6 Liebherr Quick Coupling Systems
Hydraulic quick
coupling system
Mechanical working tools can be changed effortlessly from the operator’s cabin at the
touch of a button with the Liebherr hydraulic quick coupling system. During tool change
two-handed operation, the electronic position sensors and visual control by the operator
from the driver’s cabin of the left locking pin guarantees maximum safety - ensuring that
quick coupling system and working tool remain reliably connected.
Improved safety thanks to the sturdy heavy-duty safety latches on the load hook: they bear
100 % of the maximum permissible hook load (basic safety) - and thus considerably more
than the 10% required by EN 474.
Features and customer benefits
• faster safer changing of mechanical working tools from the operator’s cabin
• optimum transmission of digging forces like those of directly attached tools
• unique level of safety when changing tools afforded by position monitoring of the locking
pin by electronic position sensor instead of pressure monitoring of the locking cylinder
• straightforward reliable visual locking control from the operator’s cabin with a clear view of
the left locking pin
• optical and acoustic warning when the quick coupling system is open
• load hook equipped with heavy-duty safety latches as standard for increased safety when
lifting loads
Areas of application
• for frequent tool changes (of predominantly mechanical working tools)
• opening and closing of the quick coupling system at the touch of a button
• manual connecting and disconnecting of hydraulic lines
