What Are The Maintenance Items Of The Crane

Mar 08, 2021

       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 equipment, we need to strengthen the maintenance of the equipment during normal use. The main maintenance items of this equipment are introduced below for everyone, let's learn together!


   1. Lubrication

The working performance and life of each mechanism of the crane largely depend on lubrication. Lubrication is one of the important contents of the equipment maintenance work. The quality of lubrication directly affects the operation of each mechanism and the life of the parts, and also affects safe production. And production efficiency. Therefore, operators and maintenance personnel must frequently check the lubrication conditions of the equipment's lubrication points, and replenish and replace lubricants 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 parts with friction surfaces, they must be regularly lubricated. Due to the different operating conditions (utilization rate and use environment, etc.) of the crane, the lubrication of different parts, It should be properly grasped according to the specific situation.

   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

  The spreader must be checked regularly.


  4. pulley block

  Mainly check the wear of the rope groove, whether the wheel flange is cracked and whether the pulley is stuck on the shaft.


   5. Wheel

   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.
