4. Device description and
basic mode of operation
4.1 Basic mode of operation
The Pressgun Picco operates electrohydrauli-
cally. The hydraulic pump is driven by means of
an electric motor. The hydraulic fluid pressure
acts on the drive piston at one side, and the
press rolls (5) are attached to the piston rod of
this piston. The press rolls produce the pressing
action as the result of the force being diverted via
the cams of the press jaw (7).
4.2
Electronic monitoring and
LED indicators
The Pressgun Picco is monitored electronically in
order to protect against tampering and in order to
ensure perfect pressing results. The status of any
malfunctions are indicated by light-emitting diodes
(LEDs)(2).
