COMBO DROP DECK TRAILERS

Jet has been manufacturing Combo Aluminum Drop Deck, Step Deck and Combo Aluminum Double Drop Deck trailers for over 20 years. Engineered for strength and performance, our combination drop deck trailers are comprised of two steel high strength fabricated beams. Every beam is designed as a continuous, one-piece assembly, and precision automation welded, this includes the beavertail of the trailer. Typical aluminum components include the cross-members, side rails, and front and rear ends of the trailer. This reduces the overall weight of the trailer, allowing for increased load capacity. Popular options for our combo aluminum drop deck trailers include sliding axles, triple and quad axles with lift kits, front bulkhead, beavertail, spring assist ramps, tool boxes, winches, and more. See the options tab to find even more options.

Beavertails are one piece construction and part of the main beam. They are not bolt on and cannot be added after the build. They can be configured in different lengths and angles, and finished with aluminum flooring, open aluminum rungs. Two Fabricated steel Spring Assist Hinged Ramps included. Ramps can fold "flat" to the main deck. Heavy Duty ramp option also available.

Axle configuration options include single, closed tandem, tandem spread, triple, triple spread, quadrupedal, or other options.
Either regulated or non regulated lift axles with control box. Can be installed for any axle in several combinations (Front, Middle and/or Rear)
Slider boxes are optional on closed tandems. Also the front or the rear axle can install as a slider on a tandem 10' 1” spread.

Aluminum wheels are available in Standard or Extra Polish. They reduce weight and provide a better visual appearance. Sizes include 8.25 x 24.5 or Wide Base Single Wheels

Regulates correct and equal tire pressure across all tires. Controls two axles. Triple axles will require and second system.

Installed in a weather resistant enclosure on the road side of the trailer by the front axle. Gauge reads pressure from the airbags. Filled with shock absorbing liquid to protect the gauge from vibration. Manual dump valve quickly releases the air from the air bags on the suspension.

Main Beam, Crossmembers, and Knee Braces can be configured for concentrated loads such as steel coils.

Options include slanted angle neck of 17º or 45º for easier use of the top deck. Lower deck heights and double drops are available if increased overall head clearance is required. Please contact our sales department. They will work with engineering to fulfill your needs.

A bulkhead can be added to the front of the trailer, either bolted on or mounted in welded stake pockets.

Aluminum tool boxes can be mounted outside the main beam, between the landing leg and front axle.

Assembly that drops into the stake pockets toward the middle and the rear of the trailer for a level surface to the top deck for loading long items.

The tail roll option is ideal for pulling skids onto the trailer.

Ramp Holders allow for a storage space of optional front ramps to the top deck

Twist locks are available for container securing

Sliding winches can be mounted the either the road or the curb side of the trailer on the side rails. Straps can be added for additional means to secure a load.

Rope hooks can be added for additional means to secure a load.

Recessed tie downs retract into the deck when not in use.

D-Rings can be added to the main or upper deck at custom locations.

Allows for storage of a spare wheel and tire

Three tail lights are standard. Four are optional. Increases the trailer visibility from the rear. Multiple configurations of marker lights are available to increase the trailer visibility in the dark. 3 per side are typical. Please contact your sales rep about options.

Galvanizing the trailer before the axles and landing legs are installed allows for extreme corrosion resistance in severe environments.

Stocking colors are black, slate gray and red, or custom matching to a tractor or company color is possible.
