The system

Invented and constructed by one of the directors of Multi Haulage System Australia & manufactured by Twomeys Mining and Engineering, this system will revolutionize your haulage operations.

Road train trailer lined with a flexi tank enable the trailer to cart both solids and liquids.

Flexi tanks are manufactured from heavy duty rubber which is rated to carry liquids including oils and petroleum products.

Multi Haulage Systems increase chargeable freight and decrease freight costs to the customer. This is achieved by the truck being fully loaded both to and from any destination. Any truck can transport a load of fuel and then back load with nickel for example.

Our system is widely used throughout Western Australia and Queensland.
