A spreader assembly includes a frame and first and second spreader arms each including a pair of parallel spaced-apart beam members. The beam members are equal in length to each other and to the frame and each beam member has vertically spaced-apart rails. The frame also includes first and second pairs of bearings disposed above the horizontal center and on one side of the vertical center of the frame and third and fourth pairs of bearings disposed below the horizontal center and on the other side of the vertical center of the frame. In addition, the first and third pairs of bearings are disposed on the frame closer to the vertical center than the second and fourth pairs of bearings and the second and third pairs of bearings are disposed closer to the horizontal center of the frame than first and fourth pairs. The spreader arms are positioned on the frame with the rails of the first arm engaging the first and second pairs of bearings and the rails of the second arm engaging the third and fourth pairs of bearings. In addition, means are provided for simultaneously moving the spreader arms on the frame in equal and opposite increments.
