Edit:Xinertai Hydraulic MachineryUpDate:2019-09-23

Frequent necessary protection operations can reduce wear and tear, eliminate hidden dangers and failures, and insist that the equipment is always in an outstanding technical condition to extend its service life, reduce operating costs, and ensure safe and reliable operation.

Repair and maintenance content technology: including "clean, tighten, adjust, smooth" eight-character work.

Cleaning is to clean the surface, interior and circumferential surface of the brake wheel, electrical contacts, electromagnet contact surfaces and the surrounding environment of the gate hoist regularly. The doors and windows inside and outside the hoist room should be cleaned once a week, and the tools and equipment on the field should be cleaned up in time and placed neatly.

Tightening is to tighten threaded pipe joints and gland bolts for sealing in the pressure oil system to prevent loosening and cause oil leakage; for various positioning bolts, high-strength bolts, wire rope compression bolts and spreaders such as foundations and flanges Tighten the connecting bolts, if loose, it will change the force and movement of the connected parts and constitute a hidden danger of accident.


①Adjust the clearance between bearing bush and journal, rolling bearing, the top and side clearance of gear meshing, and the loose brake clearance between brake shoe and brake wheel.

②Adjust the brake release stroke, clutch clutch stroke, safety limit switch limit stroke and gate opening and closing direction indication stroke.

③ Adjust the looseness of rolling belts, chains, etc. and the elasticity of tension springs. ④Adjust current, voltage, braking torque, flow pressure and speed of hoist.

Smoothness: For the relative moving parts in the hoisting equipment, outstanding smoothness should be maintained.

Repair protection is an important part of the operation management of gate hoist. The protection of gate hoist should be based on the principle of "safety first, prevention first". It must be "always protect, repair at any time, care more than repair, repair more than grab."
