Demag, one of the largest suppliers of cranes in South Africa, recently supplied a 10-t V-Girder crane to a local copper coil factory. The crane was a new production crane which was installed into an existing production bay.
“Prior to recommending the V-Girder product, Demag conducted wheel loading comparisons for the company. The results showed that the lower wheel loadings of the V-Girder crane meant that no changes were required to the existing supporting gantry structure, thereby offering a substantial cost saving. Additionally, the V-Girder crane is 17% lighter than conventional box girder cranes,” says Richard Roughley, manager for Industrial Equipment Sales at Demag.
“The V-Girder crane offers benefits such as greater efficiency – as the oscillation of the crane girder dampens 30% faster than a conventional crane – resulting in an increased load handling rate. The 10-t crane has a 17,5 m span with a lifting height of 6 m. The unique design of the V-Girder will also allow more light into the factory, creating a safer and better lit environment for technicians to operate in. The V-Girder has double the structural design life compared to a conventional crane performing similar functions,” adds Roughley.
While Demag is renowned for its competitiveness combined with high level of technical expertise, critical factors for this client in selecting the V-Girder also included the guarantee of delivery. Initial discussions enabled Demag to correctly assess the required technical specifications and manage the critical six-week delivery timeframe.
“We believe the technical advantages of the V-Girder crane coupled with availability of crane sets, enabled us to me meet the fast turnaround time from order to delivery that the client required. The importance of availability is often overlooked, but it does play a major role when production outputs are dependent of new equipment being installed within the required production window,” says Roughley.
