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