Tilt damping, function description
Tilt means that the attachment can swing back and forth in the sus-
pension to the boom so that the load hangs straight during the entire
lift movement. Tilt damping means that the tilt movement is coun-
ter-acted.
The attachment's mounting in the boom is hinged and provided with
two hydraulic cylinders that dampen the oscillations. The hydraulic
cylinders are connected crosswise to damping block tilt. Damping
block tilt is supplied with servo pressure from Control valve attach-
ment that is controlled to the tilt cylinders and generates an over-
pressure in the tilt cylinders. Adjustable restrictions between the
connections for piston and rod side in the damping block create re-
sistance that dampens the tilt movement.
