  • Patent number: 5667231
    Abstract: A trailer comprising a wheeled frame including a main deck and an upper deck positioned thereon. The rearward end of the upper deck is pivotally interconnected to the forward end of the main deck by multiple arms which maintain the upper deck in a substantially horizontal position while the main deck is being pivoted with respect to the upper deck. A suspension system is slidably mounted on the wheeled frame and is slidably movable from a transport position to a tilt position forwardly therefrom to enable the main deck to be pivoted so that the rearward end of the main deck may be moved into ground engagement to enable equipment or the like to be mounted on the trailer.

  • Patent number: 5490754
    Abstract: A trailer comprising a lower main deck and an upper deck positioned forwardly and upwardly of the main deck and including an upper deck ramp positioned at the forward end of the main deck which may be pivotally moved upwardly so that freight or equipment may be moved upwardly thereon from the main deck to the upper deck. Pivotally connected upper and lower scissor arms are provided at the opposite sides of the forward end of the upper deck ramp. A hydraulic cylinder is connected to each of the lower scissor arms adjacent the upper end thereof. The upper end of each of the upper scissor arms is connected to the forward end of the upper deck ramp with the lower end of the lower scissor arms being pivotally connected to the trailer frame. Extension of the hydraulic cylinders causes the scissor arms to spread apart to raise the upper deck ramp from a stored position to an inclined position.

  • Patent number: 4701098
    Abstract: A cable reel handling and transporting trailer including a wheeled frame having a forwardly extending hitch provided on the forward end thereof. The wheeled frame includes a pair of laterally spaced-apart and longitudinally extending side frames having a wheel rotatably mounted thereon. A hydraulically operated leveling arm is pivotally mounted on each of the side frames and is adapted to engage a spindle reel assembly extended through a cable reel to roll the spindle reel assembly forwardly on the leveling arms. When the spindle reel assembly has reached the forward end of the leveling arms, a pair of hydraulic cylinders are actuated which engage the opposite ends of the spindle reel assembly so that the spindle reel assembly and the cable reel are moved upwardly on a forwardly extending guide rail into a lock/transport/rotating position. A hydraulic motor is operatively connected to one end of the spindle reel assembly for laying and retrieving the cable on the cable reel.
