in order to carry out maintenance, and keep the maintenance records of the tower.
