Modular DRS Wheel Blocks for Cranes & Transfer Vehicles

The DRS wheel block system represents a high-performance modular solution designed for demanding material handling equipment, including stacker cranes, overhead cranes, and automated transfer vehicles. Available in multiple models such as DRS112, DRS116, DRS200, DRS250, DRS315, DRS400, and DRS500, each unit is engineered to deliver exceptional load capacity—ranging from 2.75 to 40 tons per wheel—while supporting smooth and reliable travel across steel or aluminum tracks.

Robust Material Selection for Diverse Operating Conditions
DRS wheels are manufactured using high-grade materials, including:

• Ductile Iron (GGG 70): Delivering high tensile strength and impact resistance, ideal for heavy-load and high-cycle applications.

• Polyurethane & Polyamide: Providing excellent wear resistance, vibration damping, and noise reduction, with minimal damage to running surfaces.

Modular Design with Multiple Connection Options
The system supports flexible integration with almost any structural setup. Four standardized mounting configurations are available:

• K-Type: Top connection

• B-Type: Pin connection

• S-Type: End connection

• W-Type: Side connection

These preset interfaces allow for direct bolting or welding, simplifying installation and alignment in both new and retrofit applications.

Integrated Drive Units with Optimized Performance
When paired with a matched reducer and motor, the DRS system forms a complete and compact traveling drive unit. Key features include:

• High ground clearance for obstacle clearance and debris resistance.

• Custom reducer design tailored to specific wheel loading and travel speed requirements.

• Optional horizontal steering wheel sets and buffers for enhanced guidance and impact protection.

Easy Installation & Alignment
Designed with usability in mind, the DRS system enables quick assembly and precise positioning:

• The housing can be directly mounted to the upper steel structure.

• Tight manufacturing tolerances and machined reference planes ensure accurate fit-up.

• Laser calibration support allows for fast and repeatable alignment.

• Asymmetric housing design enables wheel replacement without recalibrating top-mounted connections.

• Lateral adjustment capability after mounting ensures perfect alignment on hollow sections or beams.

Low Maintenance & Enhanced Service Life
Built to operate reliably under high loads and in harsh environments, the DRS system incorporates several maintenance-reducing features:

• Five-chamber sealed cast-iron housing protects bearings and wheels from mechanical damage and contaminants.

• Large grooved ball bearings or tapered roller bearings come with lifelong lubrication.

• Self-lubricating GGG-70 wheels reduce friction and resist wear.

• Integrated rim wear indicator enables remote and visual inspection, supporting predictive maintenance.
