ABSTRACT:
A lifting mechanism for a sedimentation tank is provided for vertically raising and lowering a rake assembly in such sedimentation tank. The lifting mechanism comprises one or more elongate members pivotally connected to certain structural elements of the assemblage, such as the rotary drive motor, rake assembly, column or bridge. The pivotal connections of the elongate members are positioned about a horizontal axis and are oriented to receive the torque forces imposed on the assemblage as the rake assembly rotates in the tank simultaneously with vertical lifting. The torque forces are translated into the pivotal connections and are able to counteract those forces to facilitate vertically raising and lowering the rake assembly while it is being rotated in the sedimentation tank.
