Once the hopper is full of debris, most international sweepers unload material right on the ground (usually in high-density, high-traffic areas), then later, both time and money is spent to pick up this same material. This is a very inefficient practice. That’s why almost all road sweepers in North America are able to unload debris into a dump trucks or containers. The most efficient unloading system is a high dump system that unloads to the side of the sweeper, this allows you to unload material at the sweeping site even when there is traffic.
- The high-dump hopper allows you to dump into a variety of trucks and bins. This eliminates trips to the landfill, reducing driving time and increasing time spent sweeping.
- The idea of increasing hopper capacity to increase sweeping efficiency doesn’t hold true because you are then forced to use a larger truck and this results in more fuel consumption, higher costs, and larger turning radius.
- While sweeping in high traffic areas, side dump allows you to unload the hopper at the work site by having the dump truck pull up alongside the sweepers driver side. This results in minimal traffic holdup and because the sweeper never has to leave the curbside, the operator can get back to sweeping within minutes.
- Side dump allows the operator of the sweeper to have eye contact with the dump truck operator, increasing communication and reducing accidents.
