ABSTRACT:
An apparatus for driving and lifting the rake assembly in a sedimentation basin. An annular hub is mounted on the main gear member, such hub having slot means through which vertical edges of a vertically-extending rectangular torque-plate are slidably affixed. Torque is transmitted from the gear member, through the hub slot means, to the torque plate and to the rake assembly which is attached generally at the bottom of the torque plate. Side loads (horizontal unbalanced rake loads) are transmitted from the vertical edges of the torque plate through the hub slots to the main gear bearing in the drive. Means is also provided attached to the torque-plate to move the torque-plate upwardly through the slot means so as to raise and lower the rake assembly.
