JCB will launch 427 and 437 wheeled loaders at Bauma, powered by Stage IIIB/Tier 4 Interim Cummins engines. First seen in prototype form at last year’s Intermat show, the two loaders are powered by the Cummins QSB6.7 engine, which offers a 9.4% increase in torque over the previous model. This drives through a lock-up converter and customers can choose a standard four-speed or optional five-speed transmission, which delivers a 16% drop in fuel consumption. In-cab noise levels have been reduced to just 68dB(A

Element Six, the synthetic diamond division of DeBeers, has developed a revised design for its D Power road picks, claiming greatly extended working life. The D Power road pick will use a polycrystalline diamond (PCD) tip with an improved head design that incorporates tungsten carbide to provide greater protection to the steel pick mount. The company claims that the D Power road pick can deliver up to 40 times the life of a standard carbide pick, providing reduced downtime, increased efficiency and a better
