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 modiÞed 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 conÞned 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 Þtted 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.
