A lifting device (10) is provided for lifting bales (14) of material. In broad terms, the lifting device (10) comprises a lifting arm assembly (12), and a winch assembly (16). The lifting arm assembly (12) includes a pair of lifting arms (22,24) pivotally coupled with an axle (26), and a closing arm (28). The lifting arms (22,24) are shiftable between spread and drawn positions, and between lowered and raised positions. A linkage assembly (86) intercouples the lifting arms (22,24), and is adapted for shifting the lifting arms (22,24) between the spread and drawn positions. The closing arm (28) is pivotally attached to the axle (26), and is adapted to engage the linkage assembly (86) for shifting the lifting arms (22,24). The closing arm (28) is shiftable between a bale-disengaging position where the lifting arms (22,24) are in the spread position, and a bale-engaging position where the lifting arms (22,24) are in the drawn position. The closing arm (28) is also shiftable toward a bale-transporting position for rotating the axle (26) to shift the lifting arms (22,24) toward the raised position. The winch assembly (16) is adapted for selectively shifting the closing arm (28) between the bale-disengaging and bale-transporting positions.
