Tow plow attachments are 26 ft lengthy, however deployed at a 33 % angle, it might plow 14 ft of a roadway. With the truck and its 12 ft of blades, which may cowl 9 ft to 10 ft of a roadway, the 2 mixed can cowl a whole 24 ft or one aspect of an interstate or a two-lane street with wider shoulders.
North Dakota has 32 tow plows along with its 350 snow plows to assault state highways and interstates, stated Mike Kisse, program supervisor for the state Division of Transportation upkeep division in Bismarck.
Of these 32, sixteen are bidirectional and sixteen are proper-handed.
They usually aren’t low cost.
Every bidirectional plow, which could be moved in both path relying on the wind, prices $one hundred forty,000, whereas the suitable-hand plows are $one hundred fifteen,000.
The added plowing capability might help reduce down on the period of time and plows wanted to clear roads, including as much as some value financial savings.
One benefit is that a 2,000-gallon tank carrying a liquid de-icer may be hooked up to a tow plow. The state makes use of a mix of salt brine and beet juice.
Kisse stated the tank can apply the de-icer concurrently plowing is happening if the circumstances name for it. In any other case, it may be used individually.
Yet one more benefit of the plow is that it may well journey as much as fifty five mph, which will help minimize down on the quantity of people that might need to attempt to cross.
There isn’t any assure of that, although, Kissee admitted.
He urged motorists to maintain their distance, and steered they keep properly behind the huge plows, which typically pull over in a protected place to permit backed-up visitors to cross.
When circumstances are poor, most drivers can be higher off staying behind the plows, he stated.
The bigger tow plows can scale back visibility greater than a daily plow due to its measurement and it is troublesome for the plow operator to see, though they do have cameras that permit them to see behind them.
What’s extra of an issue is that if the snow plow shoots up a snow cloud, making visibility for motorists behind or making an attempt to move virtually unattainable.
Tow plows come from just one firm within the U.S.—the Viking-Cives Co. in Morley, Mo., the place a former state division of transportation employee dreamed up and patented the tow plow, Kisse stated.
