Grove announced its new four-axle AT, the GMK4100 (GMK4115 in the US) at Intermat 2008 in April. It is a new design, Grove says, and has a 52 m six-section Megaform boom with Twin-Lock pinning. A 10 to 17 m bi-fold swingaway jib is available, and two additional 5 m inserts further increase jib length. Maximum tip height is 82 m.

The GMK4100 can travel below 12 tonnes per axle with 6.3 tonnes of counterweight, together with the bi-fold swingaway jib, a 16 tonne hook block, and riding on 16.00 R25 tyres. Maximum counterweight is 26.1 tonnes.

Competing with the GMK4100 is the new 100 tonne capacity Terex-Demag AC 100/4. The four axle AT will be seen in iron for the first time at the Bauma 2009 exhibition in Germany next year. It will have a five section 50 m pinned boom for a strong lifting chart. At a 10 m radius with the boom fully extended, the preliminary chart shows it will lift 12 tonnes. Maximum boom and jib combination will be 69 m.
