Ladder hoists are ideal for hauling shingles or heavy tools up a ladder to the top of the roof. TranzVolt Cordless Ladder Hoist, developed by TranzSporter, is the first lift hoist of its kind. It sets up in under five minutes without the need for tools and operates using a wireless remote control and two 20 volt batteries. On a single charge, the TranzVolt can lift up to 6,000 sq. ft. of shingles onto a one-story roof. The TranzVolt laddervator sets up in 5 minutes and is made in the USA.
