Pressing
Description and equipment technology
The pressing process works with single sheet piles. The
sheet piles are friction-locked to the pressing cylinders
by clamps. Initially the sheet piles are pressed into the
soil via the rope crowd system, which already makes a
penetration of several metres possible. Thereafter, sheet
piles are pressed alternately by the pressing cylinders.
Moreover, the weight of the basic machine as well as the
skin friction of the idle sheet piles are used as resisting
force for the pressing process.
With the help of process data recording (PDE) all work-
related process data can be displayed and recorded in
the cabin.
The pressing process is controlled either manually or
automatically.
