ABSTRACT:
An improved device is provided for lifting the drum of a concrete mixer vehicle, wherein the drum has an encircling ring structure. The device includes a body mechanism having a body side wall and an inverted cup with a cavity for receiving a jack, a clamp mechanism wherein a cleat lower wall thereof is slidably adjustable relative to a lower wall of the body mechanism such that a cleat side wall is adjustable toward and away from the body side wall to clamp the ring structure between the body side wall and the cleat side wall, and a stabilizing mechanism for stabilizing the body mechanism relative to the mixer vehicle drum. The device may also include an adapter configured to also be slidably adjustable relative to either the body side wall or the cleat side wall. The stabilizing mechanism, which includes a tongue operably attached to and extending outwardly from the body side wall, a tapped throughbore spaced near a distal end of the tongue, and an axially adjustable adjuster, is configured to operably provide at least a three-point support for the mixer vehicle drum, either by providing the cleat side wall with a concave upper surface for abutting engagement with the drum side wall or by transversely abutting two bolt heads against the ring structure. A method of lifting the mixer drum relative to the mixer vehicle is also provided.
