Maintenance Skills of Crane Wheels

 

Wheels are important traveling parts of cranes. They bear weight, guide movement, buffer shock, and maintain balance. They rub against the rails for a long time and need to have good wear resistance.

 

The main forms of damage to crane wheels are wear, crushing of the hardened layer and pitting. The material of crane wheels is generally ZG430-640 cast steel. In order to improve the wear resistance and life of the crane wheel surface, the tread should be subjected to surface heat treatment, requiring the surface hardness to be HB300-350 and the quenching depth to be no less than 20mm.

 

Wheel advantages

1. Strong load-bearing capacity, able to bear the huge weight of the crane and the heavy objects it transports, ensuring safe and stable operation.

2. Good wear resistance, can maintain good shape and performance during long-term use, reduce replacement frequency and reduce costs.

3. Smooth operation, making the crane smooth and smooth during movement, helping to ensure the accuracy and safety of lifting operations.

4. Adapt to a variety of working conditions, with a solid and reliable structure, safe and durable.

 

The horizontal deflection value of the crane wheel is an important technical parameter of the crane. Excessive deflection value will cause rail gnawing, increase running resistance, generate vibration and noise, aggravate rail and wheel wear, and greatly reduce the service life of the crane wheel. Therefore, the manufacturing technical conditions of various types of cranes must specify the allowable value for the horizontal deflection of the wheel.

 

In the application, the horizontal deflection value of the crane wheel of the operating mechanism is controlled mainly by taking corresponding technical measures according to different product structures. The more common design structure with relatively simple process measures is: assemble the crane wheel to the bracket to form a wheel group, install and adjust the horizontal deflection of the crane wheel on the main structure of the crane, and then fix it.

 

Focusing on rail systems for more than 20 years, Glory Rail has very rich experience in wheel maintenance and replacement. Depending on the location where the wheel is used and the on-site working conditions, the wheel is provided with double rims, single rim or no rim. We have high-quality wheel producers. Can produce forged wheels, cast wheels as well as machined wheels. The material is made of high-quality special steel to ensure longer service life and better stability.
