Heat and Controls truck dumper quickly and safely unloads potatoes, root crops, fruits and vegetables by tilting trailers to a 45° angle. Gravity does the work, eliminating damage and labor costs resulting from traditional mechanical and manual unloading methods. A hydraulic metering gate controls product flow from the trailer. Tire guide rails help drivers quickly position tractors with trailers up to 70 feet long. Requiring no excavation, the truck dumper can be ready for use in one day and is provided as a complete system including hydraulic pumps, filter, motors and operating controls.
