The Suction Evacuator

RSP Gmbh in Germany have been making mobile vacuum evacuator units since 1993, adding a newly designed air flow principle which has increased suction performance and has made it a much easier and more proficient vacuum truck. These vacuum trucks are generally used on construction sites where they remove earth debris from a hole on land through a wide suction pipe that can reach up to one hundred meters per second. These specific vacuum trucks’ construction is like that of a gully emptier, except they have a wider and more powerful suction hose. This type of excavation is widely considered the best possible way for safely locating underground utilities.

The parts of this vacuum truck include a suction nozzle, which has two handles on it for an operator to hold. Usually these handles have a collar that rotates to release the suction, causing the nozzle to drop anything that it has picked up, but is too big to go up the tube. The tube can be “toothed,” which helps cut the earth when evacuating materials, but most of the time the debris is loosened with a compresses air lance or water jet.

Often, excavation reveals unknown utilities, saving lives, time and money for construction crews. Hydro excavation, which is excavation with a powerful water jet, lessens the risk of damaging utilities missed on the map; a common practice called “daylighting.” There are various uses to vacuum trucks for sale and their suction excavators, such as digging a swimming pool, and on a railway in order to suck old track ballasts off the track. An archaeological excavation is probably the one job where a vacuum truck suction excavator would not be the best tool. The powerful vacuum, along with the high-pressure water, would most likely affect the various precise holes, trenches and tunnels on the site.

The use of underground locating services through vacuum trucks and excavating suction vehicles have become the norm, and in most areas, is required by law. However, vacuum excavation does have its limitations, but because it so cost effective, it has become the preferred technology. In addition, through aggressive and thorough educational efforts, the safety of vacuum excavation is now being regulated in many states and local communities in order to succeed with one hundred percent accuracy.
