The new model will mount an all terrain upper on a trailer body. The 55t GSK55 will be a cheaper option than regular all terrains, and can be used with the end user’s choice of tractors.

Manitowoc says the GSK55 ‘combines the lift ability of Grove all-terrain cranes with the “flexibility and mobility of a standard on-road truck”.

The GSK 55 has its own power source, a 93kW Iveco engine mounted on the trailer. The standard design of the trailer means it is not tied to one brand of tractor, Manitowoc says, and can be steered from the left- or right-hand side.

The three-axle trailer can be pulled by a two-axle tractor, and will put down only 9t per axle with its full counterweight of 11.6t.

The crane’s lifting specifications match the GMK3055, the all terrain that provided the upper structure: it can lift 55t, and has a 43m main boom. An optional 8.7m/15m swingaway jib is available, for a maximum tip height of 60m.
