When performing CPT tests over water or in very soft soils, the use of a catching clamp is very much recommended. It holds the CPT sounding tubes or casing tubes when they are not gripped by a clamp or pulling piece.
Practically all penetrometer rigs supplied by Gouda-Geo can be equipped with an integrated hydraulic catching clamp. Since it is practically impossible to equip existing rigs with a hydraulic catching clamp later on, Gouda-geo has developed this retro-fittable mechanical catching clamp.
Easy to fit and easy to use.
