![]() ![]() Mechanical broom machines may or may not be outfitted with a 'gutter broom' on one or both sides of the sweeper. ![]() The broom rotates in a clockwise fashion when viewed from the left side of the vehicle, and collected debris is swept onto some type of a conveyor belt for transfer to a containment hopper. Typically, these machines have a 'main broom' that runs transversely – from one side of the sweeper to the other – such that the broom bristles contact the paved surface the full width of the sweeper unit. Mechanical broom sweepers are still the primary machines in use by municipalities around the US. For years, mechanical broom sweepers were the only machines that were used for road sweeping by municipalities and departments of transportation. Mechanical broom sweeping technology may be likened to cleaning with a broom and a dustpan. And for pollutants such as zinc, which tend to become dissolved in water, there is not even any effective way to filter them out through sophisticated catch-basin or other stormwater filtration technology.įollowing are brief overviews of the major types of sweeping equipment available, as well as examples of usage and applicability: Mechanical Broom Sweepers are killed each year by pollutants attached to small-micron dust particles, and 1,000,000 more sustain serious lung impairment. According to EPA estimates, 30,000 people in the U.S. Either way, these particles pose an environmental challenge. Thats because with rainfall they tend to run off into stormwater systems as total suspended solids (TSS), or to get pounded into the air by passing cars (or blown into the air by wind) as fugitive dust (PM-10s). These small-micron particles are now seen to pose a significant environmental concern. A high level of increased emphasis, by the EPA and others, is now being placed upon the removal of small-micron debris as a Best Management Practice (BMP) for reducing stormwater runoff pollution. From an environmental standpoint, it is exactly this material that it is most important to remove. It has been confirmed that even though a street may look clean (before or after being swept), there still may be a significant loading of small-micron, pollution-laden debris on it. Thats because recent studies have shown that more than 50% of heavy metals and other serious pollutants are attached to particles that are 60 microns in size and smaller (as a comparison, a human hair is about 70 microns in width), even though particles of this size compose a relatively insignificant amount of the total weight and volume of a typical sweepers hopper load. Environmental Protection Agency (EPA), as well as by public works professionals and others throughout the country. ![]() Today, however, this reason for sweeping is undergoing significant re-appraisal by the U.S. It has been so-called because of consensus that if a street looked clean, it was clean. Since its inception, sweeping has been used to remove what might be termed cosmetic or political debris from roadways and other paved surfaces. The information in this article was last updated in December of 2010 First, a brief overview is provided of some of the emerging concerns in the sweeping industry. and international sweeping industry professionals in reaching a better understanding of the differences between the major types of sweeping equipment being used in the American road sweeping marketplace. Call us today and speak with one of our expert staff for details.An Overview of Sweeping Equipment TechnologyĪn Overview of Power Sweeping Equipment Technology This sweeping industry informational white paper is a collaboration between Ranger Kidwell-Ross, Editor of, and Roger Sutherland, Vice-President of Pacific Water Resources, Inc. No matter what the job, Smith Equipment can manufacturer a sweeper brush for you. Sweeper brushes are replaced according to several factors such as operator experience, amount of down force applied, and environmental conditions. Sweeper brushes are normally rotated on a type of automatic mandrel located near the ground level of the sweeper vehicle. Main Brushes and Tube Brooms are interchangeable terms and usually refer to the same type of sweeper brush. Known as coil spacing, this describes the gap between each piece of channel on the tube brooms. High density sweeper brushes use the same material, but are more tightly wound and don't have any spacing between the channels. Sweeper brushes can be wound with certain spacing for varying bristle densities. These bristles and wires are forced into steel channel that is pressed and welded onto the broom core. Tube brooms are industrial brushes with a cylindrical steel core that has polypropylene bristles, steel wire, or a combination of both. A sweeper brush or tube broom can come with a large variety of options. ![]()
