Crane Wheel Blocks

In crushing workshops, grinding-flotation workshops, and large machinery repair workshops of mineral processing plants, critical equipment such as heavy-duty bridge cranes and gantry transfer cars undertake heavy lifting and material handling tasks over the long term.

1. High-frequency heavy loads and strong impacts: Equipment frequently undergoes heavy-load starting, braking, and running operations, enduring high-intensity impact and alternating shear loads, with a working class typically reaching ISO 8.

2. Complex workshop operating environments: Processing areas are often accompanied by mineral dust, moisture, or humidity, while machine repair workshops face rigorous tests of high-intensity, continuous operation.

3. Operational stress concentration: During the frequent lifting of heavy components (such as ball mill liners, large motors, and reducers), the frame and track system endure complex alternating stresses.

4. Limitations of traditional materials: Traditional gray cast iron or light ductile iron housings are extremely prone to cracking or deformation under strong vibrations and alternating stresses caused by heavy loads.

Core Features of DRS Wheel Blocks

To address the above challenges, we proposes a solution utilizing Demag DRS 112-250mm wheel blocks to replace the original wheel assemblies. The DRS wheel block is designed for heavy-duty environments and features the following key technical characteristics:

Five-Sided Enclosed High-Strength Housing: The fully enclosed cast housing effectively blocks dust and moisture while significantly reducing maintenance frequency.

High-Quality Ductile Iron Material: Manufactured from casting steel, the wheels provide exceptional wear resistance and a load capacity of up to 40 tons.

Fixed Alignment and Quick Replacement Design: The split housing structure allows for fast wheel replacement without realigning, minimizing equipment downtime.

Core Application Benefits 

Significantly extended overhaul intervals: The overhaul interval of the travel mechanism achieves a substantial increase of over 3 times.

Elimination of unplanned downtime: Completely prevents equipment failures caused by housing cracks and early bearing wear, ensuring the continuity of mineral processing production and the efficient safety of workshop maintenance operations.
