A rotary cam load positioning apparatus has a base, a bottom cam rotatably mounted on the base, and a top cam rotatably mounted on the bottom cam. The rotary cams have cylindrical wedge-shaped configurations with respective upper and lower surfaces disposed in inclined relation to one another. Thus, rotation of the top cam relative to the bottom cam will produce a change in the elevation position of a load supported on the upper surface of the top cam relative to the base, whereas rotation of both top and bottom cams together will produce a change in the azimuth position of the load supported on the upper surface of the top cam relative to the base.

A load supporting and positioning apparatus, comprising: (a) a base; (b) a bottom cam rotatably mounted on said base and having upper and lower surfaces disposed in inclined relation to one another; (c) a top cam rotatably mounted on said bottom cam and having upper and lower surfaces disposed in inclined relation to one another such that rotation of said top cam relative to said bottom cam will produce a change in the elevation position of a load supported on said upper surface of said top cam relative to said base, whereas rotation of both top and bottom cams together will produce a change in the azimuth position of the load supported on the upper surface of said top cam relative to said base; and (d) an intercam latch mounted on one of said cams and being actuatable between operative and inoperative positions for latching with and unlatching from the other cam such that said cams can rotate together when said intercam latch is in said operative position and move relative to one another when said intercam latch is in said inoperative position.
