Snow Removal Being Enforced In New Hampshire

This one still works even though it snapped

 

Can be pieced together... "The Multi Use Snow Tool pulls apart and folds to a compact easy to store size to fit in your cab."

 

Snow rake might get the powder snow off but it will be useless on “frozen snow” that has become hard, and less than useless on any ice sheets that may exist. And it’s the ice sheet that is the dangerous part.

Getting snow removed IMMEDIATELY after it snows, off of every trailer, is just not feasible in most situations.

 

Powder doesn't turn to frozen slush unless you leave it up there while it rains. It has to be removed before the roof caves in, like people are advised to do with buildings (the reason snow rakes exist).

 

Actually, all you need is a little direct sunlight. Direct sunlight will melt ice well below +15f especially if it’s midday sunlight with less reflective effect.

Skiers hate snow with a crusty top layer. And this doesn’t happen due to rain.

 

You can be impossible about it for the sake of argument, if you want to say one method has to work for every situation imaginable (or snow removal has to be all or nothing). I don't really care, because it's an absurd argument to that end. Like saying you won't be having visible lights or reflective tape, because it's snowing, and you can't just stop and clean a whole fleet of trucks off with your mittens, before you'd have to find a scraper (two days later). Well, people in Minnesota couldn't stay on top of it enough to save their last covered bridge either (and probably had more than a day to prevent it)...

But how would you like having to go through it, when snow accumulation is nearing that point? I'll have to take a look at the roofs before I walk into buildings after a snow, for that matter (it seems they were collapsing all over the place this year). So obviously the point is that the more snow is allowed accumulate, which later gets saturated with water, the heavier and more dangerous it becomes (so whatever you can take off is helping to prevent some or all of this cumulative effect). Whether or not they collapse, top heaviness isn't good for maneuvering trailers especially (so there's another reason not to let hell freeze over here).

 

Deicing boots on the leading edge of aircraft wings are pneumatically operated. Trailers have an air supply readily available to inflate the boots, which would break the ice up. As someone mentioned, a curved roof would allow the ice to fall off. A side benefit of curved roofs would be trailers being less susceptible to blowover.

I'm sure there are at least a few reasons why this idea is impractical: the initial cost, the need for repairs (forklift driver putting a hole in the roof, hail damage, sun) and eventual replacement, and weight. As on aircraft, the boots can be divided into sections with multiple air lines so one damaged section wouldn't necessitate replacing the boot for the whole roof.

 

I don’t know how you could keep the rubber tight during hot days. And they might be susceptible to getting damaged from trees and become useless.

But I was thinking some sort of “thick fabric” that would glue to the top skin. This special heavy duty fabric would drape over the edges slightly. The fabric would effectively absorb and wick melt-water out to the edges then drip off. And what didn’t wick off and froze would stick to the fabric and not get air underneath it and fly off.
