Long boom GMK4100

New from Grove is a long-boom version of the GMK4100 (GMK4115 in the US) all terrain that was launched at the Intermat show earlier this year in Paris.

The four axle 100 tonne capacity GMK4100-L has a 196 foot seven section boom (against the 170 feet of the standard GMK4100) that telescopes to its maximum reach in nine minutes. Maximum tip height is 272 feet and the 32 to 55 foot bi-fold hydraulic luffing swingaway jib has a 16 foot insert. The company said that the extra reach makes the crane particularly suitable for the assembly of top slewing tower cranes.

Features shared with the standard GMK4100 include a 295 kW (390 hp) Mercedes Benz carrier engine, a 110 kW (147.5 hp) direct fuel injection superstructure engine, and up to 26 tonnes of counterweight.

Gerhard Kaupert, director of engineering on Grove's all terrain cranes, said, “The customer voice remains the driving force behind product design. That is why we created a four-axle model with extra reach, as our customers look for increasingly quicker ways to erect Potain tower cranes. Investments made in research and development for the GMK4100-L have been significant, and we anticipate that the GMK4100-L will generate the same strong levels of interest as the standard model.
