Warning!
From a safety point of view,
the quick coupler with its locking function
is a particularly important part of Rototilt®.
A system function defect can cause costly
downtime, and in the worst case, serious
personal injury. Follow the instructions
carefully and note the warnings given in
this document. If there is a problem or
you discover a fault with the Quick coupler’s
locking function, contact your dealer.
The QC quick coupler is fitted with QuickChange
automatic hydraulic connections which enable
hydraulically-operated tools to be changed from the
driver’s cab. Note that tools must also be equipped
with QuickChange hydraulic connections.
Function
The quick coupler consists of a quick coupler body
(pos. 1) and an H cylinder unit (pos. 2) with two
integral hydraulic cylinders, linked by two locking
pistons (pos. 3). The center section of the cylinder
unit has space for hydraulic quick connect fittings.
When the unit’s cylinders move, the quick coupler
locks and the hydraulics are connected simultaneously.
Connection and disconnection of tools and
hydraulics is done with the same cylinder movement.
The coupler is also fitted with a mechanical dirt
protector (pos. 4) which stops dirt getting into
the quick connect fittings when using tools without
QuickChange quick hose connections.
When the quick coupler locking function is in the
locked position without the QuickChange tool, the
cover that stops dirt getting into the quick connect
fittings will be closed. This closed position should
always be used if the machine has no tool attached.
Cylinder unit movement acts on the cover, which is
opened by a rod (pos. 5) fixed to the quick coupler
frame.
Optional extras
The quick coupler can be fitted with an optional
sensor (pos 6 and 7) to monitor the locking unit and/
or or an electrical plug (pos 8) to the tool connected.
Also refer to the Control system section.
