Abstract
A trailer moveable by a cab includes: a first section including a cavity; and a second section including a beam at least partially positioned within the cavity and a height-variable member attached to the beam, where the second section is longitudinally movable relative to the first section, such that a length of the trailer is variable, where the second section includes a cart pivotably attached to the beam at a fulcrum, where the cart includes at least one wheel configured to roll along a floor of the cavity, where the cart is pivotable about the fulcrum to co-act with the height-variable member, where the second section is configured to move longitudinally relative to the first section by the cart rolling along the floor of the cavity.

A trailer moveable by a cab, comprising:
- a first section comprising a cavity;
- and
- a second section comprising a beam at least partially positioned within the cavity and a height-variable member attached to the beam, wherein the second section is longitudinally movable relative to the first section, such that a length of the trailer is variable,
- wherein the second section comprises a cart pivotably attached to the beam at a fulcrum, wherein the cart comprises at least one wheel configured to roll along a floor of the cavity, wherein the cart is pivotable about the fulcrum to co-act with the height-variable member,
- wherein the second section is configured to move longitudinally relative to the first section by the cart rolling along the floor of the cavity.
A method for adjusting a length of a trailer moveable by a cab, comprising:
- providing a first section of the trailer, the first section comprising a cavity;
- inserting a second section of the trailer into the cavity and moving the second section longitudinally relative to the first section to a first trailer length;
- and
- fixing the trailer at the first trailer length by restricting longitudinal movement of the first section relative to the second section,
- wherein the second section comprises a cart pivotably attached to the beam at a fulcrum, wherein the cart comprises at least one wheel configured to roll along a floor of the cavity, wherein the cart is pivotable about the fulcrum to co-act with the height-variable member, wherein the second section is configured to move longitudinally relative to the first section by the cart rolling along the floor of the cavity.
