Steel gets a smooth move

As part of the development of a new 75,000ft2 warehouse facility, Demag Cranes & Components has installed two crane systems at Rainham Steel's Scunthorpe distribution centre.

Rated at 7 tonnes + 7 tonnes SWL, the double girder travelling cranes have spans of 30.8 and 31.5m. Both cranes are equipped with two Demag DR-PRO wire rope hoists, upon which magnets are mounted. The use of magnets for the lifting process eliminates time consuming 'slinging' of loads and improves safety by excluding operators from the lifting area.

The cranes have long travel speeds of 8-80m/min, cross travel speeds of 5-25m/min and hoisting speeds of 1-16 m/min. Drive motors feature AC frequency inverters for variable speed, providing smooth movement and precise positioning accuracy in all motions. Operation of the cranes, hoists and magnets is via a user friendly HBC radio control.
