Abstract: Aspects of the disclosure relate to a trailer having a frame suitable for transporting an item, such as an oil drilling pipe. The trailer includes a plurality of stabilizers for supporting the frame over a surface, at least one axle attached to a plurality of wheels. The trailer further includes an axle pin group includes first and second axle pins interconnected to respective hydraulic cylinders. The trailer further includes leaf springs connected to respective sides of the frame and mounted to the axle. Retraction of the axle pins away from the leaf springs enables movement of the frame with respect to the axle due to the weight of the frame, if the stabilizers are retracted. In this configuration, the frame can be raised and lowered with respect to the surface. Methods of use are also disclosed.

Abstract: A pole carrying device and method of using the pole carrying device is disclosed, wherein the pole carrying device is designed to carry and maneuver poles or pipes in a safe and easily controlled manner. In one example, the pole carrying device comprises a main beam that is supported by a wheel assembly, wherein the wheel assembly comprises two wheels. Further, two cradles are mounted atop the main beam (e.g., one at each end) for holding the poles or pipes. The method of using the pole carrying device includes, but is not limited to, the steps of providing the pole carrying device in an at rest position, placing the poles or pipes atop the pole carrying device, and rolling the pole carrying device along the ground and thereby transporting the poles or pipes.

Abstract: This invention relates to a trailer comprising a body, a wheel assembly on each side of and floating relative to the trailer body, a linear actuator driving means adapted to selectively raise and lower body relative to its wheel assemblies while keeping the body substantially parallel to the ground throughout its range of movement and providing a mechanical advantage to the actuator.

Abstract: An adjustable run height lift axle suspension system includes an axle assembly, an air spring and a lift actuator. A device may be releasably attached to the axle assembly and connected to each of the air spring and the lift actuator, the device spacing the air spring away from the axle assembly. A selected one of multiple devices may be used, the suspension system having one run height when one device is releasably attached to the axle assembly and connected to each of the air spring and the lift actuator, and a different run height when another device is used. The air spring may have approximately the same operational height when the suspension system is at the different run heights.

Abstract: A retractable wheel assembly is provided for coupling to a mounting on an object. The retractable wheel assembly is moveable between one or more extended positions and a retracted position. The retractable wheel assembly is configured to expose a wheel in the extended position(s) and to stow said wheel in the retracted position. The retractable wheel assembly comprises a first wheel strut rotatably mounted at or proximate a first end thereof, a first link arm handle rotatably coupled at or proximate a second end of the first wheel strut, and a first over-centre locking arm rotatably coupled at or proximate a first end to the first link arm handle and rotatably mounted at a second end thereof.

Abstract: A trailer leveling system for adjusting a height of a frame of a trailer above a ground surface is disclosed. The trailer leveling system comprises at least one trailer leveling apparatus configured to adjust a distance between an axle of the trailer and the frame of the trailer. The at least one trailer leveling apparatus acts on a suspension of the trailer. The at least one trailer leveling apparatus moving the suspension between a traveling position and a leveling position, with the traveling position being characterized by the suspension being capable of supporting the frame during movement of the trailer along a road and the leveling position being characterized by a portion of the suspension being moved away from the frame with respect to the travel position.

Abstract: A low profile chassis and suspension system for a road vehicle. The chassis supports a payload section or cargo compartment, such as for a delivery truck, ambulance, or shuttle bus. The chassis includes a largely planar frame having a top surface which is located beneath the rotational axes of the rear wheels. The wheel suspension system is particularly compact and close to the road surface. A trailing arm-type wheel support supports a stub axle in a cantilevered fashion. A spring urges the wheel support apart from the frame. A planar portion of the wheel support, the wheel support pivot joints, and the spring are located beneath the rotational axis of the wheel. In another embodiment, the frame includes a recessed pocket which facilitates use of ramp for wheel chair access.

Abstract: An elevating trailer for moving between a low, cargo-loading position and an elevated, cargo-transporting position. The frame of the trailer has opposing sides, each side carrying a pair of tandem wheels. An inflatable air bag is mounted on a supporting and pivotal frame above the trailer side. When the bags are inflated the arms of the supporting frames are spread apart, lifting the frame. When the bags are deflated, the arms pivot toward each other, lowering the frame and facilitating loading of cargo into a container mounted on the trailer frame.

Abstract: A pivoting bed trailer to be towed behind a motor vehicle for transporting a wheeled vehicle includes a main frame having a trailer hitch at a front end for coupling with the motor vehicle and a rearward end that engages the ground in an inclined loading condition and supported horizontally above the ground in a transporting condition. The main frame includes longitudinally extending guide rails for laterally aligning the vehicle. A pivot frame frontally and laterally bounds the main frame and the guide rails and is connected to said main frame at a transverse pivotal connection. The pivot frame includes pair of laterally spaced wheel assemblies carried by leaf spring below the pivot frame forward of the pivotal connection whereby rotation of the pivot frame about the wheels raises and lowers the transverse pivotal connection and moves the main frame between the loading condition and the transporting condition.

Abstract: A trailer for use in transporting a load from one area to another area has a frame and a bed operatively mounted to the frame which is capable of being moved from a first or lowered position to a second or elevated position in a substantially vertical manner or nontilting manner. At least one lifting mechanism is operatively connected to the bed, which applies the greatest force for lifting the bed from the lowered position to the elevated position at the beginning of the lift, rather than at an end or midpoint of the lift. At least one over-center latching mechanism secures the bed to the frame when the bed is in the elevated position.
