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
