A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the quarry face in order to place the drill hole in the required position. This system used small diameter holes and was not only terribly inefficient, but very dangerous due to flying rock as a result of the inaccuracy of the drilled borehole. With a maximum drilling depth of 100 meters and the ability to drill diameters from 50 to 200 mm, this rig meets many construction needs efficiently. Max. Drilling Depth Easy to operate for single-person use. Customizable equipment to suit specific needs. High mobility with a crawler-type design.
