The solution for harsh applications

RS wheel block system

Performance and versatility – also under extreme conditions

Our RS wheel block system is engineered for high-temperature applications, up to 250 °C, or wherever stainless steel housing is needed. Many travel wheel designs and possible connections to superstructures make the system suitable for universal applications.

Further strengths include:

  • Five sizes with load capacities ranging from 7,700 lbs to 39,600 lbs (3,500 kg to 18,000 kg)
  • Housing made of steel or stainless steel
  • Many travel wheel contours as standard
  • Four variants for connection to the customer's superstructure
  • Driven by Demag offset gear motors
  • Integrated connections, e.g. for torque brackets, guide roller arrangements and buffers.

Product information

The benefits at a glance

High performance for extreme applications

  • Long service life of the steel and mechanical elements
  • Innovative design for high-temperature applications up to 150 °C
  • Optional furnace carriage bearings up to 250 °C
  • Stainless design for applications in the chemical industry, foods sector and in aggressive environments (size RS 125)


  • Wide variety of standard travel wheel designs
  • Housing made of steel or stainless steel
  • Five sizes with load capacities from 7,700 to 39,600 lbs (3,500 to 18,000 kg)  (RS 125 to RS 400)

Simple assembly

  • Load-bearing block enclosed on 5 sides with connecting surfaces featuring multiple bore holes
  • Rapid installation and removal for all connection variants
  • Reamed lateral bore holes for the pin connection
  • Integrated connections for torque brackets, guide roller arrangements and buffers

Optimum drive

  • Positive connection to the gearbox hollow shaft (involute splined profile) guarantees reliable torque transmission
  • Particularly suited for reversing operation typically found in travel applications
  • The Demag modular system includes the D1 torque bracket (fitted direct to the wheel block) or D2 torque bracket (fitted to the customer's superstructure) to accommodate the torque transmitted by the drive
