摘要： A materials handling device suitable for mounting on a structure, such as a pickup truck, so that heavy materials, such as cylindrical bales of hay, can be selectively loaded and unloaded onto the pickup truck for transportation from one location to another. The materials handling device comprises a housing assembly pivotally connected to the support structure so that the housing assembly is substantially vertically disposed adjacent an edge of the support structure; a frame slideably positioned within the housing assembly; a material engaging assembly mounted on the lower end portion of the frame so as to extend in a direction away from the support structure; and a frame and housing actuator assembly disposed between and interconnecting the support structure and the upper end portion of the frame. The actuator assembly, which is pivotally connected to the frame and the support structure, selectively moves the frame between a vertically lowered position and the vertically raised position. When the frame is in the vertically raised position the actuator assembly selectively moves the housing assembly between the vertically disposed position and a horizontally disposed position wherein the housing assembly, and thus the frame, are disposed on the support structure. The materials handling device further includes a cradle assembly pivotally connected to the support structure so as to be substantially aligned with the housing and the frame, and a cradle actuator assembly disposed between and pivotally connected to the support structure and the cradle assembly.
