  • Patent number: 11752914
    Abstract: A trailer system may have a first cargo area having a movable deck. The movable deck may be moved by an actuator. The movable deck may include a plurality of first rollers for engaging and translating cargo. And a movable tailgate may close the first cargo area when it is in a first position. The movable tailgate may have a plurality of second rollers for engaging and translating cargo when the movable tailgate is in a second position. The trailer system may have a plurality of movable decks, where each movable deck is coupled and moved by an actuator. Each actuator may comprise at least one of a hydraulic, pneumatic, and/or electromechanical system. The trailer system may further have a set of lower movable decks and a set of upper movable decks. The set of upper movable decks may be coupled to the lower movable decks by actuators.

  • Patent number: 9909550
    Abstract: Improved remote start/stop systems and methods for use with a truck and/or vehicle transport trailer. Embodiments include a transport trailer and truck, the trailer comprising a platform that moves in response to a hydraulic system coupled to the platform. The hydraulic system is powered by the truck engine. A pressure transducer in communication with the hydraulic system is configured to measure a change in hydraulic pressure. A start/stop controller is in communication with the pressure transducer. The start/stop controller is configured to receive the measurements from the pressure transducer, determine to turn off the truck engine in response to the measurements, and provide an message via an indicator in communication with the start/stop controller, the indicator located proximate to a hydraulic control for the first hydraulic system. Some embodiments include a button that may override turning off the truck engine, or cause the truck engine to restart.

  • Patent number: 9610884
    Abstract: A ratcheting tie down apparatus and system. Embodiments include a ratchet assembly affixed to a tie down shaft having a longitudinal axis, the ratchet assembly including a ratchet gear, a ratchet head, a ring pawl between the ratchet gear and the ratchet head, and a compression spring between the ring pawl and the ratchet head. A plurality of ramped protrusions of the ring pawl engage a plurality of ramped indentations in a back surface of the ratchet gear, such that when the ratchet head is rotated in a first direction, the ring pawl engages the ratchet gear so that the ratchet head and ratchet gear rotate as a single unit, and when the ratchet head is rotated in a second direction the ring pawl disengages from the ratchet gear such that the ratchet head and ratchet gear rotate independently.

  • Patent number: 8382406
    Abstract: A parallel shaft strap tie down apparatus and system. Exemplary embodiments include a parallel shaft strap tie down apparatus and system for vehicle transports. Exemplary embodiments include a central shaft having a ratchet wheel and a pawl configured to wrap a strap around the central shaft. A parallel shaft is positioned parallel to the central shaft. The strap can be inserted between a variable gap between the central shaft and the parallel shaft. When the central shaft is rotated the strap is wound around the central shaft and the parallel shaft, both of which cooperate to create a self-tightening response of the strap on the central and parallel shafts.
