Key Features
- Hydraulic pull-back and hold-down replace manual winching: steadier feed on casing and auger strings, less crew fatigue.
- Three power options on one frame — 6 hp diesel, 7.2 / 8.2 kW petrol, or 4.0 / 5.5 kW electric.
- 180 kg bare, 220 kg with winch and hydraulic module; every module lifts by two men.
- 180 N·m low gear on 42 / 30 mm rods, 50 m at 46 mm.
- Rated for auger work as well as coring: hydraulic hold-down keeps the flight steady in clay.
- Module frames bolt together on site, so a crew of two can rig up without a crane.
