Do Cranes Need Lubrication?

Do Cranes Need Lubrication?

 

When the 50 ton bridge crane is working, there will be corresponding contact and friction between the parts, so the lubrication of the crane parts is necessary; one of the functions of the crane part lubrication is to improve the smoothness of the crane operation process.

 

1. The lubrication of crane parts can reduce the wear and tear of crane parts during the working process;

 

After the crane parts are lubricated, the flexibility between the parts is higher when the crane is operated, and a layer of oil surface will be formed on the contact surface between the parts, which can relatively reduce the wear of the direct contact between the crane parts.

 

2. The lubrication of crane parts can prevent the corrosion between the parts of the crane;

 

After the crane parts use lubricating oil, the lubricating oil will form a natural protective oil film between the parts, which can avoid the phenomenon of oxidation and rust caused by the direct contact between the crane parts and the air.

 

3. The lubrication of crane parts can be that the contact surface between the crane parts is in a sealed state, which can prevent dust from entering the gaps of crane parts and causing bad operation feeling to a certain extent.

 

4. After the crane parts are lubricated, the mechanical strength of the crane can be reduced accordingly, and the construction work can be better completed.

 

 

Why should crane parts be lubricated

 

1. The crane is a large-scale equipment and machinery that acts on the place. In order to ensure the use effect of the crane, the parts of the crane need to maintain good performance. Therefore, the parts of the crane should be maintained accordingly;

 

2. Each component of the crane has an important influence on its performance, so it is necessary to carry out corresponding maintenance and inspection on these components, which can relatively maintain and prolong the service performance of the crane;

 

3. The main method of maintenance of crane parts is to regularly lubricate the parts for maintenance and inspection. It is necessary to use matching lubricating oil to maintain the rigidity of the machine. Regular inspection can also find out the wear and tear of crane parts in time. for replacement and repair.

 

The use of appropriate lubrication methods and lubricating oils for cranes can improve the quality of the crane, relatively reduce the damage to the crane equipment, and improve the working efficiency and quality of the crane. The lubrication of crane parts has a great maintainability effect on the maintainability of each part of the crane.

 

Lubrication is one of the important measures to ensure the normal operation of the machine, prolong the life of parts, improve efficiency and safe production. Maintenance personnel should fully understand the importance of equipment lubrication, check the lubrication conditions of each movement point frequently, and regularly add lubricating oil (grease) to each lubrication point.

 

 

1. Main lubricating parts

 

① Hoisting of the bridge crane;

 

② Various bearings;

 

③Each gear coupling;

 

④ reducer;

 

⑤ steel wire rope;

 

⑥Hinge point on the brake.

 

2. Precautions for lubrication

 

① Keep the lubricating oil (grease) clean;

 

② Lubricating oils (greases) of different grades cannot be mixed for use;

 

③ Choose suitable lubricating oil (grease) to lubricate according to the specified time;

 

④ Use the pressure grease injection method (use an oil gun or oil pump, screw cap oil cup) to add grease, so that the grease can be squeezed onto the friction surface to prevent it from entering the friction surface when wiping it by hand;

 

⑤ Sodium-based grease should not be used in humid areas, because of its strong hydrophilicity, it is prone to failure;

 

⑥ For the rotating parts of each mechanism without oil filling points, thin oil cans should be regularly used in each rotating gap to reduce friction and prevent corrosion of parts.
