Lifting product introduction: wheel set2021.08.16
Wheel set, a supporting device that supports the crane's load and makes the crane reciprocate.
Structural composition: wheels, axles, brackets, bearings, bearing boxes.
Processing technology: Casting wheels generally use ZG340-640 cast steel (65Mn, 42CrMo forgings can also be used when there are special requirements), with pure materials and sufficient materials. In order to reduce wheel wear, spot damage, and increase service life, especially after surface heat treatment, the depth of the hardened layer is not less than 15-20mm, and the product hardness is as high as HB300-380. Standardized production technology, accurate numerical values, fine products, avoiding rail gnawing, vibration, noise and other problems caused by excessive deviation of the deflection value.
1. Super load: fine workmanship, strong structure;
2. Support customization: high production accuracy, solving customer demand problems;
3. Superior performance: low noise, stable driving and long life.
Product model: complete models, non-standard products, can be customized according to drawings.
1. The position of the wheel should be such that the width center plane is consistent with the symmetric center of the two bearing boxes;
2. The bearing box support plane should be parallel to the center surface of the wheel width, and the deviation should not exceed 0.2mm;
3. The inclination of the wheels in the vertical direction should not be greater than 1mm;
4. If the wheel rolling surface has uneven wear or unevenness, stop using it and replace it as soon as possible;
5. When replacing wheels, install and replace in strict accordance with the operating requirements.
