Abstract:
An over the road trailer having adjustable sections to provide different trailer configurations. A flat center bed section has a sliding connection at the front with vertical legs of a gooseneck section and a sliding connection at the back with vertical legs of an L-shaped rear section. Hydraulic jacks move the center section up and down to allow the trailer to assume a double drop deck configuration, a step deck configuration, or a straight deck configuration. Separate power operated and manually operated latching systems secure the trailer in each different configuration.
Abstract:
A pair of main beams, a plurality of diagonal cross braces and transverse beams having a beam height of about 75% of prior art main beam heights provide a relatively flexible chassis. A clamp assembly central of the chassis clamps a cubicle cargo container central region to the chassis to rigidify the chassis. The cargo container is connected to the chassis front and rear by conventional bolster pin and twist lock assemblies. An upper container casting has an opening for receiving an interbox twist lock connector aligned on an axis closely spaced to the side panels of upper and lower containers on a rail car to minimize bending loads on lower container intermediate support posts. Lower castings at the base of each of the intermediate posts mate with a lower container upper castings in a stacked arrangement on a rail car. The chassis has a bogie assembly receiving channel for slidably receiving a bogie locked to the chassis by a conventional retractable pin mechanism. The container tunnel has a trapezoidal transverse section which mates with a chassis goose neck which is 10% narrower than and about 50% the vertical height of prior goose necks.
Abstract:
An automatic, pneumatically operated flatrack lockdown device is provided for a palletized load system trailer. The lockdown device includes a manual release system which can override the pneumatic system when, for example, the pneumatic system fails. The release system includes a main handle, which when pivoted unlocks the flatrack. In one embodiment, the release system further includes a locking assembly which prevents the main handle from unlocking the flatrack , and a pair of release handles, each of which release the locking assembly to allow for operation of the main handle.
Abstract:
A new supporting structure for a mobile home comprising pre-stressed concrete and a method for making same. The supporting structure comprises a rectangular floor, supported by beams on the lower surface of the floor. A pair of large longitudinal beams are formed on the lower surface of the floor adjacent the longitudinal edge of the floor. A plurality of smaller transverse beams are formed on the lower surface of the floor connecting the longitudinal beams. Both the longitudinal and transverse beams are pre-stressed. Means for attaching wheels and a towing hitch are provided. The supporting structure is cast in a single piece in a bed provided with channels for the longitudinal and transverse beams. The beams are pre-stressed in a conventional manner either by pre-tensioning or post-tensioning tendons. After the concrete has set and the tendons anchored, the supporting structure is lifted out, and wheels and a towing hitch attached. Walls and the upper structure are later attached by means of studs cast in the concrete floor.
Abstract:
An improved trailer apparatus for transporting house structures or the like having a support beam assembly connected to a trailer fifth wheel assembly for raising, lowering, and supporting the house structure. The trailer apparatus includes a rearward beam elevation assembly raising and lowering the rearward end portion of the support beam assembly and a road dolly assembly removably connectable to the support beam assembly rollingly supporting the rearward end portion of the support beam assembly when connected thereto, the rearward end portion of the support beam assembly being supported via a plant dolly assembly in one assembled position of the trailer apparatus.
