The maintenance and upkeep of gantry cranes during use is an important part. Below, Shandong gantry crane manufacturer will teach you how to properly maintain them.

1、 Lubrication

The working performance and service life of various mechanisms of a crane largely depend on lubrication. When lubricating, the maintenance and lubrication of mechanical and electrical products should refer to their own instructions. Large vehicles such as traveling carts and overhead cranes should be lubricated once a week. When adding industrial gear oil (SY1172-80) 200 to the winch, the oil level should be checked regularly and replenished in a timely manner.

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 must 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、 Brake system

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.
