Cabin

The cabin has a height of 2095 millimeters, the width of this structure is 2710 mm.

The cabin of the special equipment is decorated with materials with increased noise insulation, which cover the internal surfaces of its doors. Thanks to this, the operator servicing the excavator does not suffer from the noise it produces during operation. Thus, it can work in absolute comfort even when the work is relatively long-term.

The Komatsu RS200-8 operator's chair is equipped with armrests, its location can be adjusted, and this element can also be moved. In this case, the chair can be moved around the cabin together with the joysticks that control the cabin, as well as separately without joysticks.

Minimization of vibration reaching the operator is achieved through a spring-hydraulic mechanism of a multi-layer structure, as well as a sprung platform. It is allowed to install an air conditioner and a radio together with a radio inside the cabin.

The cabin is characterized by a relatively large window size and, accordingly, a significant glazing area. In this way, an increase in visibility is achieved for the person in the cockpit, making it easier for him to monitor what is happening from all sides around him.

Also, a sliding window is inserted into the doors and roof of the Komatsu PC200-8, which during operation the operator can lock in a certain position to ventilate the room. At the same time, when the windows are closed, the interior has very high airtightness, and dust will not get inside.

In addition, the cabin has a locking mechanism for various controls, including levers. With its help, it is ensured that a worker climbing into the cabin will not accidentally press one of the levers, starting any mechanism. The operator will need to disable this locking mechanism to begin operation.

Information for the operator in the cab is displayed on modern small-sized displays.
