ABSTRACT:
A retractable traversing trash rake is provided for cleaning weedscreens or bar grates at an installation for generating power, filtering water, or the like. The trash rake includes a frame carrying a troney movable from a position inside the frame to a position outside the frame. The trolley carries a trash rake which may be lowered to clean the weedscreen, and the trolley may be moved to a position within the frame, where the trash rake may be opened to deposit collected debris into a hopper. The hopper is pivotally mounted for tilting in opposite direction to provide multiple dumping options. A method of cleaning weedscreen by using a retractable traversing trash rake is also disclosed.
