Solutions ready for connection to suspension cranes

DFW end carriages

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 200 ft/min
    • Variable-speed travel motions up to 300 ft./min thanks to inverter-fed drives
