The Air Lift Axle is an assembly that uses an air spring (or springs) to lift an axle off the ground. This feature is generally used when the lowbed trailer is empty. Proper use of an air lift axle can reduce tire wear and provide better trailer maneuverability due to a shorter turning radius.

The Air Ride Suspension has a flexible air cushion pressurized by the tractor's air system and regulated by a leveling valve. The Air Ride Suspension is a popular choice for multi-axle gooseneck trailers. Air Ride Suspension provides a smoother ride and can be positioned for different axle spacing (i.e. 50", 54", 60"). When combined with a mechanical height control, the rear frame can be raised/lowered 3 inches (+ or -). Available in 25,000 lb. and 30,000 lb. capacities.

Autolock Pins are a safety device that is an important part of all ROGERS Ultima series goosenecks. The purpose of the Autolock Pins is to prevent the mating hooks on the gooseneck and the deck (beam hooks) from becoming disconnected when the trailer is in operation. The movement of the Autolock Pin in and out of position is done with a linkage connected to the gooseneck trapdoors. When properly positioned, the Autolock Pins rest in a notch in the interior surface of the gooseneck hooks. If the Autolock Pins do not properly position themselves in the notch it means the linkage has probably been bent and should be repaired or replaced.

An Automatic Slack Adjuster (Autoslack) is a component in the braking system on every ROGERS trailer. It provides the connection between the brake camshaft and the air brake chamber. The Automatic Slack Adjuster makes continuous adjustments to ensure consistent braking force as the brake linings and drum wear over time. Like all brake components, the Automatic Slack Adjusters require periodic maintenance to ensure proper function.

The Auxiliary Lighting System (also called an Safety Light Package) is a patented device that flashes the trailer lights whenever the electrical power from the tractor becomes disconnected. It is especially useful when loading or unloading the trailer at night, providing safety lighting for the trailer frame when the gooseneck is detached. Power for the unit is provided by a 12-volt battery which is stored in the deck of the trailer and receives a trickle-charge from the main electrical system when not in use.

Installed underneath the cross members in the center of the deck, the Bar Grating creates a self-cleaning area to hold chains, binders and blocks.

A Beam Hook is a component welded to the front end of each of the main beams of a ROGERS detachable gooseneck trailer deck. The shape and thickness of a trailer's Beam Hooks depends on the style of detachable gooseneck (Ultima NoFoot or CobraNeck) and the capacity of the trailer. The Beam Hooks mate to the gooseneck, either to a Cheek Plate Hook or to a shaft, to form the main connection securing the gooseneck to the trailer deck.

The Beavertail (sometimes called a Dove Tail) is a sloped extension on the rear frame of a trailer to allow equipment to be loaded over the rear of the trailer - with or without the use of rear ramps. Most all ROGERS fixed gooseneck and tag-along trailers include a Beavertail. A Beavertail is also available as an option on certain ROGERS detachable gooseneck models and is used for loading when it is not convenient to detach the gooseneck for the front loading of equipment.

Bent Lashing D's are structurally similar to standard Lashing D's except the bottom half of the D is forged at a 55° angle so that securing chains do not pinch against the side beam flanges of the trailer. The working load limit (WLL) of the 1" diameter Lashing D (properly mounted) is 15,000 lbs.

The Boom Trough is an area between the rear frame beams where the frame is modified so that a "trough" is created. The open space in the Boom Trough can hold the boom or stick of an excavator helping to reduce the overall height of the loaded machine. The carrying capacity of the trunnion outriggers is reduced in this application.
