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

The 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 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.
