with built-in block cylinder.
An unlockable check valve is integrated into the block cylinder.
The block cylinder reduces sealing points in the hydraulic system of the
quick coupler to an absolute minimum.
When the excavator is in operation, there is a standby pressure of 30 to 40 bar on the "closed" side.
The "open" side is connected to the tank without pressure. Operating pressure: 40 to 200 bar
The quick coupler can be opened and closed with pilot pressure
(at least 30 bar)
or with a quick coupler valve.
For more information, see the relevant
hydraulic diagram!

and structure.
** A measuring connection
** is screwed into the block cylinder for pressure control.
** This makes it easy to connect a pressure
** pressure gauge under pressure up to 400 bar.
