The Snowcuber MK6

What's the innovation

Our extensive and innovative study led to the development of a snow compressor module that compresses snow by squeezing out the air, reducing the volume of the snow up to 66%; the Snowcuber. By compressing the snow, the volume is significantly reduced, making it feasible to use dump trucks to transport the snow to another location. By dumping the snow off location, it is no longer necessary to close any of the gates, with fewer delays and cancelled flights as a result.

Getting all sorts of snow to the compression module

Gathering the snow

Probably the biggest eyecatcher of the Snowcuber is the large conveyor screw at the front of the machine. Its primary purpose is to gather the snow and transport it towards the impeller. Snow that is transported by the conveyor screw will end up in the impeller which is basically an oversized snow pump. The sole purpose of the impeller is to launch the snow into the compression module and thereby increasing the static pressure. This pressure is required to prevent the snow from gliding down the compressor screw.

The principle

Changing the system

Currently two ramp hogs plow the snow on to a pile on the side of the stand. With the Snowcuber it is possible to use a single plow that create a windrow on the stand. Regarding the type and amount of snow, the Snowcuber can load and compress this snow directly in a dump truck.

As a consequence there are no piles on the apron that decrease stand capacity and form a safety issue. 

The amount of dump trucks can be decreased by at least a factor two due to compression and controlled loading. And no snow sticks at the walls of the dump truck due to the controlled loading, maintaining the volume of the dump truck during the snow event.

For example, two centimeter of fresh snow and sixteen cubic meter in total, might cover the stand. The Snowcuber may reduce this volume to less than four cubic meter of snow in the dump truck.

In contrary to the current technology the Snowcuber is capable to load the snow controlled in a dump truck. It can therefore make a ‘pyramid’ on top of the dump truck. The capacity of the dump truck is increased from 18 to more than 25 cubic meter.
