Quick Coupling
Systems
Areas of application
No matter whether in road construction, dismantling operations or in pipe-laying and sewer construction, a competent well-established team is an important prerequisite for economical and prompt implementation of challenging projects. Another requirement is the use of efficient multi-purpose construction machinery and the appropriate working tools.
Dismantling
The application of more stringent legislation in respect of dismantling operations has led to increased demands on the tools implemented in this sector. Aside from traditional hydraulic hammers, depending on the type of dismantling job, demolition and sorter grabs, hydraulic cutters, demolition pincers, shears and pulverisers are also used. Targeted tool deployment thus permits economical and safe demolition of existing buildings and appropriate material sorting.
Pipe-laying and sewer construction
In the course of sewer construction drivers must repeatedly master various tasks in quick succession with their hydraulic excavators: excavation, foundation work, pipe-laying, sand back-filling, filling, lining and compacting. The use of a hydraulic excavator with a quick coupling system is essential for executing pipe-laying and sewer construction projects economically and competitively.
With its quick coupling systems and working tools Liebherr offers practical economical solutions for virtually all construction and dismantling operations. For increased productivity, efficiency and safety on the building site.

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 following 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.
Features and customer benefits
•straightforward sturdy design for a long service life and low maintenance costs
