Claims (1)

[Scope of utility model registration request] A back-and-forth movable table that can move forward and backward, a left-right move table that can move left and right, and a rotatable rotary table are stacked on top of a base table that moves up and down. The return to the origin is carried out by protruding a cylinder rod provided on the table or another table directly below the table by a set amount and bringing it into contact with an abutment member provided on the other table or the table that moves back and forth or moves left and right. By doing this, the rotation table is returned to its origin by the rotation mechanism until the limit switch provided on the other table or the rotation table is operated by the actuating member provided on the table or another table directly below the table. A heavy object loading device characterized by performing this by rotating a rotary table.
