A wheel block system is a rail-mounted crane component consisting of a set of wheels and a supporting frame to carry loads during movement. Capable of handling loads up to 40 tons, the wheels can have diameters of up to 500 mm. In addition to being used as crane accessories, these wheels are also suitable for moving heavy loads in various industrial applications.

The Demag DRS 400 wheel block system provides significant advantages from project planning through to installation commissioning. These wheel blocks offer versatile solutions for a broad range of applications, delivering exceptional performance with maximum load capacity relative to their travel wheel diameter.

PROTECTED TRAVEL WHEELS

• The housing, enclosed on five sides, shields the travel wheels from external mechanical influences.

• Constructed from high-quality, corrosion-resistant die-cast aluminum, the housing features a powder coating up to 90 µm thick for DRS sizes 112 to 200.

• For DRS size 250, 315, 400 and 500, the housing is made of high-strength spheroidal graphite cast iron with a RAL 7001 finishing coat.

• Any unnecessary housing openings can be sealed with plugs included in the delivery.

PRECISE ALIGNMENT

• Laser system for easy and accurate alignment of DRS 400 wheel blocks.  

• Pre-installed brackets on the housing of all sizes, from DRS 112 to DRS 500, allow for quick and precise alignment of wheel blocks across multiple trolleys.

EASY TO INSTALL AND RIGID DESIGN  

DRS 400 wheel blocks are engineered for easy connection to superstructures, ensuring smooth starting and braking, which minimizes wear on the runway.  

• Compact housing design with precise position tolerances.  

• Accurate dimensions across all axes for seamless integration.

• Special stiffeners incorporated for enhanced rigidity and stability.
