Crane systems

Demag Cranes & Components has installed a specialist crane system at Enviropower's energy-from-waste plant in West Sussex. The £12.5m renewable energy facility processes biomass, typically timber and cardboard waste from the construction and demolition industries, for the generation of electricity.

Demag installed a 10t SWL, 13.25m span, double girder grabbing crane.

Mounted on the crane is a wire rope hoist with a 10m3 bucket grab on a 12.4m hook path. The system has cross travel speeds of 3-30m/min, long travel speeds of 4-70m/min and hoisting speeds of 1-16m/min.

The system is fully automated to permit 24h uninterrupted and unmanned operation, with radio remote control also available for manual operation.

Motors are inverter driven for smooth control of movement and accurate positioning, reducing airborne dust. The crane has thermal protection in all motions. Safety features include overload protection, anti derailment and slack rope detection.
