Interstate Trailers® Tri Axle Heavy Duty Tag Trailer to suit Excavators, Skid Steer Loaders, Compactors, Wheel Loaders, Dozers & more.

100% Australian Manufactured. Road Tested & Contractor Approved.

Why buy a used or a light duty tag a long beaver trailer when for not a lot more money you can get one of our Heavy Duty Manufactured INTERSTATE TRAILERS. These units are 100% Australian manufactured – “Road Tested and Contractor Approved”.

We always have 5+ units in stock and ready for same day shipment Australia Wide.

We don’t attempt to re-invent the wheel but just do it better than the rest. Our local manufacturing team have been manufacturing beaver tail and tag plant trailers for over 20 years with a proven design and quality that is not surpassed but often copied by others in the industry. Unlike others in the industry we do not get the trailer bases / skeleton units manufactured in countries such as Thailand or China, using out of gauge lower grade steel and then have them cheaply shipped into to Australia, and add axles and wheels to call them Australian manufactured.

We also DO NOT use bait advertising and sales techniques of ”smokes and mirrors” on advertising poverty pack base unit trailers. This is a old industry trick just to get your sales call so that $3K to $7K worth of extra options can be added onto the sales price at time of order to get you into a heavy duty specification trailer after you have committed with a deposit. With Interstate Trailers, what you see advertised is the exact trailer specification you will receive, and don’t forget Interstate trailers are road tested and contractor approved.
