Abstract: A trailer unloading system anchors one or more trailers to a deck, with, or without tractor attached. The sides of the trailers are free to pivot from a top, longitudinal, pivot axis once unlatched from the edge of the trailer floor. The deck tilts the trailers sideways, the doors swing free, and the load discharges. The deck returns to level, the sides latch to support the floor and the trailers are ready to be reloaded.

Abstract: A connector system for coupling a suspension frame device to the rear part of a transport trailer for use in distributing the weight of the load of the trailer to extra wheels and/or providing an effective attachment arrangement for connecting a second trailer behind the first trailer in tandem fashion. The connector system includes a part formed at the front of the suspension frame device which includes a rigid frame portion carried by an additional set or sets of wheels, and the connector system further includes a second part formed integrally at the rear of the frame of the first trailer, the two parts having mating guiding portions for properly aligning the suspension frame device with the trailer as the parts come to an initial hitching position.

Abstract: A versatile and easily serviceable material spreading apparatus of the type for movement over a ground surface while broadcasting a material along a path on the ground surface. The apparatus includes a belt cartridge which can be slid into or pulled out of a chassis compartment having ledges for supporting the cartridge. The belt cartridge provides an upper flight on which material is carried from a hopper supported on the chassis to a broadcasting unit carried at one end of the chassis. A plurality of broadcasting units each of which has an attachment component, which in combination with a mating attachment component carried by the chassis, permits quick fastening and removal of each unit relative to the chassis. One of the broadcasting units mounts an elongated rotatable member below a drop-off end of the upper flight of the belt cartridge, and the rotatable member is driven in a direction so that the upper rotating periphery of the rotating member propels the material upward and away from the chassis.
