Abstract

A washing and recycling unit for on-site washing of heavy machinery. The unit has a supporting frame onto which is mounted a washing liquid storage tank. A washing hose arrangement connected to the tank injects washing liquid over the heavy machinery. A drainage receptacle positioned under the heavy machinery collects used liquid mixture falling from the heavy machinery. The used liquid mixture is sucked up with a suction hose connected to a cyclone which separates rough solids from liquids. A pump and filtering arrangement recycles liquid from a settling tank under the cyclone by pumping it out, filtering it and transferring it into the washing liquid storage tank. A hoisting system mounted onto the supporting frame is used to movably support an operator directing the washing liquid around the heavy machinery.
