ZKKE Double-Girder Overhead Travelling Cranes

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 cabcontrol (optional)
• Maintenance platform and accessible crab facilitate maintenance of building interiorfittings (optional)

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 DMR or DBR rope hoists
• 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 modern 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 display and proportional pushbuttons
• Optional radio control with power and signal transmission via energy chain system
• Large number of fittings can be installed
• Cabin control
