ZPKE double-girder overhead travelling cranes

Efficient, high-performance indoor cranes

Large lifting heights for small spans

ZPKE double-girder overhead travelling cranes are the cost-effective entry-level models for Demag indoor cranes. ZPKE profile-section girders impress by virtue of their high degree of efficiency and offer an alternative to box-section girders – especially for small spans. The lifting height is high however – because the load hook can be raised between the two crane girders. The use of rolled steel sections as crane girders and specially developed rope hoist trolleys create an economically attractive overall package for double-girder overhead travelling cranes.

Further strengths of ZPKE

  • High long and cross-travel speeds thanks to high-performance double-girder design
  • End carriages of optimised design to suit the structure
  • Minimum approach dimensions thanks to compact trolley design
  • Crane control to meet application requirements: by radio control, pendant controller
  • Low-sway travel motions for smooth handling and exact positioning of loads thanks to optional frequency-inverter control
  • Crane components offering high operating safety and reliability

Product information

The advantages at a glance

Highly cost-effective

  • Connections between the main girder and end carriages manufactured to mechanical engineering tolerances for minimum wear
  • Increased efficiency thanks to extended service life of the rope hoist due to Demag 4m classification (6,300 hours of service at full load)
  • Favourable travel characteristics and minimum wear of the crane runway and travel wheels thanks to low-maintenance drives
  • Travel wheels made of highly wear-resistant GGG 70 spheroidal-graphite cast-iron with self-lubricating properties

Strong performance

  • Particularly high performance as a result of double-girder design for high long and cross-travel speeds
  • Optimum utilisation of the available height and space thanks to compact trolley design (minimum approach dimensions and large hook path)
  • Particularly high lifting height, as the load hook can be raised between the two crane girders
  • Power supply to the trolley by means of highly flexible flat cable with protective earth conductor

Extremely safe and powerful load handling

The smart Demag SafeControl system affords increased safety during crane operation

  • Reliable monitoring and preventive maintenance thanks to CAN bus technology
  • High transmission reliability (category 3 to DIN/EN 954)
  • Pendant controller suspended for separate travel on the crane girder with display for installation monitoring
  • Crane travel speeds up to 60 m/min

Great versatility

  • Optional radio control with display and proportional pushbuttons
  • Radio control with power and signal transmission via energy chain system
  • Large number of fittings can be installed
