ABSTRACT
Trash rakes are heavy duty raking devices that are used to remove large or rough debris retained on a trash rack. A trash rake consists of one or more stationary trash rakes and a screen raking mechanism. The trash rake design uses a single, toothed rake that is raised and lowered by means of one or more sets of stainless steel cables to clean a stationary trash rack. Tooth opening and closing are accomplished by changing the effective cable length. The guided rake design is recommended for vertical trash racks or trash racks inclined less than ten degrees from vertical. The nonguided rake design allows the rake to rise over obstructions on the trash rake and is preferred for most trash rake installations. Trash rakes can be mounted on a self-propelled hoist frame capable of traversing the width of an entire intake.
