Abstract: An auxiliary assembly for attachment to a truck bed, the truck bed having pivoting bale lift arms, and the truck bed further having a hydraulic ram powered bale arm actuator, the assembly including a cargo carrying frame, left and right releasably attachable and pivoting mounts for interconnecting the cargo carrier and distal ends of the bale lift arms, and a pair of cargo leveling arms pivotally mounted to span between and interconnect the truck bed and with the cargo carrier for simultaneous and substantially parallel leveling arm motion, the leveling arm motion stabilizing the cargo carrier during pivoting motions of the bale lift arms.

Abstract: The present invention relates to a wheeled shovel loader that comprises a boom (3) capable of pivoting about an axis (4) as well as loading shovel (13) that can be actuated by a tilting structure (11, 12). According to this invention, at least one additional arm (7) connecting the boom (3) and the loading shovel (13) is hinged so as to be capable of displacement in the same way as a parallel linkage or parallelogram on said arm (3) under the action of at least a first connecting rod (8) and at least a second connecting rod (9). The shovel loader of the present invention comprises means for controlling the displacement of the additional arm (7) according to the angular position of the boom (3) relative to its pivot axis (4), as well as means for maintaining the loading shovel (13) in a horizontal position.

Abstract: A device for the paraxial kinetic control of a boom that can be swivelled perpendicular to the rotatable platform of a mobile lifting machine wherein there is provided at least one coupling rocker which is pivotally mounted on the boom and provides a pivotal connection for a plurality of points of application of force, two points of application of force being linked to the platform of the lifting machine.

Abstract: A grapple operating mechanism (12) is attached to a vehicle (10), such as a front end loader, and includes a boom (26) rotatably attached to the vehicle (10) and a pipe and pole type grapple (11) attached to the other end of the boom (25). A boom actuating mechanism (29) is connected between the vehicle (10) and the boom (25) for moving the boom (25) relative to the vehicle (10) and a grapple actuating mechanism (33,35,36,37,38,40) is connected between the vehicle (10) and grapple to rotate the grapple (11) on the boom (25). The grapple actuating mechanism has one or more actuating cylinders (33) connected to a first set of arms (36) attached to the boom (25).

Abstract: An improvement in scrapper type vehicle, for handling junk cars and the like, having a frame mounted on wheels and having a prime mover powering the vehicle, characterized by a pair of beams having their inner ends pivotally attached to the frame at a pair of respective first points for pivotal movement about the first transverse, horizontal axis thereat; a lifting fork pivotally attached to the main beams at their respective outer ends at a pair of respective second points and having lift prongs adapted to load the junk cars onto a transport vehicle; elevating rams connected with the main beams and the frame for elevating the junk cars; and load fork tilting rams attached to the main frame at a pair of respective third points for pivotal movement about a second transverse, horizontal axis thereat. The lift fork tilting rams are attached to the lift fork at a pair of respective fourth points.

Abstract: A means for pivotally mounting the bellcrank of a bucket linkage between the boom arms of a loader, including pivot castings secured to each of the boom arms, a shaft extending through said pivot castings and the bellcrank, a plate secured to one end of the shaft and bolted to the adjacent pivot casting to prevent rotation of the shaft relative to the boom arms, and a second plate bolted to the other end of said shaft to limit inward axial movement of the shaft relative to the adjacent pivot casting.
