Solutions ready for connection to cranes and superstructures

Our DFW end carriages are compact, rail-mounted travel units for direct connection to crane girders and other load-bearing structures. The end carriages consist of a torsionally rigid box section, our DRS wheel blocks and one of our geared motors. They offer excellent travel characteristics – also for high loads. Their strengths in detail:

  • optimum travel characteristics
  • smooth starting thanks to matching drive solutions
  • high operating reliability
  • easy assembly and accessibility
  • for single and double-girder overhead travelling cranes, suspension cranes and travelling structures.

Product information

The benefits at a glance

Safe, reliable and efficient operation
  • Ready for installation for a wide range of operating conditions
  • Torsionally rigid box section with continuous, heavy gauge side plate
  • Reinforced connection with welded diaphragm plates
  • Steel superstructure specified to DIN 15018, lifting class H2, loading group B3
Excellent travel characteristics
  • Smooth running characteristics due to high self-damping effect of the travel wheel material
  • High wheel loads
  • Long service life
  • Anti-friction bearings sealed against dust and lubricated for life
  • Reliable connection between travel wheels and shafts thanks to splined shaft profile
  • Minimum wear on travel wheels and crane runway rails thanks to self-lubricating effect of spheroidal-graphite cast iron
Easy assembly and accessibility
  • Prepared for connection to superstructures such as crane girders and other mobile structures
  • Precise position of the travel wheel axes in relation to the connecting surfaces thanks to machining in a NC machine tool
  • Reliable replacement thanks to reproducible connection geometry
  • Simple adjustment of span dimensions by replacing spacer elements
  • Wear indicator for travel wheels
Tailored drive solutions
  • Various sizes for all output requirements
  • Pole-changing cylindrical-rotor brake motors for travel speeds up to 12.5/50 m/min
  • Variable-speed travel motions up to 63 m/min thanks to inverter-fed drives
