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.
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
