Demag wheel block meets the demanding needs of high-temperature and heavy-duty applications. These wheel blocks are integral components in various types of cranes, conveyors, and automated guided vehicles (agvs) that operate in harsh conditions. This article delves into the key parts of the Demag wheel block that are optimized for high temperatures and heavy loads, and the principles behind their design.

Key parts of the Demag wheel block for high-temperature and heavy-duty applications

• Wheel material and design

The wheel is one of the most critical components in a Demag travel wheel block, especially for heavy-duty and high-temperature operations. Demag uses high-strength alloy steel for the wheels in such environments. This material offers superior tensile strength, enabling the wheel to withstand heavy loads without deformation. Additionally, the alloy steel can endure higher operating temperatures, maintaining its strength and durability even under extreme conditions.

For high-temperature environments, heat-treated steel or forged steel is often used. These materials undergo specific heat treatments, such as quenching and tempering, to enhance their hardness and resistance to wear. The high-temperature resistance ensures that the wheels perform efficiently even when exposed to direct heat, such as in foundries, steel mills, or furnaces.

• Bearings

The bearings in Demag wheel blocks are designed to minimize friction and provide smooth rotation, even under heavy loads and high temperatures. High-performance bearings made from high-carbon steel or ceramic composites are typically employed in these applications. These materials are chosen for their ability to resist thermal expansion and retain their operational characteristics at elevated temperatures.

Furthermore, these bearings are often equipped with advanced seals that protect against contaminants, such as dust or molten metals, which can cause premature failure in extreme environments. The seals also help to retain lubrication, ensuring smooth operation and reducing maintenance needs.

• Housing and structural components

The wheel block housing, which supports the entire assembly, is made from cast iron or high-strength steel alloys. Cast iron provides excellent durability and resistance to heat, while high-strength steel alloys offer greater flexibility and tensile strength under heavy loads. These materials are also treated for corrosion resistance to prevent deterioration when exposed to high temperatures or aggressive chemicals.

• Lubrication system

The lubrication system plays a crucial role in maintaining the efficiency and longevity of wheel blocks in high-temperature and heavy-duty applications. Heat-resistant lubricants are used to ensure that the bearings and other moving parts remain well-lubricated, even when operating at temperatures exceeding 200°c (392°f). These lubricants are formulated to withstand high temperatures without breaking down, ensuring that friction is minimized and the wheel block operates smoothly under load.

Demag also incorporates sealed lubrication systems to prevent contaminants from entering the system, thus extending the life of the components.

Demag's wheels for high temperature and heavy-duty applications are carefully designed to provide excellent performance, durability and reliability. By using advanced materials, precision engineering design and innovative lubrication systems, demag ensures that its wheels can cope with extreme conditions.
