Abstract:
1. A lifting mechanism for lifting materials onto a structure comprising: a first elongated section having two sides and a winch lifting mechanism; a second section slidably mounted on one side of the first section for moving upward and downward with the winch lifting mechanism; roller guide members for engaging the first and second sections to allow the sliding of the second section on the said one side of the first section; a support frame mounted on the second section and having a material support that is pivotally connected to the support frame on the second section for securing materials on the said one side of the first section for lifting onto a structure; said material support being pivotally mounted on the said support frame on the second section so that the material support can be loaded with materials on said one side of the first and second sections and raised and can be rotated on the second section to an upper unloading position on the said other side of the first and second sections; a releasable lock for pivotally securing the material support on the support frame in a plurality of locked positions including in a lower secured loading position for lifting the material support to a raised position to the top of the first section on said one side of the first section for lifting materials with the lifting mechanism to the upper and raised position and then for releasing the said material support for pivoting the material support to a selected unloading position when in its raised to the upper position on the said other side of the first and second sections to position materials for removing and unloading materials onto a structure supporting the other side of the first section.
