This invention relates to a guiding assembly for maintaining a rotary drive assembly, such as is used in mining and/or fluid thickening operations, in a desired orientation while raising or lowering the drive assembly. The invention also relates to a rotary drive lifting assembly which contains such a guiding assembly. Typically these are used in liquid/solids sedimentation to raise and lower rotable rake arms which engage settled solids within the tank and move the solids to a tank bottom outlet. |
