ABSTRACT:
A lifting apparatus for containers of a flowable material which comprises a base member, a first elongated tubular column, a second elongated tubular column, a container support, and a lifting and lowering assembly. The lifting and lowering assembly is housed interior of the second column and includes a reversible gear motor and an elongated lift bar. The gear motor selectively drives an endless flexible tension member by way of a drive member cooperating with a driven assembly. One end of the elongated lift bar is connected to a first segment of the flexible tension member. A distal end of the elongated lift bar is attached to a base assembly. The second elongated tubular column is selectively lifted or lowered with respect to the first tubular column, in telescopic fashion, as the flexible tension member is driven. The container support, which may have tilting capabilities, is attached to a moveable carriage member. The carriage member is attached to a second segment of the flexible tension member and is lifted or lowered at a selected rate simultaneously with the second elongated tubular column.
