Quick change systems
Mechanical and hydraulic quick change system
What is a quick change system?
The quick change system is a tough, low-wear arrangement for rapid and safe changeo-
ver of mechanical and hydraulic add-on tools.
The technical advantage:
• The right tool can be put to use, every time and in every situation
• No need to undo nuts, bolts, or pins
• Modular add-on system (quick and easy retrofitting of hydraulic quick change systems
to LIKUFIX)
• Positive-fit system: That means long service life and no stress on the mechanical lock-
ing elements during work.
• Hydraulic coupling system with spring bearing arrangement
• Designed for the toughest operational situations
• Added safety when locking in place thanks to position monitoring instead of pressure
monitoring
• Backhoe bucket can also be used as high bucket
• Can also be fitted to excavators from other manufacturers
The convenience advantage:
• No problem at all in retrofitting existing hydraulic excavators
• Low operating and maintenance costs
• Add-on tools can be changed from the driver’s cab
The financial advantage:
• Short-term, uncomplicated load increase thanks to two load lift hooks fitted as standard
• Add-on tools can be changed in only a matter of seconds – and that means increasing
the rate of utilisation thanks to the same machine taking on entirely different tasks
• Excavator as multifunctional tool carrier
• Tools can be used by several carrier devices
