These coarse screens are designed to remove gross debris from deep channels in hard-to-access locations. The equipment consists of a stationary bar screen located at the bottom of the channel to capture debris. A channel recess is not required. The bar screen is attached by rails to the discharge apparatus located above the channel. A special Grab shovel picks up the debris at the bottom of the channel and transports it to discharge.
The shovel has rake teeth and operates in the manner of a reciprocating rake bar screen. The position of the rake is controlled by a rotary selector switch. A pivoting scraper dislodges the debris from the Grab screen above the operating floor at the discharge point. Debris can be deposited into a container, conveyor, washer compactor, etc . The Grab screen is raised and lowered by a stainless steel cable.
