The output is up to sixteen times that achieved by conventional excavation. Buried pipe systems do not suffer damage. Suction excavators eliminate the need for costly and time-consuming manual labour.

Operations involving the use of horizontal boring units.

Cleaning blocked street gutters and gullies.

Removal of material in demolition projects.

Replacement of contaminated soil around the roots of trees.

Railway trackside maintenance and repair.

Renovation and new installation of gas, water or heating pipes, cables, and sewage lines.

When it is emptying its load, the spoil tank lid (with the hose connection) hinges off to the right, and then the spoil tank (with the filters) tips about 90° over to the left to tip out its load. The suction unit is roughly rectangular-block-shaped, about 2.5 meters wide and 3.6 meters high, and is usually mounted and used on the back of a truck, which must have power takeoffs to run the suction unit's air impeller and hydraulics. Inner-city excavations in confined spaces Since 1993 RSP have produced suction superstructures mounted onto two, three and four-axle vehicles, stationary suction units as well as custom-made machines. It is said to have a newly designed air flow principle, and thus a considerably improved suction performance compared to MTS's previous designs.ĭesign and operation RSP Since 1998, the Mobile Tiefbau Saugsysteme has produced another type of suction excavator. These vehicles work with the internationally patented suction principle which guarantees the highest degree of gravity separation, lowest contamination of the filters, and thus consistently high suction performance. Since 2000, RSP developed a new suction principle, the ESE series. RSP has been making suction excavators and stationary suction units since 1993. No manual hand tooling is used in the process. Compressed air is used to fracture the ground for the suction excavator to remove the material safely. Then, the suction excavator hose removes materials below the surface. First, a small surface area hole of about 10 inches (250 mm) is created. Suction excavation utilizes high-powered fans to safely excavate up to 141 feet (43 meters) of depth depending on the configuration.
