Double girder gantry cranes

  • Low dead weight
  • Low contact surface for wind
  • Spans of up to 50 meters possible
  • Higher stability than conventional box girder constructions
  • Less abrasion by weather conditions
  • Suitable best for outdoor operations
  • Also available as semi-gantry crane

Our innovative double girder gantry cranes use the stable OVAL profile not only for the crane girders, but also for the pillars. Round shapes and durable constructions are characteristic for our gantry cranes in patented design. In addition to weight savings and the high stability the OVAL profile also provides good aerodynamic characteristics and prevents the girders from corrosion by water or dirt sedimentation. These properties make our double girder gantry cranes best suitable for outdoor operations.
The double girder gantry cranes feature the familiar benefits of the single girder gantry cranes and allow also heavy-duty applications by the use of a parallel arrangement of two OVAL profile girders. Consequently, capacities of up to 350 tons and spans of up to 50 meters are possible. Due to the modular system our double girder gantry cranes are specially designed according to your needs.
