In the 1980s Elphinstone designed and built the World's first non-hydraulic folding skeletal trailer and the first Elphinstone B-Double.

The 1990s saw the emergence of a number of innovative designs including special heavy duty Tandem trailers for Tanzania (Africa); the first Elphinstone self loading Tri-Tri B Double; some special purpose trailers to cart Zinc; a special purpose 'Sandgroper' log trailer for use on Bribie Island; built our first hydraulic folding Skel; developed the Elphlink log Jinker; built the first Easyloader™ Tri-Tri B Double, and the first Easyloader™ Tandem-Tandem B Double. This decade also saw the export of B-Doubles and the introduction of on-vehicle weighing to South Africa; the introduction of air suspensions to our trailers, and introduced Tandem and Tri-axle Jinkers to the rear of Easyloader™.

The next decade saw more innovation with the introduction of the World's first Easyloader™ self loading B-Triple; self-loading road train and the Long Logger B Double which is capable of carting 19m loads in a single length. Designed and built a range of pole trailers from single axle up to three axle self-steering, including an extendable pole trailer for multiple length poles.

Elphinstone continues to be at the forefront of innovative design with the Easysteer™ suspension which will increase payload and deck length and provide very accurate on-vehicle weighing.
