I see a mobile invention for the 'Shark Tank to invest in.
A flatbed with an adjustable bar which can swing out to either side as well as raise & lower according to roof heights.
Such as the hydraulic booms,on roofing,& concrete block supply trucks.
Could ride around to truck stops & trucking yards charging so much per unit to remove snow & ice.
Would have to be in partner with a snow plower to push the fallen snow out of the way.
There you go I have the idea,only thing is lacking at my end is the money.
