Most experts maintain that, while there are newer methods, a Sewer Equipment CO. of America bucket machine is the preferred method for cleaning larger lines that are heavily laden with sediment. Our process allows for a clamshell bucket to be pulled into the pipe with the pull-in module until the bucket is full. Once full, the truck loader module pulls the bucket back out of the line by way of a cable, therefore closing the clamshell and the material can be deposited into a truck. This process is repeated until the line is clean. Bucket machines hold many advantages: no water is required for operation and only solids are hauled by the bucket, which allows for large lines to be cleaned more quickly and effectively than with a combination truck. Bucket machines are also an excellent clean up tool in the event of a petroleum or chemical spill, as no water is added to the material during cleaning, thus saving an disposal costs. The PULL-IN and TRUCK LOADER are available to be purchased separately.
