Present embodiments provide an automated system for laying pipe which includes various clearing functions in order to clear impingements and jams of pipe being fed to a conveyor or other structure while dispensing the pipe from the trailer. Some embodiments include uprights which are adjustable to increase the carrying capacity of piping. Other embodiments provide adjustable members which raise and lower to aid in clearing the pipe. Other embodiments provide a gate or arm which may be actuated to push or hold pipes back allowing one pipe to feed at a time. Still further, a transition cradle may be utilized to hold pipes back and actuate a single pipe. These features allow for clearing of various types of jams in the feed process so that a single pipe may be cleanly actuated to a conveyor for feeding from the vehicle.

A trailer assembly suitable for carrying a container of proppant has a frame with a first side rail and a second side rail extending in generally parallel relation to each other and a plurality of wheels rotatably mounted below the frame. The frame has a plurality of cross members extending between the side rails. First and second outriggers extend across the side rails so as to each have one end extending outwardly of one of the side rails and an opposite end extending outwardly of the other side rail. The first and second outriggers are suitable for receiving the container of proppant thereon. The frame has a first section positioned above the wheels and a second section positioned at a level lower than a level of the first section. The proppant container is placed on the first section.

An intermodal chassis for highway transportation of shipping containers, the chassis having a forward axle and a rear axle, and incorporating an air bag suspension that automatically deflate the air bags when the brakes are locked, preventing damage when loading a container onto the chassis. Large 53 foot long box/high cube type shipping containers may be loaded along their entire length with the chassis having a rear axle positioned under the chassis frame so that the kingpin-to-rear-axle length is no more than 40 feet, and a forward axle positioned under the frame between the gooseneck and the rear axle so that a forward-to-rear-axle length is at least 12 feet. Other features include self-scaling and load-leveling, and other weight savings include use of smaller sized aluminum wheels.

Disclosed is a trailer including a bed portion. The bed portion includes a deck, a front extension, and a rear extension. The deck has a first end and a second end. The front extension is slideably engaged with the first end of the deck, and the rear extension is slideably engaged with the second end of the deck. The trailer is a double stretch trailer that is extendable from both ends of the deck. A towing system including a cab and the trailer is also disclosed.

A trailer is provided for having a self-propelled swather mounted thereon. The trailer includes first and second caster wheel supports and first and second drive wheel supports. The caster wheel supports are selectively movable being stowed and support positions. The drive wheel supports are selectively movable between horizontally disposed and vertically disposed positions. Each of the caster wheel supports includes a caster wheel turning assembly to partially pivot the associated caster wheel as the swather is backed onto the trailer. The trailer also includes extenders for attachment to first and second ramps. The extenders may be stowed on the bumper.

A trailer system with a trailer and a booster is provided. The trailer can have a hitch assembly provided at a front end of the trailer, a load bed provided behind the hitch assembly, and an axle assembly. The booster can have a connection assembly pivotally connecting the booster to a rear end of the trailer and an axle assembly. The connection assembly can include a booster hydraulic cylinder to dampen the pivoting of the booster; and an axle assembly comprising: a booster suspension frame; at least one axle; ground wheels provided on each axle; a booster suspension having at least one booster suspension air spring controlling the height of the booster suspension frame relative to the ground wheels; and a pressure regulator limiting the maximum pressure of a fluid supplied to the at least one booster suspension air spring.

A novel method of repairing and modifying a heavy-duty industrial rack includes: a) providing an enclosed trailer having: 1) a forklift compartment; 2) a ramp for the loading and unloading a forklift and its payload to and from the trailer; 3) a forklift for moving a rack to and from the trailer; 4) a rack repair compartment; 5) rack repair raw materials; 6) at least one rack component bonding apparatus for bonding components of the rack; 7) at least one rack component bending apparatus; 8) at least one rack machining apparatus; and 9) a hitch for coupling the trailer to a truck for moving the trailer to a new location when desired; and b) moving the trailer to an onsite location having a rack targeted for repair or modification. The method also at least includes: c) unloading the forklift from the trailer via the ramp; d) driving to the forklift to the targeted rack; e) lifting the targeted rack and transporting it to the trailer; f) loading the targeted rack onto the trailer via the ramp; g) locating the targeted industrial rack in the rack repair compartment; h) performing repairs or modifications on the rack; i) after pairs or modifications, lifting and removing the rack from the trailer via the forklift and the ramp; j) driving the repaired or modified rack to an onsite location; and k) unloading the repaired or modified rack from the forklift. A novel trailer apparatus is separately disclosed.

An intermodal chassis for highway transportation of 53 foot shipping containers having a rear axle positioned under the chassis frame so that the kingpin-to-rear-axle length is no more than 40 feet, and a forward axle positioned under the frame between the gooseneck and the rear axle so that a forward-to-rear-axle length is at least 12 feet. The chassis includes air bag suspension that automatically deflate the air bags when the brakes are locked, preventing damage when loading a container onto the chassis. Other features include self-scaling and load-leveling, and other weight savings include use of smaller sized aluminum wheels.

A portable weighing hopper assembly for use in precisely loading bulk material or commodities in a shipping container or vessel which includes a wheeled frame having first and second metered hoppers mounted thereon. A primary hopper is mounted on the wheeled frame for supplying material to either the first and second metered hoppers. A transfer valve is positioned between the discharge end of the primary hopper and the first and second metered hoppers for directing material from the primary hopper to either the first and second metered hoppers. A slide gate is positioned between the lower outlet end of the primary hopper and the transfer valve. Load cells are associated with the first and second metered hoppers which supplies the weight information to a CPU. The CPU controls the flow of material from the metered hoppers to a conveyor which discharges the material into a shipping container or the like.

A trailer neck reinforcement structure includes a first beam reinforcement structure that includes: (i) a first beam inner insert connected to an inner side of the first beam; and, (ii) and a first beam outer insert connected to an outer side of the first beam. A second beam reinforcement structure includes: (i) a second beam inner insert connected to an inner side of the second beam; and, (ii) and a second beam outer insert connected to an outer side of the second beam. Internal cross members extend between the first beam inner insert and the second beam inner insert. A first group of external cross members are located between the first beam outer insert and the left side rail, and a second group of external cross members are located between the second beam outer insert and the right side rail. Each external cross member comprises an inner segment connected to an outer segment.
