The solution for harsh applications

RS wheel block system

Performance and versatility – also under extreme conditions

Our RS wheel block system is suitable for applications in which a housing made of sheet steel is required, such as for impact loads. The RS system is also employed in high-temperature applications up to 250 °C or wherever stainless steel housing is needed. Various travel wheel designs and possible connections to superstructures make the system suitable for universal applications.

Further strengths include:

  • 5 sizes with load capacities from 3.5 tonnes to 18 tonnes
  • Housing made of steel or stainless steel
  • Many travel wheel contours as standard
  • 4 variants for connection to the customer's superstructure
  • Driven by Demag offset geared motors
  • Integrated connections, e.g. for torque brackets, guide roller arrangements and buffers.

  • Special design for high-temperature applications up to 150 °C
  • Or with furnace carriage bearings up to 250 °C
  • Stainless design for applications in the chemical industry, the foodstuffs sector and in aggressive environments (size RS 125)


  • Wide variety of standard travel wheel designs
  • Housing made of steel or stainless steel
  • 5 sizes with load capacities from 3.5 tonnes to 18 tonnes (RS 125 to RS 400)

Very easy 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
Torque brackets
Torque brackets: D1 (fitted direct to the wheel block), D2 (fitted to the customer's superstructure)

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
