Overhead Crane Wheels

Product Overview

Overhead crane wheels play a crucial role in lifting equipment. They support heavy loads during movement and also provide the driving force for the entire system. Moreover, they offer high wear resistance, strong impact resistance, and accurate dimensional control. As a result, these wheels are widely used in gantry cranes, bridge cranes, port machinery, and mining equipment.

Material & Hardness

Manufacturers often choose 60#, 65Mn, or 42CrMo alloy steel to produce overhead crane wheels. In addition, the tread surface requires hardness levels between HRC40–48, while the core must maintain HBS187–229. To balance toughness and wear resistance, the hardened layer depth should remain ≥10mm. For example, container crane wheels made with optimized alloy steel and advanced heat treatment reach HRC55 on the tread, which increases service life by more than 50%.

Structure & Manufacturing Process

The production of overhead crane wheels involves forging, heat treatment, and precision machining. Instead of relying only on traditional forging, modern factories now apply die forging and high-frequency quenching. For instance, YFL-160KW quenching equipment combines CNC rotary heating with water spray cooling. Consequently, the hardening depth becomes more accurate, and wheel quality improves significantly.

Specifications & Applications

Wheel diameters range from Φ100mm to Φ1200mm. In addition, the tapered tread design enhances rail self-alignment during operation. According to the drive type, wheels are divided into driving wheels, which transmit power, and driven wheels, which mainly bear load transfer. Therefore, customers can select the right configuration based on crane type and working conditions.
