ABSTRACT:
A portable anchor device for resisting the reaction forces associated with conveyance of a load between horizontal surfaces with different elevations includes at least one beam member with at least one support member pivotably attached at its upper end. The pivotal angle is selectively fixed so that the support member lies flat on the upper surface. A part or all of the load weight is supported on the anchor device and motive force is applied to the load by a winch secured to either the load or the anchor device. An anchor bar near the upper end of the anchor device projects above and behind the proximal edge of the upper surface. The anchor bar is pivotable to maintain collinearity between motive force and load advance. A flexible line which transmits the motive force from the winch to the load is anchored at the distal end of the anchor bar. A safety gate is disposed to prevent load descent until the flexible line is taut.
