The belt unloader eliminates tipping overs, because it does not have to be tipped to unload the materials. The belt unloader has a lower center of gravity, making it easy to unload in an uneven area, compared to tippers that have to stand on a flat surface to unload. Overhanging road markings or power wires present a danger to the conventional tipper during unloading, but with a DO-WA belt unloader, wires and signs are no problem. The belt trailer can work anywhere it can drive, from viaducts and tunnels to low buildings and under trees.


The belt unloader is driven by a hydraulic system. When the driver engages the hydraulic system of the truck, the conveyor belt is activated so that the load is moved or unloaded horizontally outwards or backwards. The belt can turn both sides so that it can be loaded also for, for example, pallets or big bags.

What is a Live Floor System?

A belt unloader is a semi-trailer that is used for the transport of loose material such as asphalt, grain, potatoes, sand and gravel. A belt unloader is the alternative to a tipper or a tipper trailer. The typical belt unloader has a conveyor belt at the bottom of the bucket that unloads the material from the rear of the trailer at a controlled rate. Unlike the conventional tipper, the bucket does not need to be tipped up to unload the materials.


Belt unloaders can transport a variety of products, including gravel, potatoes, top soil, grain, roots, sand, lime, peat moss, asphalt, compost, soil, clay, etc. Ideal for those working in industries such as agriculture, infrastructure and waste take advantage of the versatility of these trucks or trailers.


The belt unloader will discharge clean empty, making it easier to transport different materials without having to clean the bin afterwards and have the risk on contamination.

The conveyor belt ensures that the material can be unloaded at a controlled and dosed rate, so that the material can be partially unloaded only where it is needed. The wide belt version has a lower center of gravity, which ensures a smoother ride and better road handling than other trailers. Working in tunnels, under bridges and in confined spaces is easier with a belt unloading than with a tipper, because it fits wherever it can go. Wet or dry, all materials can be transported in a trailer with a DO-WA belt unloading system.

In a tipper, wet materials stick in the corners and side walls during unloading and ensure that the trailer can tip over. The insurance costs are lower for a trailer with a belt unloader, because it does not have to be tipped and there are minimal cases where the trailer is tilted.
