This is a vertical drill mounted on a truck chassis—a mobile ground boring installation used in foundation work, pile driving, and deep construction drilling. The drilling head is powered by PTO-driven hydraulics and is capable of delivering significant torque for penetrating soil and rock formations.
The machine comprises two main components. The undercarriage is a MAN ×4 truck with leaf spring suspension, built in 1997 and rated for a gross vehicle weight of 10,500 kg with a payload capacity of 1,500 kg. The drilling superstructure is a Knebel HY79 SBR unit manufactured by Knebel AS in 1995, mounted on the truck bed and driven by power take-off hydraulics.
The drill head features a passage diameter of 168 mm and delivers a maximum torque of 6,000 Nm, with rotational speed adjustable from 0 to 150 rpm. The hoisting system uses a double-chain pull-up mechanism capable of 60 kN pull force and a single-chain pull-down system rated at 30 kN. The bottom clamp provides 600 mm stroke travel. Operation of all systems is controlled via hydraulic cylinders. The installation also includes a turntable with casing clamp, a hydraulic breaker, and a percussion winch system with both pulse and free-fall modes.
A new 12 mm hoisting cable is supplied but requires installation. The machine carries CE marking and complies with Stage I emissions standards. Dutch vehicle registration and operating documentation are available with the sale. The unit was built in 1997 and is in used condition.
