Sometimes referred to as a stretch step deck or stretch flat drop, this trailer is a composite (or Combination – Combo) structure of high-strength steel and aluminum.
The full-width, hollow-core, aluminum flooring is also a structural member. In addition to having a stepped frame, this trailer can be extended to conform to long loads. Rollers in the frame rails allow the unit to be extended or retracted with ease. There are numerous locking points along the trailer to give the operator the flexibility to choose how much to extend.
The frame is also full-depth throughout the trailer. This means that the axles are installed through the main beam instead of under it. This composite frame and through axle design are the keys to the trailer’s low tare weight and incredible stiffness.
The flagship feature on this unit is the ability to remove the extendible beam insert. When this insert is removed, the trailer effectively becomes a standard flatbed. This feature makes the trailer more versatile as it is still competitive on weight as a standard flatbed.
The rear deck height over the wheels is the lowest possible height given the clearances for the suspension and flooring requirements. This low height requires the use of fenders that protrude from the deck. The bottom deck section slopes progressively downwards where it meets the gooseneck to give an impressive loading height of 28 inches in that area.
The smooth underside of the flooring reduces the amount of snow and mud that can accumulate. High point loads on the outer rails are met with ease as the aluminum flooring is 3x stronger than the traditional steel deck construction.
