A safe working environment
The 260 SX(i) is fitted with a dust-proofed positive pressure operator’s cabin with a fresh air filtering system, which effectively prevents dust entering the operator’s workplace. Apart from the comfortable operator’s seat, the cabin also provides an extra seat for a trainer for safe practical training of inexperienced operators on the machine. The cabin also features an integrated, certified ROPS / FOPS system to ensure the protection of the operating personnel. When working at night, safe operation is assured by bright illumination of all relevant working areas on and around the machine. The high-powered lighting system of the 260 SX(i) comprises LED floodlights for the working areas, lamps on the discharge conveyor and brightly illuminated access ladders and walkways. The operator’s cabin with all-round glazing is swivel-mounted on the front left chassis column and provides a consistently optimal all-round view of the working area and the material loading procedure. An operating concept in line with the latest standards of ergonomics provides an ideal workspace that is an inviting aid to productive working with minimal stress and fatigue.
Cutting level surfaces and stable embankments
In the course of the cutting process, the 260 SX(i) produces precise, level surfaces that can be used directly as roads for construction vehicles or as foundations for routing work. On the one hand, existing profiles copied by scanning the level of an existing surface using sensors installed on the side plate can serve as a reference for levelling. On the other hand, new profiling is also possible with the cross application miner, for example, on the basis of a 3D terrain model. Depending on the application, construction work can begin as soon as the desired profile has been produced. In road construction, for example, the surface cut by the machine provides an ideal base for the subsequent paving of surface layers. During the cutting process, the machine enables the production of stable embankments with a predefined bank sloping angle – making another decisive contribution to safety and the minimisation of the need for additional excavation.
The construction of new tunnels or the lowering of the floors of existing tunnels often involves working in confined spaces and parallel to continuing rail traffic. Blasting is rarely a viable option for loosening the rock. The cross application miner enables the precise removal of floors with minimal vibration and the lowering of the tunnel profile to the desired level. The height of the miner can be reduced for working in tunnels by mounting the operator’s cabin directly above the front left track unit. In this configuration, the machine also works using the cut-to-ground method, without a discharge conveyor and conveyor frame. This means that the 260 SX(i) can also realise its full performance potential in narrow tunnelling situations.
