Abstract: The large bale handling apparatus comprises a wheeled flat bed trailer, and a rotatable articulating arm with a bale lifting mechanism rotatably and pivotally attached thereto. The bale lifting mechanism may be a lifting fork attachment for lifting large round bales or a rectangular bale attachment for lifting large rectangular bales.

Abstract: Self-loading/unloading transport trailers include at least one rearwardly extending frame extension foot which is positioned below a rearward cross-brace of the cradle frame. During a loading/unloading operation, the rearwardly extending frame extension foot will engage the ground surface to cause the cradle member to pivot thereabout and physically lift the wheel assemblies out of ground-engagement. Continued pivotal movement of the cradle member about the ground-engaged frame extension foot will then allow the cross-brace to come into contact with the ground and will thereby cause the frame extension foot to become disengaged with, and the wheel assemblies to be further incrementally lifted above, the ground surface. A manually actuated mechanical brake assembly is provided in order to arrest rearward movement of the transport trailer during a loading/unloading operation and thereby allow the cradle frame to initially pivot about the journal axis of the wheel assemblies.

Abstract: The bin grabbing nipper (22) of a refuse loader arm is held at a constant angle to limb (15) by a parallelogram linkage having pivots (26, 17, 19, 25). Thus, pivoting of limb (15) leads directly to inversion of the raised bin and no separate operation of a special bin tilting ram is required to bring a bin to dumping position. The nipper consists of two opposed, jointed fingers which are separately pivoted to a wrist member (21). All finger joints and wrist joints of the nipper are pivoted by separate hydraulic cylinders supplied by a common source. By sensing back-pressure in each cylinder they can be made to exert equal force. Pivoting at limb joints (17) and (19) is by opposed hydraulic cylinders acting on a rack meshing with a gear wheel. Both these joints may be controlled by a single joystick.
