When using a crane, attention should also be paid to its maintenance. What are the precautions for maintaining a crane? If you also want to know, let the Shandong gantry crane manufacturer introduce it to us.

1. Lubrication

The working performance and service life of various mechanisms of a crane largely depend on lubrication, which is an important part of the maintenance and upkeep of the equipment. The quality of lubrication directly affects the operation and service life of each mechanism, as well as production and efficiency. Therefore, operators and maintenance personnel should regularly check the lubrication condition of the lubrication points of this equipment, and replenish and replace lubricants on time.

The principles to be followed for lubrication and maintenance: Regular lubrication should be applied to all parts where there is a dynamic fit between the shaft and the hole, as well as to mechanical parts with friction surfaces. Due to the different operating conditions (such as usage rate and environment) of the crane, the lubrication of different parts should be appropriately controlled according to the specific situation.

2. Steel wire rope

Attention should be paid to the situation of wire rope breakage. If there are broken wires, broken strands, or wear reaching the scrap standard, new ropes should be replaced in a timely manner. Steel wire ropes that can be selected include phosphated coated steel wire ropes, galvanized steel wire ropes, and smooth steel wire ropes.

3. Lifting equipment

The lifting equipment should be inspected regularly.

4. Pulley system

The main inspection is to check the wear of the rope groove, whether the wheel rim is cracked, and whether the pulley is stuck on the shaft.

5. Wheels

Regularly inspect the wheel rim and tread, and replace the wheel with a new one when the wear or cracking of the wheel rim reaches 10% thickness.

When the diameter difference between the two driving wheels on the tread exceeds D/600, or when there are serious scratches on the tread, it should be re polished.

6. Brakes

Each class should be checked once.

The brake should act accurately and the pin shaft should not be stuck. The brake shoes should fit the brake wheels correctly, and the gap between the brake shoes should be equal when releasing the brake.
