A trash rake system with an articulated rake head assembly is provided. The trash rake system includes a main unit, a telescoping boom attached to the main unit, and a rake head assembly attached to an end of the telescoping boom. The rake head assembly includes a base frame, a drive arrangement mounted to the base frame, and a rake head mounted to the drive arrangement. The drive arrangement includes at least one gear arranged to mesh with a rack gear mounted to a rack which is in turn mounted between a fixed member and a movable member of the telescoping boom.
There is disclosed a trash rake system for use in clearing debris from an intake screen of an intake trash rack of a water intake port of a water use facility. The intake screen is configured to collect debris transported by water, for example, a river, to prevent the debris from entering the intake port of the water use facility. The trash rake system includes a track system, a movable support structure, a rack and pinion drive mechanism, and a controller configured to receive signals from an encoder on a drive motor and a proximity sensor system.

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.
