Overhead Crane Wheels Block Assembly
Overhead crane wheels are critical components in the crane’s traveling mechanism, bearing heavy loads and ensuring the safe guidance of the crane along a predetermined track. In overhead cranes, the main wheel sets used include LD gear crane wheel sets, hoist trolley wheel sets, round bearing housing wheel sets, round bearing box crane wheel assembly, and 45°split bearing box crane wheel assembly.
These are suitable for various types of overhead crane traveling mechanisms, such as electric single-girder cranes, electric single-girder suspension cranes, double-girder overhead cranes, and foundry overhead cranes.
LD Gear Crane Wheel Assembly
The LD gear crane wheel assembly is a device used to support the crane and its load, enabling the crane to move back and forth along the track. It is an important component of the crane’s traveling mechanism.
Components:
The LD gear crane wheel assembly consists of four parts: wheel shaft, wheel rim, bearing, and gear ring. The primary material for the LD gear crane wheel is 45# steel, which is surface-hardened to provide good quality at a low cost.
Materials:
- The wheel shaft is made of 45# steel, with tempering treatment, achieving a hardness of HB217-HB255. It features grease holes for lubrication.
- The wheel rim is cast from 45# steel, then finely machined and surface-hardened. The tread surface has a hardness of HB300-HB380, with a hardened layer thickness of 8mm-12mm and a hardness of no less than HB260 at a depth of 10mm.
- The outer surface of the wheel is coated with black anti-rust paint to prevent corrosion.
- The bearings are deep groove ball bearings, with main models including 314, 412, 318, and 414. Each set of LD wheels includes two driving wheels, two driven wheels, and the corresponding LD shaft.
Parameters:
The specifications for LD gear crane wheel assembly mainly include two sizes: Φ300 and Φ400, with groove widths of 70mm and 90mm. Other diameters can also be custom-made to non-standard specifications.

| LD300 | ø270 | ø300 | ø70 | ø150 | ø75 | 70 | 38 | 270 |
| LD400 | ø370 | ø400 | ø90 | ø190 | ø100 | 90 | 40 | 280 |
Features:
- The LD gear crane wheel assembly does not have a bearing box; the bearing is directly installed inside the wheel, resulting in a simple structure, high cost-effectiveness, strong part interchangeability, and easy procurement.
- Adjusting the crane wheel when it bites the rail or derails is not convenient.
- Replacing and disassembling the hoist wheel can be quite troublesome.

Features:
- The bearing housing is designed with a 45-degree split, effectively reducing the contact stress between the wheel and the rail, thereby extending the wheel’s service life.
- The 45-degree split design ensures a more even stress distribution across the wheel, reducing local stress concentrations and enhancing the wheel’s durability and stability.
- This design allows stable operation in various complex conditions, including high temperatures, high humidity, and dusty environments.
- The 45-degree split design also makes the wheel easier to disassemble and replace, reducing maintenance time and costs.
