Major upgrade for ROC L7 range

2007 Jan 03

Two of Atlas Copco?s most successful crawler rigs, the ROC L740 and the ROC L740CR have undergone major upgrades, resulting an even better package for drillers. Both drill rigs benefit from a unique cylinder-feed system which incorporates an aluminium feed beam that delivers precise and consistent feed force. Increased rigidity, strength and lower weight are also advantages of the aluminium construction.

The power pack on the ROC L7 has been given a major boost with the inclusion of a bigger engine which delivers 328 kw enabling it to offer up to 40 kw for drilling compared to 30 kw available on previous models. This results in a potential 33 per cent increase in the rate of bit penetration. The engine also meets the latest  environmental standards and limits for exhaust emissions.

In the new cabin, the operator benefits from improved space, visibility and comfort and reduced noise levels. Enhanced air conditioning and heating capabilities provide a comfortable cabin environment in any climate, while a rear facing camera allows the operator to see behind the drill rig.

A larger compressor (254 l/s vs 228 l/s) and the ability to drill larger holes (180 mm vs 165 mm) round up the upgraded package.
