An innovative convertible A­double combination trailer system has seen a big gain in load tonnages for a Victorian transport company.

The A­double developed by Maxitrans companies Freighter and Hamelex White is designed to maximise payload in a modular design.

Four of the combinations have been delivered to Portland-based company Porthaul for transporting woodchip, grain and fertiliser.

The Performance Based Standards approved combinations consist of Hamelex White aluminium tubs, similar to a standard grain tipper, mounted on lightweight skels with dollies to create a modular combination.

The innovative combination sees the front trailer ‘tip through’ the rear when emptying on a tipping ramp.

A sliding dolly allows the front trailer to be backed up directly onto the rear trailer.

The doors of the front and rear trailer then swing open together when the tipping ramp is raised to allow product to tip through from the front trailer and out the rear door of the rear trailer.

“These A­doubles can transport pretty much anything we want, from hauling wood chips, grain or fertiliser in the tubs, to removing the tubs to transport logs.

"We’ve diversified but haven’t had to add more equipment,” said Porthaul general manager James Williamson.

The A­double combination has also seen a significant weight gain having achieved a total of 81-tonne GCM ­ seven more tonne compared to the company’s previous quad Super B­doubles and 14 tonne more than a standard B­double.

“We have now maximised the total payload available to us on Victorian roads,” Mr Williamson said.

The trailers are also fitted with auto greasing, Electronic Braking System (EBS), central tyre Inflation and weight gauges.

“Most of the technology also helps improve our driver safety, like the weight gauges, which send readings directly to the driver via a display in the cab,” Mr Williamson said.
