(in combination with
LIKUFIX*)
Electrocontacts
(in combination with
LIKUFIX*)
Application - for earthmoving
- for rare tool changes
- for heavy applications
(f. e. tunnel application)
- for frequent tool
changes
(mainly mechanic tools)
- for regular tool changes
- for canal construction,
civil engineering and
demolition
- 10 memory slots for
tool data (oil pressure
and oil flow) in the
hydraulic excavator
- automatic tool
recognition (transmis-
sion of all relevant tool
data to the excavator)
- 5 electro-contacts to
transmit signals be-
tween excavator and
working tool
Advantages
- maximum handling
performance
- best fuel efficiency
(tons per litre Diesel)
- simple technology
(only mechanic
components)
- low cost of purchase
- quick change of
mechanic tools
- no persons in
danger zone (change
of mechanic tools)
- easy retrofitting of
LIKUFIX
- quick change of
mechanic and
hydraulic tools
- no persons in danger
zone
- Fast manual setting of
the required tool data
(oil pressure and oil
volume) at the push of
a button
- easy analysis and post
calculation (tool work-
ing hours saved on tool
chip)
- shelter from accidental
misuse
- to control
electro-valves of
the working tool
- to transmit a
BUS-signal
(f. e. GPS-signal)
Disadvantages
- no flexibility
- safety hazard at tool
change by pins
- reduced lift capac-
ity due to additional
weight of quick coupler
- reduced lift capac-
ity due to additional
weight of quick coupler
- additional components
- reduced lift capac-
ity due to additional
weight of quick coupler
- additional components
- In case of incorrect
operation (selection
of incorrect tool data)
there will be restricted
performance and dan-
ger of damage to the
tool
