Grove GSK 55: Trailer mounted mobile crane

Manitowoc again introduces a new innovative mobile crane concept named GSK 55. The upperstructure already is known from its AT-version, the GMK 3055, fitted with 43 meters of telescopic boom and a double folding jib with 8,7 and 15 meters of lenght as option. The special idea about the GSK 55 is its carrier, as it is a specially designed 3-axle trailer-chassis. For moving the crane this chassis can be combined with a common prime mover that usually is available in every truckfleet.

The GSK 55 offers the same load capacities and working radius like the GMK 3055, though it has not its mobility offside the road. But the great benefit of this concept is the road mobility between different job sites. Combined with a 2-axle truck and full ballast of 11,6 tonnes, the GSK 55 has a maximum load per axle of 9 tonnes. The trailer chassis is fitted with 93kW-motor from Iveco. With this motor all crane functions are driven, including the outrigger system. At coming Intermat in Paris Grove will show the GSK 55 in iron for the first time.
