11 Liebherr Quick Coupling Systems
The use of the right tool and optimum utilization of construction machinery contribute to the economical
and prompt execution of building projects. Fast and easy tool changing is essential for high machine
utilization and productivity, while also achieving a high standard of safety. This is only possible if the oper-
ator can see whether the quick change system and working tool are correctly connected following tool
change. The Liebherr hydraulic quick coupling system offers this option, and thus guarantees maximum
productivity and occupational safety.
• visual control: straightforward reliable visual locking control from the operator’s cabin with a clear
view of the left locking pin
• position monitoring: unique level of safety when changing tools afforded by position monitoring
of the locking pin and the quick coupling system by electronic position sensors instead of pressure
monitoring of the locking cylinder
• alarm signalling: optical and acoustic warning when the quick coupling system is open or not locked
correctly
• safety in the event of pressure loss: reliable connection even in the event of pressure loss in the
locking cylinder hydraulic line thanks to form-fit coupling
• safety during load lifting: sturdy heavy-duty safety latches on the load hooks bear 100 % of the maxi-
mum permissible hook load (basic safety) for a high standard of safety when transporting heavy loads
• safety against damage: hydraulic couplings are recessed or integrated into solid metal plates
• safety against incorrect operation: perfected design to reduce
danger of damage caused by incorrect operation
