The KLEMM KD3428 hydraulic drifter has three motors. This makes it suitable for particularly heavy overlay drilling. With its heavy impact piston, the hydraulic hammer achieves the highest single impact energy.
As an alternative to the conventional hydraulic damping unit, a version with mechanical, rotating damping unit is also available.
