Optimum performance and cost-effectiveness

Our EKKE single-girder overhead travelling cranes feature maximum rigidity for a minimum deadweight. This keeps the load on the crane runway to a minimum – and a cost-effective design can be selected for the building. This approach provides you with a cost-effective solution. They also include a hoist unit with high handling speeds and the benefits of outstanding crane geometry, resulting in exceptional travel characteristics. For greater overall efficiency. What other benefits do EKKE units offer?

Crane girders made of computer-optimised box sections

End carriages of torsionally rigid, welded box-section design
Improved cost-effectiveness offered by the hoist thanks to extended service life as part of the Demag standard design (1,900 hours of service at full load)
Improved load handling thanks to increased lifting and cross-travel speeds
Low-sway load motions thanks to infinitely variable cross-travel speeds

Benefits at a glance

High stability and design rigidity
  • Torsionally rigid, enclosed box-section profile with reinforced connection (welded diaphragm plates)
  • Engineering tolerances in the crane girder connection area
  • End carriages of torsionally rigid, welded box-section design
  • Favourable travel characteristics and minimum wear thanks to low-maintenance drives
  • Travel wheels of highly wear-resistant GGG 70 spheroidal-graphite cast iron with self-lubricating properties
  • Optomum travel characteristics with minimum wear of crane runway and travel wheels
Highly cost-effective
  • Low deadweight reduces investment layout – crane girders made of computer-optimised box sections
  • Increased efficiency thanks to rope hoist with extended service life due to Demag 2m+ classification (1,900 hours of service at full load)
  • Reliable monitoring and preventive maintenance thanks to CAN Bus technology to meet tomorrow’s demands for high data transmission reliability (category 3 to DIN/EN 954)
  • Optimum utilisation of the available height and space thanks to compact travelling hoist design and large hook path
  • Reduced construction and operating costs thanks to optimised designs
Efficiency and performance
  • Minimum wear of crane runway and travel wheels thanks to low-maintenance drives
  • Control pendant suspended for separate travel on the crane girder with display for installation monitoring
  • Power supply to the crab by means of highly flexible flat cable with protective earth conductor
  • Optional radio control with power and signal transmission via energy chain system
  • Optional radio control with display and proportional pushbuttons

Equipment options

With our wide range of equipment options, we match our universal 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.
