Abstract (en)
The device has a load holding device, which is divided into load holding fork-lift sealed locking section (12) in the pressure balance and into a magnetic switching valve. The valve is switched between a flow switching position, which is open to a pre-control circuit (7) and a non-flow switching position, which releases the control side for return motion. The valve is integrated in the circuit for control side of the pressure scale.
