Tool Control
Tool Control is an additional electro-hydraulic function
that simplifies work with hydraulic working tools: up to 10
combinations of fluid quantity and pressure can be stored
with the tool name, and directly selected via the display unit
with touch screen function. With Tool Control the machine
operator can easily select the parameters for the required
hydraulic tool at the touch of a button – with no compli-
cated re-setting for a tool change. This function is already
featured as standard on most hydraulic excavators.
Tool Management (Option)
Tool Management enables automatic tool recognition by the
hydraulic excavator. The data stored on the chip in the work-
ing tool are read out by the read/write head in the LIKUFIX
coupling block on the hydraulic excavator, and transmitted
to the operator’s control console. The operator acknowl-
edges data at the touch of a button, thus ensuring automatic
adjustment of the fluid quantity and pressure. Aside from
this technical data, fluid type and the hours worked with this
tool are saved on the chip.
Electro contacts (Option)
Five electro contacts guarantee signal transmission between the hydraulic excavator and the
working tool. They enable controlling of electro valves in a working tool for triggering various
hydraulic functions and transmitting signals from a position transmitter/GPS receiver to a
working tool. The contact pins are spring-mounted and designed for heavy-duty building site
implementation.
