Grove launches four-axle AT

25 April 2008

This month sees Grove launch a new 80 tonne all-terrain, the GMK4080-1 (GMK4100 in the US). It replaces Grove's existing four axle model, the GMK4075-1, while retaining some of its design features. Philippe Cohet, MCG executive vice president, EMEA region, cited versatility, compact dimensions, a strong lifting chart and impressive reach as primary features of the new model.

The GMK4080-1 will pick 6.6 tonnes with its six section Twin- Lock Megaform boom fully extended to 51 m and set at a at a radius of 20 m. With a hydraulic luffing jib and 6 m extension, the maximum tip height is 75 m.

The GMK4080-1 can be configured in 'Taxi' or 'Maxi' modes. In Taxi mode, the crane is within 12 tonnes per axle with 9.3 tonnes of counterweight, 15 m hydraulic swingaway, 16 tonne hook block and 16.00 R25 tyres. In Maxi configuration, capability is increased by an extra 6 m hydraulic swingaway insert and counterweight to a maximum of 19.3 tonnes. Eight counterweight configurations are possible, from 1.8 tonnes up to the maximum.

Features carried over from the GMK4075-1 include the ZF AS-Tronic transmission and 290 kW Mercedes- Benz OM 501 LA engine. A two-stage transfer case has been added to increase agility at lower speeds. Front overhang on the new model, at 1,800 m, is 263 mm less than its predecessor and total length is 12.5 m, which is 265 mm shorter than the outgoing model.

First customer for the GMK4080-1 is German haulage firm Grohmann.
