Crane Wheels featuring tapered roller bearings and overall quenching and tempering heat treatment for superior strength and durability

The active wheel assembly includes components such as the drive shaft, bearing housing, bearings, wheel, shaft sleeve, key, and other fittings. This assembly connects with the reducer, motor, and brake to drive the passive wheel assembly for travel. The traveling mechanism on trolleys typically employs single-flange wheels.

Wheels are cast from 55# steel, undergo rough and finish turning on lathes, followed by medium-frequency hardening of the tread surface, and are precision assembled with pressed-in bearings. Available specifications include: Φ100, Φ200, Φ250, Φ300, Φ350, Φ400, Φ500, Φ600, Φ700, Φ800, Φ900, Φ1000, Φ1200, and other sizes.

• Double-flange wheel assemblies are primarily used for bridge traveling mechanisms of cranes with capacity below 50T
• After surface hardening, tread hardness reaches HB330-380
• Overall quenching and tempering heat treatment further enhances performance
• ZG50SiMn material increases wheel load capacity by 20% with a 15% price increase
• All bearings in double-flange wheel assemblies are tapered roller bearings
• Single-flange wheels are commonly used for trolleys of overhead and gantry cranes with flange height of 20mm to 25mm
• Standard material for single-flange wheels is cast ZG340-640 unless otherwise specified

The horizontal skew value of crane traveling mechanism wheels is a critical technical parameter. Excessive skew can cause rail gnawing, increase running resistance, generate vibration and noise, accelerate wear on rails and wheels, and significantly reduce crane service life. Various crane manufacturing specifications stipulate permissible limits for wheel horizontal skew values.
