company news about How to maintain the crane trolley?

Today, cranes are important material handling equipment and are often used in many industries such as manufacturing, logistics, construction, steel, and energy. As an important part of the operation of the crane, the trolley undertakes the key tasks of the lifting mechanism and lateral movement. Its operating status directly affects the safety and efficiency of the entire crane. So how to extend the service life of the trolley? Maintenance is essential. Next, we will explain in detail how to maintain the trolley and extend its service life.

1.Importance of car maintenance

Crane trolleys work under high intensity, frequent starting and braking, and complex environments all year round. They carry the weight of electric hoists or main hooks during operation. Once a failure occurs, it will not only cause equipment downtime, but may also cause serious safety accidents. Regular maintenance can not only extend the service life of the equipment, but also improve operational safety and reduce maintenance costs.

2. Daily maintenance points of crane trolley

• Track inspection and cleaning

The operation of the trolley depends on the stability and cleanliness of the track. You need to regularly clean the dust, oil and debris on the track, and check whether there are welds, breaks, deviations or wear to avoid track abnormalities that cause the trolley to deviate or get stuck.

• Wheel and bearing maintenance

Check the degree of wear of the wheels and whether there are cracks or deformations. At the same time, add grease to the bearings to prevent excessive running resistance or bearing burning.

• Transmission system inspection

For trolleys driven by gears, chains, or couplings, the transmission system should be regularly checked for looseness, wear, or breakage, and tightened or replaced as needed.

• Motor and brake system

The trolley is usually equipped with an independent drive motor. Check whether the motor is running normally and whether the cable is aging or damaged. The brake should be kept clean, sensitive and reliable, and the braking torque should be adjusted if necessary.

• Limit device and safety switch

The limit switch is an important safety device to prevent the trolley from over-running. Its sensitivity and response speed should be checked regularly to prevent misoperation or failure.

• Bolt tightening and structural inspection

Carry out a comprehensive inspection of the fasteners of the trolley body, especially the load-bearing parts such as the operating mechanism and hanging points, to ensure that there is no looseness, cracks or structural deformation.

Although the maintenance of crane trolleys may seem trivial, it is the basis for ensuring the safe and stable operation of the entire equipment. CATET recommends that users establish a scientific maintenance system, arrange regular inspections by professionals, and reasonably adjust the maintenance frequency based on on-site working conditions. By "maintenance is more important than repair", the cost reduction and efficiency improvement of equipment can be truly achieved.
