What a bazaar looking contraption!
Hello Arly,
When MArtin Beilhack patented his first railway snow clearer in 1952
he accomplished a world changing method of snow removal on railroads.
As of today there are at least 53 of these Railway snow clearers used worldwide
most of them are in europe and have replaced almost all of the rotary snow plows
that have been in use. The few that are left are museum pieces that may be brought
out on occasion and a couple more rotary plows in the old eastern block countries.
In the first image the HB1600S model has the moldboards fully extended outward
and the discharge chutes pointed to the full left position and full right position.
The chutes can also discharge the snow forward with these chutes and spouts.
There are two gear driven snow and ice breaking propellers in front of the discharge chutes.
They spin to break up deep snowpack as the as the snow and ice breaking propellers mounted in front of the snow
clearing discs on extendable arms that rotate at the same high rate of speed breaking the snow and ice
into the smallest portion. This allows the 4 scoops on each snow clearing disc which are rotating in
opposite directions to scoop up the broken snow and ice and throw it up and out of the chute and spout
at high speed and volume as shown in image 11380. In images 68129 and 68126 you can see the snow
clearing heads have been moved outward with the double acting slide cylinders to clear the right of way to the full
fifteen foot width.
Here are few photo images to show you how the snow clearing heads work with them fully extended.
