Hydrorake Systems - Single Boom ST8000

The Atlas Polar trash raking system cleans any gauge screen or bar rack. Installation upstream provides space for trash removal and deck access for personnel. The fully automatic system replaces handraking, which is still the most common method of rack maintenance. The Hydrorake imitates this action automatically 24 hours a day even in the coldest weather. The PLC control system permits tailoring the operational sequencing to any flow or debris conditions at each intake. Multiple units can be used on the small rail system for intakes with large masses of debris such as the USBR fish screen protection barrier in central Washington state. How the Atlas Polar ST8000 Hydrorake System works 1. A telescopic boom with rake head extends into the water by means of a hydraulic/ mechanical boom system. 2. A hydraulic cylinder tilts the boom to hold the rake against the racks at a constant pressure while a second cylinder lifts the boom. 3. When the rake reaches the top of the racks it automatically dumps the debris into a spillway that runs the length of the intake. 4. The optional transporter/spillway system then moves the debris to a collection area on either side of the intake.
