Product Description

The extendable flatbed semi trailer uses a telescopic main-beam structure that allows the loading platform to increase in length when required. After the long cargo is delivered, the trailer can be retracted for easier empty return and storage.

Telescopic trailers require detailed engineering because extension changes the wheelbase, turning path, frame stress and load distribution. The cargo should be supported at defined positions, and the operator must follow the approved extension and securing procedure.

AOHA can customize the extension range, locking positions, rear steering arrangement, support bolsters and cargo-securing points around the transported product. Typical applications include long pipes, bridge components, prefabricated structures and selected energy-industry equipment.

Typical Applications

━━━━

Long steel beams and bridge components
Pipes, columns and prefabricated structures
Wind-energy and utility components within design limits
Long industrial machinery frames
Oversized cargo requiring adjustable deck length

Key Advantages

━━━━

Telescopic Deck Length

The platform can extend for long cargo and retract for empty travel.

Cargo-Specific Support

Bolsters, posts and support locations can be positioned around the load drawing.

Improved Return Efficiency

A retracted trailer is easier to maneuver and may reduce empty-return length.

Heavy Structural Locking

Mechanical locking positions hold the telescopic beam at approved extension stages.

Optional Steering Support

Steering axles or hydraulic steering can be considered for long-wheelbase applications.

Integrated Securing Points

Heavy lashing rings, stake pockets and chain anchors can be installed along the deck.

Quality Control and Delivery

━━━━

Testing should verify telescopic movement, locking-pin engagement, frame alignment, steering response, brake operation and lighting at each approved extension position. The customer should receive an extension chart and loading instructions tailored to the final design.
