The HD202 E is a self-contained, fully hydraulic crawler drill rig, CE conforming and especially
designed for difficult drilling conditions which require particularly compact and mobile
equipment. It features a compact and robust design, simple and safe controls and excellent
gradeability as well as high efficiency. In addition, the rig has a modern and operator friendly
hydraulic system and all movements of the drilling unit are easily controllable which ensures
optimum operation even under severe conditions.
The step-less adjustable tracking control system ensures that the machine can be safely moved
even in tight working conditions.
