20080231016 | TRAILER COMBINED WITH A MOVABLE WHEEL ASSEMBLY - A trailer combined with a movable wheel assembly. The trailer comprises a front portion and a load carrying bed portion. The front portion is combined with the load carrying bed portion at a pivot point so that the front portion and load carrying bed portion can pivot relative to each other. A rack and pinion means allows selective movement of the wheel assembly relative to the trailer. The rack is combined with the load carrying bed portion of the trailer, and the pinion is combined with the movable wheel assembly. A power assist means, such as a hydraulic motor, is combined with the movable wheel assembly and is adapted to rotate the pinion. Activation of the power assist means rotates the pinion and moves the wheel assembly in a first direction along the rack towards the front of the load carrying bed or in a second direction along the rack towards the rear of the load carrying bed. As the wheel assembly is moved toward the front of the load carrying bed, the rear end of the load carrying bed can be lowered to the ground to act as a ramp to allow objects to be loaded or unloaded from the trailer. | 09-25-2008 |

20110049837 | SYSTEM AND METHOD FOR DETERMINING WHETHER THE WEIGHT OF A VEHICLE EQUIPPED WITH AN AIR-RIDE SUSPENSION EXCEEDS PREDETERMINED ROADWAY WEIGHT LIMITATIONS - A system and method for determining whether a vehicle and its axles exceed predetermined roadway weight limitations. Air fittings are installed in the air-ride systems of the vehicle. Air pressure readings taken using a hand held gauge are compared to maximum pressure values marked on the vehicle. If the air pressure exceeds the values, weight may be redistributed, if possible, until measured pressure is equal to or less than the maximum pressure values. The method allows an operator to quickly confirm that the total weight and axle weight does not exceed legal limits without the use of truck scales. | 03-03-2011 |

A tilt selector receives a bolt through a hole and is connected to one of the shank portion and the ball mount head with two pegs extending into two of at least three connection points on the ball mount head. An operator selects which two out of the connection points to use, which determines and sets the location of the tilt selector bolt hole relative to the ball mount head, which in turn determines and sets the angular position of the ball mount head relative to the shank portion when the bolt is tightened. | 04-16-2015 |
280407100 | Semitrailer type | 4 |
20090051141 | Portable rock crawl course - A portable rock crawl course, including one or more trailers, each having a trailer bed, side walls, top panels, front end wall, and tailgate, each having synthetic rocks formed thereon and arranged such that when the walls, top panels and tailgates are pivoted to form a closed trailer, the synthetic rocks are nested inside and such that the side and end walls, top panels and tailgate are pivotable to form a crawl course over which vehicles travel, and wherein multiple trailers can be arranged to form multiple trailer crawl courses. | 02-26-2009 |
20090108562 | METHOD AND APPARATUS FOR TRANSITIONING A HEAVY EQUIPMENT HAULING REAR LOADING TRAILER BETWEEN TRANSPORT AND LOADING POSITIONS - A lowboy trailer is described having a pair of rear wheel assemblies mounted to a chassis of the trailer for movement between transport and loading positions such that the wheel assemblies are aligned across a back of the body when they are in the transport position and raised and positioned outwardly when the chassis is in the loading position. A linkage mechanism moves each of the wheel assemblies between the transport and loading positions. Each linkage mechanism automatically fastens the wheel assembly to the chassis of the trailer when the assembly is moved to its transport position. In operation, each of the wheel assemblies is moved from its transport position to the loading position by first moving to an intermediate raised position. By moving the wheel assemblies to the raised position they are automatically unfastened from the chassis and freed to move outwardly about a vertical pivot axis. Also, by raising the wheel assemblies, the back end of the chassis is lowered to the ground, which is the loading position for the trailer. To return the trailer to its transport position, the rear wheel assemblies are moved inwardly about the vertical axes so as to bring the assemblies back to their intermediate raised position. Then the wheel assemblies are lowered so that each of them automatically fastens to the body, thereby preventing lateral movement of the assemblies as the trailer moves into its transport position. | 04-30-2009 |
20090315297 | TRAILER - Improved trailers (e.g., semi-trailers) are disclosed. The trailers may include a floor having a top surface and a bottom surface, where the top surface is adapted to transport a payload, and an elongated shell connected to the bottom surface of the floor, where the elongated shell defines a portion of a substantially closed torsion-resistant chamber of the trailer. The trailers may have a torsion resistance that is substantially higher than conventional trailers of similar size and/or load capacity. The trailers may weigh substantially less than conventional trailers of similar size and/or load capacity. The trailers may realize a bending resistance that is at least equivalent to the bending resistance of conventional trailers of similar size and/or load capacity. | 12-24-2009 |
20160114716 | INTERMODAL CHASSIS - 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. | 04-28-2016 |
