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? :blush:
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.... :blush:
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.
Another issue is getting a large (thus heavy) impeller to spin at high speed requires a lot of power, easily slowed down by getting bogged down into thicker snow. Having much slower, geared down augers allows for greater torque in breaking up the snow (especially if it's been plowed and packed) and then bring the snow to a smaller impeller makes for a lower power engine still able to throw the snow at a good distance.
RE: Fan Only Snow Throwers
We had an old Eska "Sno-Flyr" that my Dad bought from W.T. Grant and I don't remember the engine being excessively loud, but the drivetrain to get that auger to spin fast was. I could be wrong but I think it spun all the time and you didn't want to get anywhere near the front of that thing.
Oswego, NY has several snow stockpiles in the city limits every year. The last couple of years they have melted back to the ground and they have not had to push the pile back to have room for more snow in the summer months to have more room when the fuzzy stuff starts flying.
Northern Japan has many snow stock piles and they have at least one snow melting station and foolishly l I did not save the URL for the Video.
The snow melting station/pit is wide enough for five of there small dump trucks to dump at once and the melt water in the melting pit is so hot it is steaming at all times quickly melting each truck load of snow.
Perhaps Yanmar Ronin San knows which one I am thinking about??
