Double-Girder Overhead Crane Information

The benefits at a glance

High stability and design rigidity

  • Torsionally rigid
  • Connections between the double-girder cranes 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 double-girder crane
  • Power supply to the trolley via high-flexibility flat cable with protective ground conductor
