history

Before the new Xrot m 9216 was purchased, the RhB only had two steam snow blowers from the Bernina Railway , two mainline steam snow blowers and a small electric snow blower from the Bernina Railway and various track plows for clearing snow . In particular, the operation and maintenance of the steam snow blowers was very cost-intensive. A new way of clearing snow was therefore sought.

There were two companies to choose from for developing and manufacturing the vehicles . On the one hand, this was Rolba , who propagated a system with hobbing, and on the other, Beilhack, who offered a system with spur gears. The Leslie system used in the steam snow blowers was not available because it requires very high thrust. The snow blower was ultimately built by Robert Aebi (RACO) in Regensdorf, with the blower unit being supplied by the Beilhack company from Rosenheim.

When purchasing this new type of snow blower, it was believed that it would be efficient to use a small snow blower to regularly throw away the snow walls on both sides of the tracks that were piled up by the track plows. The advantages of this type are that a track plow is the cheapest way of clearing snow before regular trains, and that a small snow thrower is sufficient to remove the accumulated snow walls through regular use.

construction

During the development phase, Beilhack came up with the idea of ​​laterally extendable blower wheels and thus variable widths. At the RhB, this idea was viewed with skepticism at the beginning, as there were doubts about the mechanical stability of this construction. Today this type of construction with side-extending blower wheels is widespread. Despite the modest output of 220 kW, it has a centrifugal volume of up to 3,000 t / h at a height of 1.94 m and a maximum width of 4 m.

The snow blower can be rotated 180 ° on its bogie . The full power of the diesel engine is used to drive the centrifugal wheels, so it has to be pushed by an additional motor vehicle .

commitment

Due to its extremely small size, compared to the steam snow blower, it was immediately given the nickname "Schleuderina". It was not suitable for large amounts of snow after a heavy snowfall or avalanche, but with its clearance width of up to 4 m it showed its strengths when removing piled-up walls. Despite the successful use, it remained the only one of its kind. At the beginning she took over most of the snow removal on the north side of the Albula . Today she is stationed in the Chur Sand depot and takes over the snow removal on the Arosa line .

History

After the opening of the Vereina tunnel in 1999, there was a shortage of snow removal equipment at the RhB in the winter months to clear the two loading portals. The Swiss company Zaugg AG in Eggiwil was then commissioned to build a centrifugal unit. The finished centrifugal unit was then attached to the substructure of the broken off freight car Gbk-v 5606 (built in 1913) at the RhB .

The Xrot m was given the number 9214 with a second line-up after the Bernina steam snow blower already owned it as the Xrot d 9214.

commitment

In winter the snow blower is stationed in Davos Platz and is mainly used to clear the Vereina loading portals. The clearing capacity is 5000 t / h.
