Abstract: A modular conveyor apparatus includes a plurality of substantially identical conveyor segments. Each conveyor segment has a pair of laterally spaced protrusions or hooks extending from one end thereof. Each conveyor segment has a plurality of spaced openings or slots along at least one of its side walls, so that two like conveyor segments can be connected together perpendicularly with the hooks of a first segment received in the side wall slots of a second segment. Thus the perpendicular connection between two conveyor segments may be made at any selected one of a plurality of locations along the length of each conveyor. Provision may also be made for end to end connection of the conveyor segments.

Abstract: Each of a pair of skid plate assemblies attaches by a mounting plate to the axle and leaf springs of a trailer using inverted U-bolt. The steel skid plate mounts to the mounting plate by a vertical steel tube and two welded angled brace tubes. The front end of the bottom skid plate hooks around and attaches to a crossbar on a bracket hanging down from a forward end of the trailer spring. The back end of the bottom skid plate is formed with a dove tail tip that touches the pavement to create sparks when the trailer tire is disabled to warn other motorists.
