Demag travel wheel blocks are modular industrial components with several key parts. Each part plays a vital role, and its material is carefully chosen to meet the demands of different industrial environments. Below is a detailed introduction to the features, functions, and common materials used in the major components of Demag travel wheel blocks:

Travel wheel

• Function: 

Supports the weight of the entire equipment and ensures smooth operation on the track. Transmits driving forces or movement commands to the rail to guide the equipment along a set path.

• Material: 

Steel (hot-rolled or forged): Suitable for high-load and high-strength environments such as heavy-duty cranes and industrial machinery.

Polyurethane-coated wheel: Ideal for applications requiring noise reduction or track protection, suitable for light to medium loads.

Spheroidal-graphite cast iron (GGG70): Suitable for cost-sensitive environments that do not require frequent high loads.

Bearing

• Function:

Provides low-friction rotational support, ensuring smooth wheel rotation during operation. Handles radial and axial loads to extend the lifespan of the wheel block.

• Material: 

High-strength alloy steel: Surface-hardened for excellent wear resistance and high hardness.

Sealed design: Protects against dust, moisture, and contaminants, suitable for harsh environments.

Housing

• Function: 

Provides overall structural support, integrating the wheel, bearing, and connecting components into one module. Protects internal components from external impacts, dust, and chemical corrosion.

• Material: 

Cast iron: High durability, suitable for heavy-duty and industrial applications.

Aluminum alloy: Lightweight, ideal for mobile or light-duty scenarios.

Steel: High impact resistance, ideal for demanding operating environments.

Mounting plate

• Function:

Serves as the interface for connecting the wheel block to the equipment frame.

Ensures the wheel block can be quickly and securely installed on the equipment.

• Material:

Carbon steel: High strength, suitable for applications requiring strong fixation.

Stainless steel: Ideal for corrosive environments such as chemical or marine engineering.

Seals

• Function:

Prevents lubricant leakage and protects internal components from contamination.

Extends the overall service life of the wheel block, especially during operation in harsh environments.

• Material:

High-temperature rubber: Used in general industrial settings.

Viton (fluorocarbon rubber): Suitable for high-temperature or chemically corrosive environments.

Silicone seal: Performs well in low-temperature applications.

Lubrication system

• Function:

Provides long-term lubrication to reduce friction between bearings and wheels.

Ensures smooth operation under heavy loads or during extended use.

• Material:

Typically uses industrial-grade grease with high-temperature and anti-oxidation properties.

Demag travel wheel blocks integrate high-quality components into a single module, offering efficient, stable, and convenient solutions. Their key features include:

• Modular design: Simplifies installation, maintenance, and replacement. Guide mechanism (optional) buffer (optional) drive shaft (if for driven wheel blocks)

• Versatile material selection: Adapts to various industrial environments, including high-temperature, low-temperature, and corrosive settings. 

• High load capacity: Capable of meeting the demands of heavy loads and continuous operation.

• Flexibility: Options for driven or non-driven wheel blocks, with guide mechanisms and buffers as configurable features.
