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 com-
pactness. 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 modifi ed without moving the
machine.
The machine is also equipped with a telescopic arm
that provides additional reach. Work as close to the
work object as possible as this makes optimum use of
the power to the arm system and cylinders.
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 activat-
ed, the function is braked by means of passive brakes.
NB! The machine’s rotating function must not be sub-
ject to overload, e.g. caused by tools that exceed the
weight limit.
Caterpillar tracks
The caterpillar tracks are driven individually by hydrau-
lic 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 oper-
ated in confi ned 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 fi tted with tools that are ap-
propriate 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 (optional)
The machine has been prepared with connections
for external hand tools for the machine’s hydraulic
system.
