As a commercial grain hauler I have used a variety of electric tarps and hoppers and the ROLTEC Electric Tarp and Hopper Conversions from Agri-Cover have defiantly worked the best. Everything about having these electric conversions on my semi trailer has been a benefit to me. It saves me a lot of time, increases safety by keeping me out of the way of farm machinery, and increases my tarp life by getting a good roll every time. It also provides less stress on my back and shoulders than using a crank handle. Farmers are working longer days and longer seasons, and by having electric on a trailer it isn’t being lazy – it is being smart. The best part is I have had no problems with it breaking down, not one. The ROLTEC Electric conversions have consistency, longevity, and the difference between it and others I have used is the ROLTEC works

Over a year ago I added ROLTEC Electric Tarp and Hopper Conversions to three of my semi trailers. Being a custom harvester I know the importance of efficient work and my drivers really like how easy they are to use. I did the installation myself and after I got the first one done the rest went on really fast. Using the wireless remote saves a lot of time, when pulling into the elevator I can open my tarp as I drive and it keeps the flow of traffic going. The guys working at the elevator really like being able to flip the switch on the receiver box to open the hoppers too.
