Low profile boring machine

The Robbins 53RH is a low profile raise drill for holes ranging from 1.2 to 2.4 m (4-8 ft.) in diameter. This unique multipurpose raise drill is able to perform upwards boxhole boring as well as conventional raiseboring with no need to modify the drive assembly. The main gearbox features two float boxes to easily switch from raise to boxhole mode. Two double-acting telescopic cylinders can exert equal thrust in both directions. The 53RH is cleverly compact yet powerful, granting it greater flexibility to tackle a variety of tough applications where workspace is restricted.
