Wheel Block System
The crane wheel block has solid structure and strong load-bearing capacity. It is used in bridge, gantry and various types of lifting equipment and can be customized according to working conditions.
Product Description
The wheel block assembly is a critical operating component for bridge cranes, gantry cranes, and large mobile equipment. It consists of the wheel, axle, bearing, hub, wheel housing flange connector, and necessary sealing and lubrication systems. It directly bears the entire crane's travel load and torque, and plays a crucial role in the crane's operating smoothness, positioning accuracy, and safety.

Wheel Block Assembly Components and Materials
● Wheel: Made of high-strength alloy steel or case-hardened steel, surface-turned or heat-treated, and dynamically balanced. Options include inlaid steel, solid steel, or polyurethane coated, depending on the rail material.
● Hub: Integrated or fitted with the wheel, constructed of high-strength alloy or ductile iron, machined to ensure proper alignment.
● Axle & Coupling: The axle is typically made of structural alloy steel, heat-treated, and precision-turned. The coupling transmits driving force and compensates for minor misalignment.
● Bearing: Select spherical roller bearings, cylindrical roller bearings, or spherical bearings to ensure load capacity and life.
● Seals & Lubrication: High-performance dust-proof seals and oil-fillable lubrication are used to adapt to the working environment.
● Mounting Assembly: Precision-machined mating surfaces ensure reliable connection and positioning between the wheel assembly and the bridge/end beam.
Features and Advantages of Crane Wheel Blocks
● Strong Load Capacity: Materials and heat treatment processes ensure excellent fatigue life of the wheel and bearings even under heavy loads.
● Smooth Operation and Low Noise: Precision machining and dynamic balancing reduce vibration and noise, protecting the track and bridge structure.
● Easy Maintenance: Modular assembly design, standardized interfaces, and lubrication points facilitate on-site inspection and quick replacement.
● High-Standard Bearings: Selected heavy-duty bearings from well-known brands offer strong load capacity and high rotational accuracy, ensuring smooth wheel assembly operation.
● High Adaptability: Supports a variety of wheel and track combinations, allowing customization based on working conditions.
