As a large-scale special mechanical equipment, cranes are operated frequently with heavy loads, and their parts are prone to wear and tear when used for a long time. In order to ensure the normal operation of the crane, we need to strengthen the maintenance of the crane during normal use. The following introduces the main maintenance items of the equipment:
1. Lubrication
The working performance and life of various crane mechanisms largely depend on lubrication. Lubrication is one of the important contents of crane maintenance. The quality of lubrication directly affects the operation of various crane mechanisms and the life of parts, as well as safety production. And production efficiency. Therefore, operators and maintenance personnel need to frequently check the lubrication conditions of the crane lubrication points, and replenish and replace the lubricant on time.
Lubrication and maintenance should follow the principle: where there is a dynamic fit of the shaft and the hole, as well as the mechanical part with the friction surface, it must be regularly lubricated. Due to the different operating conditions of the crane (utilization rate and use environment, etc.) It should be properly grasped according to the specific situation. Conan cranes have a centralized lubrication function to prevent omissions and other situations.
2. Wire rope
Pay attention to the broken wire of the wire rope. If there are broken wires, broken strands or when the amount of wear reaches the scrapping standard, new ropes should be replaced in time. The wire ropes that can be used include phosphating coated steel wire ropes, galvanized steel wire ropes and smooth steel wire ropes.
3. Spreader
Spreader needs regular inspection.
4. Pulleys
Mainly check the wear of the rope groove, whether the wheel flange is cracked and whether the pulley is stuck on the shaft.
5. Wheels
Regularly check the rim and tread surface. When the rim part is worn or cracked to 10% of its thickness, it should be replaced with a new wheel.
When the diameter of the two driving wheels on the tread differs by more than D/600, or there are serious scars on the tread, the car should be polished again.
6. Brake
Every shift should be checked once.
The brake should act accurately, and the pin should not be stuck. The brake shoe should fit the brake wheel correctly, and the brake shoe gap should be equal when the brake is released.
