Technical Data
Hydraulic tilting of the grab
X, Y and rotation ± 100°
The hydraulic tilting with inclination measuring and monitoring of the operator's cabin guarantees a verticality of the diaphragm wall of 1:800. To certify the verticality of the trench the measured data can be stored and printed out. (Patents in many countries).

Hydraulic
Diaphragm Wall Grab
HSWG
General Remarks
The hydraulic diaphragm wall grab HSWG is equipped with a permanent measuring and control system which makes it possible primarily to recognize any deviation of the vertical excavating direction immediately, and to indicate it to the control panel of the operator and secondarily to correct any deviation of the vertical position by means of a modification of the direction of the grab. Thus, high accuracy is obtained also at deeper depths (more than 50 m) and the construction of diaphragm walls by means of grab excavation is thus perfected. The hydraulic diaphragm wall grab operates free of noise and vibration.
Operation is easy compared to the mechanical diaphragm wall grab. By means of the special suspension via two ropes, each of which is deflected once, the hydraulic diaphragm wall grab can be operated by means of a smaller carrier unit whereby a more economical application with improved mobility is achieved.
The HSWG XY 200° is equipped with a deviation control system for the x-axis and the y-axis, as well as with a rotation control including data read-out and monitoring system.
