Product guides and example photos describe manufacturer configurations. They are separate from live inventory; confirm the actual trailer’s build sheet and availability with sales.

Explore the lineup

Start with how the load gets on.

Alpha HD’s commercial and construction ranges use different necks, deck layouts and loading arrangements. These are the main choices to discuss before narrowing the model.

Construction equipment & front loading

Hydraulic detachable lowboys

Compare the hydraulic neck, usable well, deck height and rear axle arrangement as a complete system. The construction range includes the A110HDG-SF and dedicated low-deck and higher-capacity configurations.

Models to discuss

A110HDG-SF · A110HDG-SF-18 · A120HDG-SF2

Check the fit

What are the machine’s weight, ground clearance and transport height?

Commercial freight & low-deck work

Mechanical double drops

The A80MG uses a mechanical gooseneck, with an air-assisted support arm and a low main deck. Compare the coupling process, tractor compatibility and loading access against the hydraulic alternatives.

Models to discuss

A80MG · A80MG-P · A90MG

Check the fit

How will you load it, and does the neck arrangement fit your tractor and operating routine?

Low-clearance paving equipment

Paver loading configurations

A tapered front deck and adjustable-width flip ramps change the approach onto the trailer. The A110HDG-SF-PAV is a dedicated hydraulic-detachable reference for this loading job.

Models to discuss

A110HDG-SF-PAV

Check the fit

Will the paver clear the ramp, taper and deck transitions at its actual operating weight?

Long loads & changing support points

Extendable double drops

An extendable well gives you more length, but the load’s support arrangement matters as much as the opening. Compare mechanical and hydraulic versions, closed dimensions and the rating for the extended position.

Models to discuss

A80MG-E · A80HDGC-E · A90HDGC-E · A110HDG-E

Check the fit

Where will the load be supported when the deck is open?

The full combination

The trailer is one part of the plan.

Axle additions, neck geometry and deck details need to work with the tractor and the load. Give sales the complete picture before choosing a model or attachment.

  1. Load dimensions and concentration

    Bring the weight, length, width, transport height and the distance between support points. A distributed rating and a rating over a short deck span are different references.

  2. Neck, deck and loading clearance

    Compare kingpin position, tractor swing, fifth-wheel height and deck height. Include the machine’s approach and breakover clearance.

  3. Axles and attachments

    Discuss flip axles, spreader bars and jeep dollies only with the matching trailer connections and a route-specific load plan.

  4. Timing and ownership

    Include the delivery location, target date, trade-in and financing needs. Sales can then confirm configuration, pricing and sourcing options.

Questions before you choose.

Are the Alpha HD trailers pictured here in stock?

The photos show example equipment and model configurations. Current Western listings appear separately in the live inventory section. If no units are listed, contact sales to check sourcing options and timing.

Should I choose a mechanical or hydraulic gooseneck?

Start with the loading method, tractor setup and coupling routine. Alpha HD offers mechanical double drops and hydraulic detachable configurations; sales can help compare the usable deck, clearance and neck arrangement for your application.

Can a flip axle, spreader bar or jeep work with any trailer?

No. Alpha HD describes these attachments for trailers designed to accept them. Confirm connections, ratings, geometry and the whole combination before selecting an attachment. An axle addition does not automatically establish a legal payload.

What should I include in a quote request?

Send the equipment or freight, weight and dimensions, loading method, tractor information, routes, delivery location and target date. Include a model or drawing if you already have one. Western will confirm the quoted build and availability.
