Every year the city administration in cities in Sweden and other countries, such as Russia, China, Canada and The United States, is overwhelmed by incoming snowstorms that paralyzes the city roads, and maintenance can not be remedied, due to the lack of capacity and and logistical problems.
Also aspects of emissions, noise and congestion does, that one would wish for a smaller number of truck’s related to snow removal work.
With fewer truck transports, a large part of the budget will be saved and added as a reserve, and instead, the big snowstorms, to convene a larger number of machines to work for greater efficiency. During normal years big money could be saved, since the proportion of trucks during the annual budget could be radically less.
CompIce Flatbed is a solution to the problems with snow removal.
Snow contain large amounts of air, which provides the high volume and low weight, which ultimately results in the trucks carrying capacity, are not fully utilized. The CompIce Flatbed compresses the air out of the snows to a state closer to the ice, with 85% space can be saved, and to increase the existing transport capacity by 850% at the same number of trucks.
The CompIce Flatbed is loaded with snow, as on a number of occasions during the filling of the loading surface is compressed down to 15% of its normal amount, and can thus carry 850% more snow on the truck, the medical evacuation of the snows. The energy cost of compressing the snow to ice, is a fraction of the energy needed for driving basically empty trucks, transporting largely 90% air.
The CompIce Flatbed is being built like a container, which is outfitted with a compression device and hydraulics. The CompIce Flatbed can then compress snow to ice before transport with almost any type of truck, demount-able flatbed or container capacity..
Compared with gravel trucks, you’d see today in the snow clearance fleet, it may be likely that a maximum of large container can be 1200% larger in capacity. It will thus save 11 trucks for each trip. Thus end the truck convoys in the city center, which basically carry air, at a cost of SEK 1800 per hour.
Snow turns to ice when the pressure of approximately 140 kg/cm. You can probably achieve great effect already around 110kg, but the capacity for pressures up to 160kg/cm should be, to have good functionality for ice blocks or similar in the snows, these can provide great friction, in the redistribution of snow mass, while compressing.

The loading position, Compression doors folded to the outside of the container.
Position of closing and compression.
Compression doors locked and the compression phase starts.
Compression performed, in this stage doors is reversed to the starting position along the sides, and continued loading occurs, until the container volume, or truck’s weight, determines that the CompIce should not be loaded further.
The platform rear part, can be opened, and through the door, the CompIce is unloaded at the appropriate location. The mechanism for this part of the function, is not depicted on this sketch. One can imagine an additional hydraulic device inside the CompIce, pushing the ice lump outside, without any tipping taking place, if so, more trucks is suitable for operating the CompIce Flatbed.
