ABSTRACT:
A lifting apparatus including a beam assembly, a lifter affixed to a surface of the beam assembly for lifting weighted objects toward or away from the beam assembly, a cable extending from the lifter, a first leg pivotally connected to one side of the lifter on the beam assembly and a second leg pivotally connected to an opposite side of the lifter on the beam assembly. The first and second legs are pivotally movable between a first position in parallel relationship to the beam assembly and a second position perpendicular to the beam assembly. Each of the first and second legs has a foot member affixed thereto opposite the beam assembly. The beam assembly includes a first beam member and a second beam member in spaced parallel relationship to the first beam member. Each of the first and second legs also includes a bracket member which is detachably affixed to the first and second beam members, a first leg portion pivotally connected to the bracket member and a second leg portion in telescoping relationship to the first leg portion. The distance between the legs is adjustable along the length of the beam assembly. The length of each of the legs is adjustable by extending or retracting one leg portion with respect to the other leg portion.
