For wheel loads up to 88,000 lbs (40,000 kg)

DRS wheel block system

Modular system for tailor-made solutions

Our DRS wheel block system is a versatile travel wheel system that's perfectly integrated into our modular drive system. Eight finely graded sizes with load capacities of up to 88,000 lbs (40,000 kg) per wheel provide the right wheel block for every application. Our large selection of travel wheels and innovative wheel designs ensure a solution to nearly any travel rail and operating condition.

high performance range and maximum load capacity
many travel wheel shapes as standard as well as customer-specific designs
4 variants for connection to the customer's superstructure
high-quality housing with optimum protection of the travel wheels and bearings
high rigidity
direct connection of optional accessories
laser alignment system for wheel blocks on multiple travel units.

Product information

The benefits at a glance

Exact configuration

8 sizes with load capacities ranging from 6,000 lbs to 88,000 lbs (2,750 kg to 40,000 kg) per wheel
Wheels of various shapes and designs – made of spheroidal-graphite cast iron (GGG 70), polyamide or featuring Hydropur tyres

A: Guided on both sides by flanges for rail systems
B: Wheels without any flanges, optionally fitted with lateral guide rollers, also with concave shape or contour to customer specifications
D: Wheels guided by a flange on one side for units running at floor level
E: Larger diameter wheels without a flange for increased ground clearance
S: Wheels of prismatic, trapezoidal or concave shape for guided applications
F: Flangeless wheels with a Hydropur tyre for high acceleration & quiet running characteristics
C: Flangeless, concave polyamide wheels for quiet operation

Many connection variants

Prepared mounting surfaces for virtually any connection: from top and end connection arrangements with bolted and welded connection elements, to side and pin connection arrangements

K: Top connection
B: Pin connection
S: End connection
W: Side connection

Tailored solutions

Complete travel units with precisely matching geared motors from the Demag modular drive system
High rigidity thanks to special stiffeners
High ground clearance for wheel blocks due to compact system design. Complete drive units with gearbox engineered to match the wheel load
Horizontal guide roller arrangements and buffers in various sizes and designs (optional)

Simple assembly

Housings ready for direct connection to superstructures
Simple connection to superstructures thanks to tight design, effective housing position tolerances and precise geometry in all planes
Laser alignment system for simple and precise wheel block alignment
Simple wheel replacement without the need for re-alignment of top connection thanks to patented asymmetrical housing
Wheel blocks can also be moved and aligned laterally after they have been installed in hollow sections and beams (for top, end and pin connection arrangements)

Minimal maintenance

Cast housing enclosed on five sides reliably protect the travel wheels against mechanical influence
Generously dimensioned grooved ball bearings which are lubricated for life, tapered roller bearings from size DRS 250
Travel wheels made of self-lubricating spheroidal-graphite cast iron (GGG 70) for low friction and high resistance to wear
Integrated wear indicator on wheels with flanges for remote visual diagnosis
