Walker - Segmented Plow Rake - Brochure

For greater flows and the resultant larger basins, higher torque capacities are required of the collector mechanism. A spur gear driven pier-supported collector is usually best applied in this class of service. Walker Process Type RS collectors are built around a center pier which supports the entire rotating portion of the machine plus half of the access bridge load. In addition to providing support, the pier resists the torque developed by the collector`s sludge plowing action.
