Robertson Geo designs and builds its own range of winches of varying capacities for deploying subsurface probes on 4-core or co-axial cable.

Each winch is precision engineered for reliable use in the most challenging field applications. The winches are fully compatible with the Micrologger2 surface system (see software) and the full range of Robertson Geo probes, for depths of up to 3,000m.

Mini Winch

The Robertson Geo Mini Winch is portable, compact and robust. Its basic ‘no-frills’ design is aimed at long-term reliability under arduous conditions.

500m Winch

A robust heavy-duty unit, the 500m Winch can be operated from a vehicle battery and is ideal for heavier probes in shallow boreholes.

600m Winch

Of similar basic construction to the 500m Winch, the 600m is mains/generator powered.

1000m/2000m Winch

The standard unit for truck-mounted operations in deep boreholes, the 2000m Winch includes an integral depth wheel and an automatic level wind.

3000m Winch

A heavy-duty electric draw-works designed for deeper hole and oil/gas investigations. Please note the pressure limits of standard Robertson Geo slimhole tools.

2000m Marine Winch

Working experience by Robertson Geo offshore logging crews has led to the modification of the 2000m Winch and the introduction of a Marine variation to resist corrosive, saline conditions.
