发明名称 Apparatus for lifting and transporting large bales of material
摘要 Apparatus is provided for handling one or more large bales of material. A mobile chassis forms a load-carrying chamber open at the rear end so that the chassis can be backed over one or more bales. A tongue is attached to the forward end of the chassis. The tongue is preferably attached to the chassis for between a position in which the motive vehicle and the chassis are in longitudinal alignment and a second position in which the motive vehicle is parallel with and laterally offset from the chassis, leaving the front of the chassis open to be pulled forward over one or more bales. A pair of load-lifting and supporting members are pivotally attached to the respective sides of the load-carrying chamber. Track members extend transversely across the top of the load-carrying chamber, with a pair of carriages adapted to move outwardly along the track members. Longitudinally expandable force members are connected between the carriages and the load-lifting structures. With the force members fully extended, the carriages are positioned adjacent the respective sides of the load-carrying chamber, and the force members extending downwardly to the load-lifting members. When the force members are shortened, the load-lifting members pivot outwardly and upwardly into their elevated, load supporting position, and the carriages move towards the center of the load-carrying chamber to maintain the force members in a substantially vertical position, thereby exerting maximum force on the load-lifting members.
