A reach back carrier includes a self-propelled tractor and a wheeled trailer having a generally U-shaped frame with rearwardly projecting side members and a forwardly projecting integral gooseneck pivotally connected to the tractor to permit turning thereof at substantially right angles, a cradle is pivotally mounted adjacent the rear ends of the side members and adapted to engage trunnions on the pot. A rear cross frame is secured between the side members and has rigidly attached rearwardly projecting mounting members thereon with a plurality of trailer wheels journalled on transverse axes adjacent the ends of the side members and mounting members for supporting the trailer, at least one of the wheels on each side of the trailer center line having an axis set forward of the axes of the other wheels, a rear hydraulic actuator secured to at least one of the side members and mounting members behind each of the one wheels, the hydraulic actuator being located substantially within the overall length and width of the trailer defined by the outer perimeter of the wheels and has an outrigger foot for engaging the ground when the pot is lifted and dumped by the cradle, and a primary hydraulic actuator for swinging the cradle about the pivotal mounting for lifting the pot through the trunnions from a position behind the trailer wheels and swinging the pot into a transport position on the trailer ahead of the wheels. |
