The amount of snow that needs to me moved off the roads in Swiss Alps is enormous. So are the machines that do it! It is a common practice in many countries that get a low of snow in the winter to put chains on the tires to be able to drive uphill, if you happen to live in the mountains. But look at the sizes of tires and the amount of chains on this humongous snow plow!
For us – Poles – it’s quite common to use chains on tires during winter. In some areas we even have special signs informing us that when snow on road it’s forbidden to enter without chains.
