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.

Abstract: Exemplary embodiments of a system and method for cargo height observation are disclosed. Certain embodiments are configured such that a user, such as a tractor operator, may verify that an overall height of the car hauler, as may be dictated by the height positions of one or more vehicles positioned on ramps associated with an upper deck of the car hauler, is below a predetermined allowable height for the car hauler when being transported over public or private roadways.

Abstract: An automatically extending and retracting step system according to the solution may reside in a retracted state when the deck of a car-carrying vehicle is substantially horizontal to the ground, i.e. when the deck is in a payload state. Advantageously, when the deck is tilted and extended to a ramp state for receiving cargo, the step system according to the solution extends laterally outward from beneath the deck, thereby providing a convenient and visible step for a user to use in getting down from the deck. When the deck is returned from the ramp state to its payload state, the step automatically retracts to a travel state beneath the deck.
