ZKKE double-girder cranes
ZKKE double-girder cranes
A solid investment in handling efficiency and performance
Our double-girder overhead travelling cranes offer exceptional load capacity for a low deadweight. Their outstanding crane geometry also provides for extremely good travel characteristics, which minimises wear on the end carriages and crane runway. The load hook can be raised between the two crane girders, which allows large lifting heights to be achieved. Further strengths?
- High long and cross-travel speeds thanks to high-performance double-girder design
- Low deadweight reduces investment layout
- Crane girders can be adapted to building structure requirements
- Minimum approach dimensions thanks to compact travelling hoist design
- Crane control to meet application requirements: via radio control, control pendant or cab control (optional)
- Maintenance platform and accessible crab facilitate maintenance of building interior fittings (optional)

The benefits at a glance
Highly cost-effective
- Low deadweight reduces investment layout – crane girders made of computer-optimised box sections
- Connections between the main girder and end carriages manufactured to mechanical engineering tolerances for minimum wear
- Increased efficiency thanks to DR rope hoist with extended service life due to Demag 2m+ classification (1,900 hours of service at full load)
- Favourable travel characteristics and minimum wear of the crane runway and travel wheels thanks to low-maintenance drives
- Travel wheels of highly wear-resistant GGG 70 spheroidal-graphite cast iron with self-lubricating properties
- Reduced construction and operating costs thanks to optimised designs
Strong performance
- Particularly high performance thanks to double-girder design for high long and cross-travel speeds
- Optimum utilisation of the available height and space thanks to compact travelling hoist design (minimum approach dimensions and large hook path)
- Particularly high lifting height, as the load hook can be raised between the two crane girders
- End carriages of torsionally rigid, welded box-section design
- Power supply to the crab by means of highly flexible flat cable with protective earth conductor
- 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)
- Control pendant suspended for separate travel on the crane girder with display for installation monitoring
Great versatility
- Optional maintenance platform and accessible crab – for even easier crane maintenance as well as fast and safe access to building interior fittings (lights, radiators, supply lines)
- Optional radio control with proportional pushbuttons
- Optional power and signal transmission via energy chain system
- Large number of fittings can be installed
- Cabin control

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
