DFW II end carriages

Solutions ready for connection with proven Demag quality for cranes and other load-bearing structures

Demag DFW II end carriages are compact rail-mounted travel units with variable options for connection to crane girders and other load-bearing structures. The end carriages consist of a torsionally rigid box-section profile, Demag DRS wheel blocks, and Demag geared motors. DFW II end carriages can be used for all single-girder and double-girder overhead travelling cranes. To meet your specific needs, our two-wheel and four-wheel end carriages can be combined with Demag drives to offer the performance you need to achieve travel speeds up to 40 m/min (380–400 V) or 48 m/min (480 V). New connection possibilities can increase the wheel base and offer more solutions for your needs.

Our high-quality two-stage pole-changing motors not only deliver enough power, but also provide your crane with outstanding travel characteristics – also with heavy loads. The resulting precision when driving the crane is characterized by powerful starting and perfectly accurate stops. More efficiency for your material handling.

A broad variety of options complement the end carriage: derailment catches, storm protection, rain covers, buffer extensions and rail sweeps all ensure that the crane will continue to work and can also extend its service life. 

Demag DFW II end carriages – helping you maximize your operating safety and reliability.

  • Long service life thanks to the globally recognized quality of our drives
  • Optimum travel characteristics
    • Powerful starting thanks to matching drive solutions
    • Two-stage long travel
  • Larger wheel base for greater flexibility
  • Suitable for special applications
    • Extreme ambient conditions
    • Slow long-travel motion, e.g. 2 m/min
    • Better solution for ambient temperatures higher than +45°C
    • Better solution for hazardous environments, e.g. pickling plants, electroplating, heavy dust production
  • High operating safety and reliability
  • Easy assembly and good accessibility
  • For all Demag single-girder and double-girder overhead travelling cranes, as well as for other load-bearing structures – when two-stage pole-changing travel drives are the best solution
    • For load capacities up to 50 tonnes and spans up to 35 metres
  • Base standard for the steel structure dimensions: EN 13001
