ZKKE double-girder overhead travelling crane

DEMAG ZKKE double-girder overhead travelling cranes offer exceptionally high capacity with low dead weight. The excellent crane geometry ensures optimum travelling characteristics and thus minimises wear of the travelling gear and the crane runway. A great lifting height is an additional advantage.

Connection between the crane girder and the travelling gear with machine tolerances for minimal wear

Increased economy thanks to the extended service life of the DR wire rope hoist through DEMAG 2m+ (1,900 hours of service life at full load)

Optimal travelling characteristics and minimal wear of the crane runway and wheels thanks to maintenance-free drives

Optimal use of room height and floor area thanks to compact design (short approach dimensions and great lifting height)

Safe monitoring and preventive maintenance thanks to advanced CAN bus technology for high transmission reliability (category 3 according to DIN/EN 954)

Maintenance platform and walkways for easier maintenance and quick, safe access to hall equipment (lighting, heating units, power supply lines)

Parameters and design

ADVANTAGES OF THE SOLUTION
High cost-efficiency
Low dead weight saves investment costs – the girder is a computer-designed welded structure
Travel wheels made of GGG70 ductile cast iron with self-lubricating properties
Reduced construction and operating costs thanks to the optimised design
Performance-oriented
Exceptional performance thanks to the double-girder design for high crane and trolley travel speeds
Extremely large lifting height, because the hook can be drawn up between the two crane girders
Crane travel units in a welded box-section design with increased torsional rigidity
Power supply to the trolley via a highly flexible flat cable with a protective conductor
Separate travelling control unit with a display on the crane girder for equipment monitoring
Wide range of applications
Optional remote control with a display and proportional buttons
Remote control with energy and signal transmission via an energy chain
Various expansion options
Can also be equipped with a crane cab
