Wheel Block System

Port gantry cranes are core equipment in modern terminals, handling the efficient transfer of containers and bulk cargo between ships and the shore. These cranes operate on coastal rails for extended periods, requiring them to withstand salt spray corrosion, high humidity, and dust ingress, while also ensuring precise positioning and reliable operation under heavy-load conditions. The Demag DRS rail travel system, with its integrated design and high-performance components, provides port cranes with stable, durable, and easy-to-maintain travel support.

Structural Features and Core Functions of the DRS Travel Wheel Block

The Demag DRS travel wheel block utilizes a factory-pre-assembled, integrated design that combines the wheel, housing, bearing, and sealing system into a single unit. It offers the following core functions:

1. High Load Transfer Capacity: Evenly distributes the crane's self-weight and the total hoisted load, ensuring balanced force on the rails.

2. Smooth and Quiet Operation: An optimized tread and rail contact design reduces vibration and operating noise, enhancing positioning accuracy.

3. Anti-Derailment & Wind Resistance: Works in conjunction with double flanges or guide rollers to enhance travel stability under conditions such as high winds and curves.

4. Energy Saving & Reduced Consumption: A low rolling resistance structure decreases drive power requirements, improving the overall energy efficiency of the machine.

5. Anti-Slip & Derailment Prevention: Special tread textures and flange designs effectively cope with wet rail surfaces, ensuring operational safety.

Material and Protection Configurations for Marine Environments

To adapt to the specific corrosive, humid, and high-impact environment of seaports, the DRS system offers various material and surface treatment options:

Conclusion

With its professional design for harsh port conditions, diverse material options, and convenient maintenance features, the Demag DRS rail travel system is a key component ensuring the long-term stable operation of port gantry cranes. It provides a highly adaptable and reliable travel solution for both new projects and existing equipment upgrades.
