UNAC RAIL 300RR ROAD-RAIL MULCHING VEHICLE MANUFACTURER OF HEAVY DUTY TRENCHERS • FORESTRY MULCHING VEHICLES • MILITARY DOZERS • ROAD-RAIL SYSTEMS • SNOW CLEARERS Purpose The 300RR permits to achieve mulching of sides of railroads directly from the rail tracks. It uses its great range to effectively mulch around rails, in road beds, in trenches and on slopes straight from the track. Description The 300RR is a self-propelled vehicle with hydrostatic drive. On the road, the carrier can move in “crab” mode or with coordinated wheels in order to make easier manoeuvring and moving onto the rails. On rails, the machine moves thanks to a direct hydrostatic drive, that does not involve any direct contact with the tyres, for precise movements of up to 30 km/h. This vehicle includes: • A mechanically welded support structure with high-elastic resistance boxed stainless steel side rails on which the axles that enable all-terrain motions are mounted, along with 4 driving and steering wheels, • Two teetering bogies that enable to pass over railway wheel sensors without detection, • An accurate swivelling hydraulic loader that can make the lateral movements required for mulching works, along with a dedicated mulching head, • A cab that can swivel up to 90°, providing full visibility of the work zone and upcoming rails, • High railway safety level equipment, approved to work where adjacent tracks are open to trafc. Strengths • Prevents having to use other mulching vehicles that represent risks, being too close to the tracks and leaving residue on the tracks or even on the trains, • Can access worksites that are impossible to access for traditional machines that use tyres or caterpillar tracks, • Can move in both directions on the track, • Uses a very secure and ergonomic system, which satises the most stringent railroad standards, authorizing work under live overhead wires or where there is an adjacent track that is open to train trafc, • Ergonomic controls and a comfortable, soundproof and air conditioned cab, • Mulching head that is quick and easy to interchange (possibility of using a rotary slasher/mulcher), • Can also be used on roads, • Powerful mulching head and long-range crane, • Has an anti-infringing mechanism of the adjacent track for use during the process of setting on/off of the track, • Uses teetering bogies with inverted wheel anges to enable working without triggering the rail wheel sensors that are on railroad networks during the repetitive forward and backward movements, • Derived from UNAC’s successful experience in building forest mulchers and railroad vehicles, • A proven system that already has over 40 machines in service in Europe. www.unac.fr Avenue de Camargue • Zone Industrielle B.P. 9 - 30310 VERGÈZE - FRANCE T. +33 (0)4 66 35 02 53 • F. +33 (0)4 66 35 09 32 • info@unac.fr
