emag Service will modernise four crane installations operated by IMPERIAL Logistics
International with a comprehensive package of measures. The specialist for transport and supply chain solutions has awarded a contract for the refurbishment of four pro- cess cranes, which have served a steel coil store at its location in Bochum, Germany, for 16 years. Besides the replacement of the crane bridges and the installation
of a new crane control system, the forthcoming modernisation project will also include imple- mentation of synchronised control for the long-travel motion. In addition, IMPERIAL Logistics International has placed an order for the refurbishment of the entire crane runway.
Store served by four cranes The four identical process cranes entered service at the location in Bochum in 1999. Besides storing
steel coils that are delivered to them by a shuttle, the cranes, which operate on two parallel runways, ensure that coils are staged in time for further transport by truck or rail. The double-girder overhead travelling cranes, which are manually controlled from a cab, have a load capacity of 36 tonnes. The four cranes handle some 2.7 million tonnes of steel every year. Following a detailed review by the Demag modernisation experts, a package of measures was
defined for the crane installations: • Replacement of the 35 m-long crane bridges, which are rated for a higher loading group classification (H3 B5)
• Replacement of the end carriages with corner-bearing end carriages and frequency inverter-fed drives • Installation of complete new crane electric equipment including the control system, which now meets the requirements of Performance Level d and Safety Category 3 to DIN 13849-1.
