Hydraulic System VOLTO TIC
5-12 10/04
Function
Transport position (DW1) The following graphics shows the VOLTO 1050T in its complete transport
position.
• Actuate the double-acting additional control unit (DW1) of the tractor
so that the volume flow flows via port (14).
• The outer arms are retracted by means of hydraulic cylinders (1).
When the end position has been reached, the stroke limiting valve (5)
opens.
• Volume flow flows into the hydraulic cylinders (2) via the open stroke
limiting valve (5) and the flow divider (11).
• While the hydraulic cylinders (2) are extended, the block-type ball
valve (7) is closed.
• After the end of the stroke of hydraulic cylinders (2), followed by a
pressure rise to 130 bar, the hydraulic cylinders (3) are retracted via
the pressure sequence valve.
• When retracting of the hydraulic cylinders (3) has been started, the
stroke limiting valve is closed.
• At the end of the raise process of the hydraulic cylinders (3), the side
arms come to rest on the supports on the longitudinal beam.
• In this transport position, the side arms are safeguarded by the lock-
up valve units (13).
