Liebherr Quick Coupling Systems
LIKUFIX
LIKUFIX is the name of the Liebherr fully automatic quick coupling system. The combination
of a hydraulic Liebherr quick coupling system with the LIKUFIX coupling block permits
fast safe changing of mechanical and hydraulic working tools from the operator’s cabin. The
deployment options of a hydraulic excavator and machine productivity can thus be increased
by up to 30%. A worthwhile investment for over 25 years.
Features and customer benefits
• faster and safer changing of mechanical and hydraulic working tools from the operator’s cabin
• machine utilization increased to up to 90% thanks to extended deployment options
• productivity increased by an average of 30% (based on practical customer experience)
• maximum flexibility due to add-on options to all hydraulic excavators with operating
weights of between 8 and 120 tons
• 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
• optimum fluid flow through hydraulic couplings with large cross-sections for fast tool
action and high fuel efficiency
• hydro-mechanical bearing support of the tool coupling block ensuring the long service life
of the hydraulic couplings
• optical and acoustic warning when the quick coupling system is open
• load hook equipped as standard with heavy-duty safety latches for increased safety when
lifting loads
Mounting on tools and hydraulic
excavators of other manufacturers
Practically all hydraulic add-on tools can be fitted with LIKUFIX. Hydraulic excavators from
other manufacturers can be easily fitted with a Liebherr quick coupling system or LIKUFIX.
•
opening and closing of the quick coupling system at the touch of a button
• automatic connecting and disconnecting of the hydraulic lines
during coupling
