How to prolong the life of overhead and gantry cranes?

Overhead and gantry cranes are generally best placed in a flat and wide warehouse with no obstacles so that they can be maintained and managed better. When the overhead and gantry crane is not in use, management is also very important, rather than just leaving it somewhere and not caring about it. This is not conducive to the maintenance of the crane’s performance and the flexibility of the next operation. Therefore, how to prolong their life is a very necessary thing.

How to manage the overhead and gantry crane during storage?

Based on our experience, we focus on the following points:

• It is necessary to use a thicker plastic bag to package the whole overhead and gantry crane. In other words, it is best not to leave it there at any time, leaving it exposed to the outside naturally. This is not good. We need to manage it like a car, which is to use thick plastic bags to package everything except the tires, which can protect it from some damage and interference from the outside world.
• Carry out special personnel management, and assign special personnel to check and find problems on the crane from time to time, so that we can know in time whether there will be any problems during the placement period. Therefore, it is a very important management measure. It is best to implement a duty system and a technical management system for personnel management, which includes both normal management and technical guidance management.
• Early warning and monitoring should be established. This is for the safety of the crane to prevent other people with bad intentions from taking some illegal actions. The storage situation inside can also be understood through the monitor, so that the information can be used to improve its monitoring. These 3 points should be the basic management measures for the placement of cranes, except for different management for different cranes.

What are the maintenance items of overhead and gantry cranes?

• Lubrication

The performance and life of each mechanism of the crane depend to a large extent on lubrication. Lubrication is one of the essential contents of the maintenance of the crane equipment. The quality of lubrication directly affects the operation of each crane mechanism and the life of the crane parts, and also affects safe production and production efficiency. Therefore, operators and maintenance personnel must frequently check the lubrication of the lubrication points of this equipment and replenish and replace lubricants on time.

The principles to be followed in lubrication maintenance: All places where the shaft and hole are in motion, as well as mechanical parts with friction surfaces, must be lubricated regularly. Due to the different conditions of use of the crane (utilization rate and use environment, etc.), the lubrication of different parts should be properly controlled according to the specific situation.

• Wire rope

Pay attention to the broken wire of the wire rope. If there is broken wire, broken strand or the wear reaches the scrap standard, the new rope should be replaced in time. The wire ropes that can be selected include pphosphatic coated wire rope, galvanized wire rope and smooth wire rope.

• Hoisting equipment

The hoisting equipment must be checked regularly.

• Pulley block

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

• Wheel

Regularly check the wheel rim and tread. When the wear or crack of the wheel rim reaches 10% thickness, replace the new wheel.

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

• Brake

Should be checked once every shift.

The brake should operate accurately, and the pin shaft 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.
