High load capacity combined with wide spans

ZKKE double-girder cranes

A solid investment in handling efficiency and performance

Our double-girder overhead traveling cranes offer exceptional load capacity and minimum deadweight. Their precise and stable geometry provides travel characteristics that minimize wear on the end carriages and runway. In addition, the load hook can be raised between the two crane girders which enables maximum lifting heights.

Product information

The benefits at a glance

High stability and design rigidity

  • Torsionally rigid
  • Connections between the girders and end trucks are manufactured to precise machined tolerances for minimum wear
  • End truck of torsionally rigid, welded box construction
  • Excellent travel characteristics and minimum wear due to low-maintenance drives
  • Travel wheels of highly wear-resistant GGG 70 spheroidal-graphite cast iron with self-lubricating properties

Highly cost-effective

  • Low deadweight reduces cost – crane girders made of computer-optimized box sections
  • Rope hoist helps reduce operating cost due to extended 2m+ service life classification (1,900 hours of service at full load)
  • Reliable monitoring and preventive maintenance due to advanced CAN Bus technology

Efficiency and performance

  • Control pendant suspended for separate travel on the crane girder
  • Power supply to the trolley via high-flexibility flat cable with protective ground conductor
  • Optional radio control with display and proportional pushbuttons
