A portable dock trailer is provided herein. In various embodiments, the portable dock trailer includes a frame, a ramp, a loading deck, and a mechanism for raising and lowering the ramp. The portable dock trailer permits the loading and unloading of cargo when a traditional loading dock is not available. Embodiments of the portable dock trailer are configured to assume a towing position to be used during transport and a loading position to be used at a loading site.

The disclosed devices, systems and methods relate to a split-tilt deck trailer. A tilting deck and stationary deck are disposed in parallel on the trailer to provide a tilting deck for the loading of various equipment and providing an elongate stationary platform simultaneously.

A trailer with at least one tilting axle unit, comprising a telescopic support or slide (3), a hinge (221) and a fifth-wheel coupling (4), designed to longitudinally move at least one posterior axle unit and to lift and rotate it so that a vehicle can be loaded on a loading deck (13) of said trailer.

The present invention may disclose a turbine fracturing equipment, including a transporter, a turbine engine, a reduction gearbox, a transmission mechanism and a plunger pump, wherein an output end of the turbine engine may be connected to one end of the reduction gearbox, the other end of the reduction gearbox may be connected to the plunger pump through a transmission mechanism; the transporter may be used to support the turbine engine, the reduction gearbox, the transmission mechanism and the plunger pump; the transporter may include a chassis provided with a transport section, a bearing section and a lapping section which may be connected in sequence; while the turbine fracturing equipment may be in a working state, the bearing section can contact with the ground, while the turbine fracturing equipment may be in a transport state, the bearing section may not contact with the ground.

A portable towing system for a motorcycle or similar vehicle, such as a trike, the frame of which can be lowered to ground level to facilitate loading of the motorcycle or similar vehicle by pushing or riding the vehicle onto the frame without risk of the vehicle falling off the sides of a steeply inclined ramp. The towing system may be assembled, raised, lowered, and disassembled by a single person, if desired. The raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies.

A bogie for a lowboy trailer includes a pair of longitudinally extending main beams, each having a lower front end configured to be coupled to a lower deck, a higher rear portion configured to carry a suspension system, and a sloped intermediate portion connecting the front end to the rear portion. The bogie also includes multiple transversely extending and longitudinally spaced cross-members connected between the main beams. Each of the cross-members is trough-shaped and has a pair of transversely spaced side sections and a midsection between the side sections, the side sections sloping downwardly toward the midsection such that a top surface of the midsection is lower than respective top surfaces of the main beams. Each side section of at least one cross-member intersects with a respective one of the main beams, such that at least a portion of each side section is located directly below the respective main beam.

A system for monitoring the use of one or more lift devices used for raising or lowering the landing gear of a semi-trailer. A data management module within the system includes a suite of features which are used to take received lift device data and convert it into an easily understood graphical representation. Each lift device is configured to transmit data related to its operation to the data management module of the system which then displays the lift device data as a graphical representation and/or data set according to the type of user using the system. The lift device data which is displayed to the user can include an amount of torque applied to the lift device, the number of times the lift device has been activated, or any other data point which gives the user an overall snapshot of the performance of the lift device(s) under their control.

A drop deck trailer is provided with a deck that has the ability to raise and lower to conveniently load and unload goods and materials on the deck. A pneumatic system can raise and lower the deck and also serve as a suspension system for the trailer to dampen the relative movement between a frame and the deck. In addition, some embodiments of the trailer have a deck with a movable carriage that can move along the deck to automatically load a vehicle such as a golf cart. The carriage has rollers that secure the front wheels of a vehicle, and the carriage moves along the decks to pull the vehicle onto the deck. Moreover, various embodiments of a trailer frame can selectively connect to different decks to allow each deck to be specialized for particular goods and materials.

A trailer having a hitch assembly, a deck assembly, an axle assembly and a structural joint positioned between the deck assembly and the axle assembly is provided. The deck assembly having a first support beams and a second support beams supporting decking. The first support beam and the second support beam can have a positive camber. At least one shim plate can be rotatable between a joint position, wherein the at least one shim plate is positioned in the structural joint, and a storage position, wherein the at least one shim plate is rotated out of the structural joint to adjust the amount of camber in the support beams.

A portable towing system for a motorcycle or similar vehicle, such as a trike, the frame of which can be lowered to ground level to facilitate loading of the motorcycle or similar vehicle by pushing or riding the vehicle onto the frame without risk of the vehicle falling off the sides of a steeply inclined ramp. The towing system may be assembled, raised, lowered, and disassembled by a single person, if desired. The raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies.
