High torsional rigidity

EKDE suspension cranes with box-section girders

Overhead handling – for loads weighing up to 16 tonnes

Our EKDE suspension cranes are mainly characterised by high torsional rigidity thanks to their welded box-section design. The cranes run on tracks that are simply attached to the existing roof structure – columns to support the crane runway are not needed. This design saves time and money. And it saves space, leaving your entire workshop area available for production. Further benefits?

  • Computer-optimised box-section profile used for the crane girder for optimum load distribution
  • Specific sections of the workshop can be served
  • Lateral overhangs to extend the cross-travel path beyond the runway span
  • Loads can be handled immediately adjacent to the building wall by means of girder ends tailored to your application requirements
  • Engineering tolerances for minimum wear

Product information

The benefits at a glance

High stability and design rigidity

  • Crane girder made of torsionally rigid, enclosed box-section profile with reinforced connection (welded diaphragm plates)
  • Engineering tolerances in the crane girder connection area
  • Optomum travel characteristics with minimum wear of crane runway and travel wheels
  • Travel wheels of highly wear-resistant GGG 70 spheroidal-graphite cast iron with self-lubricating properties
  • Optimum anti-corrosion protection of all parts thanks to pre-treatment of steel components to industry standard

Efficient handling

  • Crab of low-headroom design with DR rope hoist offering particularly favourable hook approach dimensions to serve the largest possible area
  • Power supply to the crab by means of highly flexible flat cable with protective earth conductor
  • Control pendant suspended for separate travel on the crane girder with display for installation monitoring

Individual configuration

  • Optimum adaptation of the crane girder to the building design thanks to computer-optimised box-section profile
  • Latching devices available for transfer of trolleys from the crane girder to a monorail track
  • Optional radio control with display and proportional pushbuttons

Equipment options

With our wide range of equipment options, we match our standard cranes to the individual requirements of your application:

  • automatic height adjustment of the control pendant to facilitate load attachment
  • control by pendant switch
  • control via bi-directional radio control with proportional pushbuttons
  • smooth starting helps to avoid load sway
  • end carriages with horizontal guide rollers eliminate skewing and thus the lateral forces which otherwise act on the crane runway
  • limit switches or slack rope relays protect the hoist and load from damage
  • bypass control system prevents collisions with obstacles along the crab travel path
  • anti-collision protection and crane distance controls ensure the safe operation of several cranes on one runway
  • cranes fitted with two crabs make it easy to handle long and awkward loads
  • comprehensive range of load handling attachments satisfies the most varied requirements.
