Demag Cranes & Components has
installed two double girder travelling
cranes, with spans of 30.8 and 31.5m
at Rainham Steel’s Scunthorpe
distribution centre.

The cranes, both rated at 7t + 7t
SWL, have two Demag DR-PRO wire
rope hoists, upon which magnets are
mounted. 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 – 16m/min. Drive motors
feature AC frequency inverters for
variable speed, providing smooth
movement and precise positioning
accuracy in all motions.
