4 Liebherr Quick Coupling Systems
Mechanical quick
coupling system
• manual opening and closing of the quick coupling system
• manual connecting and disconnecting of hydraulic lines
Liebherr’s mechanic quick coupling system is the perfect solution when aiming to increase
the flexibility and productivity of machinery while keeping investment costs to a minimum.
The sturdy construction, proven over many years, impresses with its straightforward, safe
and reliable mechanical design. After releasing the screw fastening pin, the two locking pins
with internal double threading are manually retracted from one side and then inserted follow-
ing tool attachment.
A safety latch on the load hook of the quick coupling system affords additional safety as
it prevents unintentional unhooking of the load. The safety latches on the load hook of the
Liebherr quick coupling system offer additional safety. They can bear 100 % of the maximum
permissible hook load (basic safety) - and thus considerably more than the 10% required
by EN 474.
