Lubrication precautions for bridge cranes

Lubrication is one of the important measures to ensure the normal operation of machines, extend the lifespan of machine parts, and ensure safe production. Maintenance personnel should fully understand the importance of equipment lubrication, regularly inspect the lubrication condition of each moving point, and regularly add lubricating oil (grease) to each lubrication point. Below, the manufacturer of bridge cranes in Shandong will specifically explain to you what are the precautions for lubricating bridge cranes?

Main lubrication parts

① The winch of the bridge crane; ② Various bearings; ③ Gear couplings; ④ Reducer; ⑤ Steel wire rope; ⑥ Hinge points on the brake.

Lubrication precautions

1. Keep the lubricating oil (grease) clean;

2. Lubricating oils (greases) of different grades should not be mixed for use;

3. Select appropriate lubricating oil (grease) and lubricate according to the specified time;

4. Use the pressure greasing method (with an oil pump and a screw-cap oil cup) to add lubricating grease, which can squeeze the grease onto the friction surface, preventing it from not reaching the friction surface when applied by hand;

5. Sodium-based lubricating grease is not suitable for use in humid areas due to its strong hydrophilic nature, which makes it prone to degradation;

6. For rotating parts of various mechanisms that do not have oil injection points, a dilute oil can should be used regularly to lubricate the rotating gaps to reduce friction and prevent rusting of the components.
