Crane Wheels

Product Description

Flanged crane wheels are mainly used in various types of lifting machines. They are available in multiple configurations, including:

Single rim wheel

Double rim wheel

Non‑rim wheel

Other non‑standard wheels

Applications

Flanged crane wheels are mainly used in various types of lifting machines, including:

Single girder overhead cranes

Double girder overhead cranes

Gantry cranes

Port cranes

And other lifting equipment

Types & Materials

Flanged crane wheels are available in multiple configurations, such as:

Single rim wheel

Double rim wheel

Non‑rim wheel

Other non‑standard wheels

Materials include:

Alloy steels: 42CrMo4, AISI 4140, 41Cr4, A504

Carbon steels: SSW‑Q1R, 65Mn, 1045, 1055, 1060, 1070

Ductile iron: Grade 400, 500, 600, 700, etc.

Manufacturing Process

Shandong Xingyuan Machinery applies different manufacturing processes based on the material, with precise control over quenching and tempering temperatures. This ensures the wheel achieves the required metallographic structure and mechanical properties.

Heat Treatment Methods

Three heat treatment methods are available according to different requirements:

1. Through Hardening & Tempering

Wheel surface hardness: HB 300–380

Mainly used for standard crane products

2. Surface Medium Frequency Quenching & Tempering

Wheel surface hardness: HB 300–380 or HRC 50–56

Mainly used for products requiring low wheel center hardness but high wheel surface hardness, where whole heat treatment is unsuitable

3. Through Hardening & Tempering (High Hardness)

Wheel surface hardness: Up to HRC 50–56

Hardness decreases with depth due to material differences

Forged alloy steel wheels have a hardened layer depth up to 15 mm with low hardness attenuation

Mainly used for port cranes, bucket‑wheel excavators, bucket‑wheel stacker reclaimers, and other heavy‑load products

Failure Modes & Selection Considerations

Flanged crane wheels are replaced due to:

Flange wear

Flange breakage

Mechanical overloads characterized by pitting and spalling

Each of these in‑service factors must be carefully considered before selecting the combination of wheel design, material, hardness pattern, and heat‑treating technology.
