PRESENTATION
The machine’s functions
The machine’s functions are operated by means of interaction
between the hydraulic system, the electric system and the
control system.
A brief description of the machine’s functions follows below.
Arm system
The arm system is divided into three parts in order to provide
extensive movement, a long reach and compactness.
Expanding shafts minimize the risk of play in the joints.
By running cylinder 1 and cylinder 2 in parallel, the machine’s
reach can be modified without moving the machine.
Tower
The tower has unlimited rotation, which means that is
possible to work in several directions without having to move
the machine. The machine is equipped with a slew brake.
When the rotating function is not activated, the function is
braked by means of passive brakes.
Caterpillar tracks
The caterpillar tracks are driven individually by hydraulic
motors. The machine can be turned by operating the
caterpillar tracks at different speeds. Operating the tracks in
different directions enables the machine to make tight
manoeuvres. When the drive function is not activated the
passive brakes lock the drive motors.
In transport mode, the caterpillar tracks and tower can be
manoeuvred simultaneously. The function can be used, for
example, when the machine is being operated in confined
spaces.
Outriggers
The main function of the outriggers is to give the machine
stability. They must always be used when working with the
machine.
Tools
The machine should be fitted with tools that are appropriate
for the tasks that are to be carried out. The weight and
performance requirement of the tool is decisive in
ascertaining whether it is suitable for use with the machine.
Further information is available in the 'Tools” and 'Technical
data” chapters and the tool supplier’s instructions.
External tool
The machine has been prepared with connections for
external hand tools for the machine’s hydraulic system.
NOTICE! The machine’s rotating function must not be
subject to overload, e.g. caused by tools that exceed the
weight limit.
