Cutting even surfaces and stable embankments
When cutting, the 260 SX(i) cross application miner produces precise, even surfaces that can be used directly afterwards as access roads for vehicles on the construction site. On the one hand, for example, existing profiles copied via side plate scanning can serve as a reference for levelling. On the other hand, new profiling is also possible with the 260 SX(i) 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 road bed for subsequent paving. During the cutting process, the machine enables the production of stable embankments with a predefined slope 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 during ongoing rail traffic. Blasting is seldom a viable option for loosening the rock. The 260 SX(i) cross application miner enables the precise removal of benches with minimal vibration and the lowering of the tunnel profile to the desired level. The overall 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) from Wirtgen can also realise its full performance potential in narrow tunnel systems.
