  • Patent number: 9210843
    Abstract: A fork-type dual bale lift has both longitudinal and machinery pivots. A frame structure is mounted on a vertically swinging load support. A boom member is coupled to the frame structure through a pair of bearings and is pivotal about the longitudinal machine axis. At the ends of the boom member are bale supports that are operative to pierce and support a large bale for lifting and transport. A hydraulic cylinder is used to control the pivotal orientation of the boom about the longitudinal machine axis, and thereby allow an operator to selective raise one of the two bale supports while simultaneously lowering the other of the two bale supports. At the extremes of boom rotation, the lower of the two bale supports additionally engages with the frame structure to provide increased strength and stability during loading and unloading, and to reduce stress on the bearings during transport.
