Ball clamps

Ball clamps are available for several applications. The pulling ball clamp is installed in the upper beam for easy retrieval of the Cone Penetration Testing rods during pulling and the catching ball clamp is installed in the underbeam, preventing that CPT rods fall back into frictionless holes while pulling. The clamps are availabable for Cone Penetration Testing rods and casing pipes with Ø25, Ø36, Ø45, Ø56 en Ø85 mm diameters. They are suitable for installation in CPT unit types HYSON LW and HYSON 200 kN.

Combined push/pull clamp

Most types of Cone Penetration Testing units can be provided with a combined push/pull clamp. In case of the HYSON 100 kN-LW it enables the use of CPT rods with 1000 mm length instead of 500 mm, resulting in less screw thread connections and easier and quicker operations. The clamp is available for Cone Penetration Testing rods Ø25 en Ø36 mm.

Mechanical push/pull clamp

In the HYSON 200 kN the mechanical push/pull clamp can be installed. For this clamp several clamping inserts are available for handling more types of rods and pipes, like for instance Ø25, Ø36, Ø45 and Ø56 mm diameter.

Hydraulic push/pull clamp

The hydraulic push/pull clamp is suitable for pushing and pulling rods in the diameter range of Ø36-60 mm. Any diameter within this range can be handled. Switching between rods with a diameter of 36 and 56 mm is done by simply turning a tap at the frontside of the clamp. The clamp is fully automatic. The control system in the automatic Cone Penetration Testing cycle makes sure that the clamp opens and closes at exactly the right moments. The heavy-duty clamp is suitable for handling rods up to a pushing force of 300 kN.
