Sandvik DE740 heavy duty core drill

T e c h n i c a l s p e c i f i c at i o n

The powerful and versatile DE740 is a mid size coring drill rig cable of pulling and running rods and casings in 9 m (30 ft) lengths. The 11 m (36 ft) long drill mast features excellent mast handling and assembly characteristics and has the possibility to lowers to near horizontal position. It also has a possibility to telescope mast making it 1,8 m (6 ft) shorter and a pull back of 133,5 kN (30 000 lbf) and a pull down of 67 kN (15 000 lbf). The DE740 is a truly space efficient deep hole core drilling rig that has proven to be advantageous on sites where a smaller foot print is required.
