New from Grove is a long-boom version of the GMK4115 (GMK4100 outside the US) that was launched at the Intermat exhibition in France earlier this year.

The four axle 115 ton capacity GMK4115-L has a 197 foot seven section boom (against the 170 feet of the standard GMK4115) that telescopes to its maximum reach in nine minutes. Maximum tip height is 272 feet and the 33 to 56 foot bi-fold hydraulic luffing swing away 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 GMK4115 include a 295 kW (390 hp) Mercedes Benz carrier engine, a 110 kW(147.5 hp) direct fuel injection superstructure engine, and up to 28.8 tons of counterweight.

Gerhard Kaupert, director of engineering for 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. The 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.
