Abstract
A tail trailer includes a main deck mounted on a main frame, a main tail pivotally connected to a rearward end of the main deck and a flip tail pivotally secured to a rearward end of the main tail. The flip tail is movable between a folded position beneath the main tail and an unfolded position extending outwardly from the rearward end of the main tail. A lifting and holding, assembly is provided between the main frame and the main tail for pivotally moving and maintaining a desired position of the main tail and the flip tail relative to the main deck. A combined locking and supporting arrangement beneath the main tail provides ground engaging support for the main tail, and also provides locking engagement for holding the flip tail in the folded position.

A tail trailer supported for movement on a ground surface, the trailer comprising;
- a main deck mounted on a wheeled main frame and provided with a forward end and a rearward end:
- a tail assembly having a rearward end configured to engage the ground surface and a forward end pivotally coupled to the rearward end of the main deck;
- and
- a lifting, and holding assembly for pivotally moving and maintaining the tail assembly in a desired position relative to the main deck, wherein the lifting and holding, assembly includes
- at least a first extendable and retractable piston cylinder connected between the main frame and the tail assembly, and configured to raise and lower the tail assembly to the desired positon relative to the main deck;
- and
- at least one telescopic support arm connected between the main frame and the tail assembly, and configured to extend and retract in response to operation of the first piston cylinder, the support arm being further configured with a locking arrangement to retain the desired position of the tail assembly relative to the main deck.
The tail trailer of claim wherein the tail assembly includes a main tail having a rearward end and a forward end pivotally connected to the rearward end of the main deck, and a flip tail having a rearward end configured to engage the ground surface and a forward end pivotally secured to the rearward end of the main tail, the flip tail being movable between a folded position beneath the main tail and an unfolded position extending outwardly from the rearward end of the main tail.
A tail trailer supported for movement on a ground surface, the trailer comprising:
- a main deck mounted on a wheeled main frame and provided with a forward end and a rearward end;
- a main tail having a rearward end and a forward end pivotally connected to the rearward end of the main deck;
- a flip tail having a rearward end configured to engage the ground surface and a forward end pivotally secured to the rearward end of the main tail, the flip tail being, movable between a folded positon beneath the main tail and an unfolded position extending outwardly from the rearward end of the main tail;
- a lifting and holding assembly connected between the main frame and the main tail for pivotally moving and maintaining the main tail and the flip tail in a desired position relative to the main deck;
- and
- a combined locking and supporting arrangement mounted beneath the main tail and configured to provide ground engaging support for the main tail when the rearward end of the flip tail engages the ground, and to provide locking engagement with the rearward end of the flip tail when the flip tail is in the folded position beneath the main tail.
A tail trailer used in loading and unloading operations, the trailer comprising
- a wheeled frame having a forward end and a rearward end;
- a main deck mounted on the wheeled main frame and provided with a forward end and a rearward end;
- a tail assembly having a rearward end adapted to engage a ground surface and a forward end pivotally coupled to the rearward end of the main deck;
- an upper deck having a forward end adapted to be coupled to a towing vehicle, and a rearward end connected to a forward end of the wheeled main frame;
- a transfer deck having a pair of side members, a forward end lying adjacent the rearward end of the upper deck and a rearward end pivotally attached to a forward end of the main deck, the transfer deck being pivotally movable between a lowered stowed position serving as a coplanar extension of the main deck, and a raised loading position extending upwardly from the main deck to the rearward end of the upper deck;
- and
- a lifting system located between the main frame and the transfer deck, and configured with a sliding motion translating arrangement within the transfer deck for raising and lowering the transfer deck relative to the main deck.
