Standard Features
-
- Air Operated Locking Pins
- A large pin on each main beam secures the sliding components in the desired position. Each pin is operated by an air mechanism that is controlled from a single central location.
-
- Deck Height
- The operational deck height is 43” while using a larger tire and taller ride-height suspension. A low deck height option is available.
-
- Extendable Lower Deck
- Extending the lower deck by 17’ provides a 57’ lower deck space (68' overall) to transport a self-supporting cargo load
-
- Flanges and Webs
- 100 KSI grade high-strength steel
-
- Hendrickson HT250 Suspension
- HT250, 9” ride height, 5/8” wall axle, enclosed camshafts
-
- Kicker Rolls
- Two 6" kicker rolls can be raised above deck level to make loading a single self-supporting structure easier
-
- Knee Braces
- With knee braces set 2' apart, loads extending outside the main beams can have the weight efficiently transferred to the main beams
-
- Narrow Pick-Up Throat
- Narrow throat makes access easier
-
- Override Valve
- The suspension is equipped with a second height control circuit that can be used to raise and lower the deck for loading and unloading
-
- Pin Pockets
- Pin pockets located along the sides provide a guide for the cargo that is being pulled onto the deck from the rear
-
- Rear Bolster Set-Up
- The rear bolster is designed to accommodate a booster and comes equipped with a complete set of electric and air hook-ups to make the connection
-
- Rear Live Roll
- The 8 3/4" live roll extends across the full width of the trailer
-
- Steel Checker Plate Fenders Over All Tires
- Steel checker plate fenders prevent trash from damaging cargo and they provide a sturdy and flat surface to work on
-
- Swing-Out Wide Load Lights and Flag Holders
- Both the lights and the flag holders provide the necessary warnings to indicate an over-dimensional vehicle and load
-
- Upper-Deck Dead Roll
- A dead roll is located at the top of the drop
-
- Wide-Load "D" Sign
- The wide-load sign is removable for loading cargo and can be placed on the trailer as shown or moved to the booster when it is added to the rear of the trailer
-
-
Options
-
- Cross Chain Eyelets
- Cross chain eyelets provide additional securement points to help prevent the rear of an over-dimensional load from moving sideways
-
- Heavy Duty Belting at Drop
- Belting ahead of the drop prevents mud and rocks from being propelled against the drop and landing gear legs
-
- Low Deck
- An optional 37" deck height is available in conjunction with 17.5" tires
-
- Pull-Out Outriggers
- Outriggers increase the deck surface of the trailer to accommodate cargo that lacks sufficient structural support while being transported
-
- Rebound Chains on Each Axle
- Rebound chains prevent the airbags from over-extending, which could cause them to fail
-
