For pulling the sounding tubes out of the ground after testing, Gouda-Geo supplies wedge clamps with hardened jaws in various sizes in combination with a pulling bowl. These wedge clamps can both be placed on top of the hydraulic and manual pulling devices.
The largest advantage of wedge clamps is the fact that they do not really damage the tubes. They are safe and reliable devices and come at really affordable prices. Because of the large clamping range the pulling of worn sounding tubes will not cause any problems.
The wedge clamps are robust, deliver high clamping forces and are capable of managing high pulling forces. Easy handling and positioning because of the handles.
By having the pulling bowl separate from the jaw sets, it is possible to apply different jaw sets (for different tube diameters) with the same pulling bowl.
