Strand Lifting Technology - PAUL Maschinenfabrik GmbH & Co. KG

CONTROL SYSTEM
Operation of the strand jacks takes place centrally with the
aid of a user-friendly control system. It visualizes up to 16
strand jacks on a display, so guaranteeing full control of the
hydraulic pressure, piston stroke and anchor assembly status
(open/closed). If required, the display can be supplemented
by additional strand jacks. The central control system is connected
by means of a bus cable to the individual hydraulic
pump units and processes signals in real time.

The following operating modes are supported by the control
system:
• Set-up mode and pre-load stroke
• Automatic lifting and lowering mode
• Manual mode for corrections
8
The control system monitors the lifting or lowering mode. It
is possible to select between pressure and path monitoring.
If the prescribed limiting values are exceeded, the operator
is warned and, if necessary, the current process is stopped
in order to carry out the necessary corrections. In the automatic
mode, the control system regulates the stroke
and pressure automatically.
