Trash rake system for clearing intake racks and the like
A powered trash rake system for clearing debris from intake racks used for screening debris from water intakes and other similar structures. The trash rake system includes a telescoping boom mounted to a movable carriage support structure. Electric motors are provided to move the carriage support structure to desired positions along the intake rack to be cleaned and to operate the telescoping boom to move a trash rake structure under power vertically along the trash rack to remove debris therefrom.

A protective sleeve for use with metal intake racks used for screening debris from water intakes and other similar structures. The proactive sleeve may be made from a plastic material, such as HDPE, using an extrusion process. The sleeve is designed to snap into place over the metal blades of a bar rack, and to provide a positive and secure fit when in place. The protective sleeve thus provides the benefits of non-metallic intake racks to existing and future metal rack systems, without requiring replacement of existing metal racks.
