Each bogie has a bearing pivot and a frame attached to the lower end of the load with two co-operating bearing bosses, one at the lower corner and one at the center line of the load. During the first part of the lifting movement, the load rocks on the corner pivot and before it reaches the vertical the bearing elements on the center line engage.
