WISON-APB for water depths up to 550 m

The WISON-APB-Classic is capable of performing CPTs and taking soil samples at depths up to 550 m (water depth + drilling depth). It requires a drill string with an inner diameter of at least 4” (101,6 mm) and a drill tower clearance of 11 m. Its pushing tool is available in three versions: each with its own pushing capacity, length and stroke. The WISON-APB-Classic comes with an electric winch that is self-tensioning for heave compensation. The winch allows the tool to travel at a maximum speed of 2 m per sec inside the drill string.
