The MAN Knebel HY79 is a directional drill mounted on a truck chassis, designed for foundation and borehole work in construction. This machine combines the mobility of a truck-mounted platform with specialised drilling and casing installation capability, making it suited for site preparation and subsurface investigation in building and civil engineering projects.
The drilling installation is mounted on a MAN 10.163 truck chassis configured as 4×4 with leaf spring suspension, manufactured in 1997. The Knebel HY79 SBR drilling body was built in 1995 by Knebel AS. The machine is driven by Power Take-Off (PTO) hydraulics, enabling independent operation of the drilling head and auxiliary systems without requiring a separate engine.
The pull-up system is rated to 60 kN using a double-chain configuration, while the pull-down system develops 30 kN and operates via a single chain. Both systems are controlled through hydraulic cylinders. The bottom clamp has a maximum opening of 600 mm. The drill head features a ø168 mm passage, develops a torque of 6000 Nm, and operates across a speed range of 0–150 rpm. The machine includes a turntable with casing clamp, a hydraulic breaker, and a percussion winch system offering both pulse and free-fall modes. A new 12 mm cable is included but requires installation.
The machine carries CE marking and meets Stage I emissions classification. Dutch vehicle registration is available. Original service books are present with the equipment. Total payload capacity is 1.5 tonnes. Engine hours recorded at 12,849. The machine is located in the Netherlands.
