Snow depot machines

In larger Canadian cities like here in Montreal, the streets are cleared by large city snowblowers that put the snow in dump trucks, which then bring their load to snow depots. These are large vacant lots where the snow is then piled high and allowed to melt well into the summer months. Some of these piles are over 100 feet high. To pile it that high, there are special high power snowblowers designed for that purpose. They are designed as attachments to a loader and have their own engines. The spec sheet for the Larue D-97 in the pic below mentions that it has over 1000 hp and can throw snow up to 180 feet away. These beasts are built in Quebec city.

I wonder how fast the impeller spins to be able to throw the snow 180ft with that short chute (short in relation to the impeller size).
But most importantly what is the impeller tip speed and its diameter?

Impressive! Imagine that thing consuming a shopping cart or deer carcass.

The spec sheet doesn't mention impeller speed, but here is the full page on it:

Loader mounted snowblower D97 - - - J.A. Larue

Hmm, I could just picture one of these in a Mad Max movie someday... like a couple of bad guys on motorcycles meet their fate in that bucket.

A number of early snowblowers had that design, no auger just a large impeller, wonder why they abandoned it?

You mean like this...



Homko and Craftsman are the two I know were like that, although I think I saw somewhere an Ariens very early snowblower design kind of like it....

But if you browse at the following link, You'll find more makers of the "fan only" style blowers.
The Gilson Snowblower Shop's Vintage Machine Showcase

My guess for the change in design perhaps was safety regulations..... and/or efficiency.....

This is what I saw for an early Ariens......

Ariens Snow Blowers



The Great Depression had only been underway for a few years when an idea was sparked in 1933. Henry Ariens’s company, Brillion Iron Works, the one he had spent 40 years building, was gone in an instant. But instead of giving up and rolling over, Ariens and his three sons turned their focus elsewhere.
Using a $1,500 loan borrowed against his life insurance policy and another $1,500 raised by selling stock shares, the four Ariens built what would eventually become one of America’s premier snow blower companies, starting with America’s first man-made rotary tiller.
And now, 80 years later, winter weather dwellers everywhere are as familiar with an Ariens snow blower as they are with the season itself.

Or how about the limited width that can be cleared without needing a huge impeller? Railroads don't need to clear a huge swath and they still do use the rotary design:
