Special equipment optimises the range of services
As an addition to the RSRG fleet of excavating machines in standard gauge, the ITC-1 has been available since this year. Originally built for the British market, the machine returned to Switzerland at the end of 2020 and was successfully overhauled in the spring of 2021.
The ITC-1 is a road-rail excavation machine and is based on ITC tunnel excavators. For excavation (ballast, PSS) to a depth of 1.2 metres, the machine has a swivelling excavator arm with Rototilt. Conveying and loading is carried out by a scraper belt on the machine and an additional, approx. nine metre long transfer belt (40° swivel to each side). This means that longitudinal loading in the working direction as well as transverse loading onto the adjacent track are possible without any problems. The ITC-1 can move independently on caterpillar or track. One axle is hydrostatically driven for travel on track. It has four-wheel braking on both axles. All moving components on the track are doubly secured in their parking position, monitored by the integrated PLC control to SIL-2. Work (excavation, loading) is carried out exclusively on the caterpillars.
Transport to the entry point of the construction site is by HGV. The machine then can be driven on the track to the excavation point. Depending on the construction site, the excavated material can be loaded into the downstream MFS+/AVES or by transverse loading into ballast trains, dumpers or HGV’s. Spray nozzles are available to reduce dust. Leica 3D monitoring is retrofitted to ensure the correct excavation level.
In June 2021, the ITC-1 made a good impression on the first construction sites in Switzerland.
