VicRoads is now issuing single-trip permits to tow a platform trailer using a gooseneck coupling.
According to VicRoads, says operators can now apply for a single-trip permit to use the coupling when towing a 12-axle platform trailer.
“Recent advances in heavy vehicle technology, including the use of higher tensile steels and a greater emphasis on computer simulations mean that trailers with gooseneck connections are now far more stable than they were in the past,” VicRoads said.
“Consequently, operators can obtain a single trip permit to tow a platform trailer using a gooseneck coupling connected to a prime mover and operating with up to 12 lines of axles on the trailer on specified routes at specified axle limits.”
Operators can now obtain a permit for travel on suitable specified routes at specified axle mass limits, provided that the coupling is a height-adjustable gooseneck so that the platform can be made level prior to the commencement of travel; all axles on the platform trailer load-share; the trailer does not exceed the operating specifications set by the manufacturers with regard to maximum loads, speed and the number of rows (axles) that can be safely connected to the gooseneck connection; the laden trailer mass is not be towed in excess of 70km/h; and the gooseneck/platform configuration is arranged in a three-point connection.
A tandem-axle dolly fitted between the prime mover and the gooseneck trailer may also be used.
Meanwhile, the National Heavy Vehicle Regulator (NHVR) welcomed the new policy. “The NHVR supports this improvement in Vicroads' policy, and will continue to work with all jurisdictions towards greater harmonisation of future policies,” the NHVR said.
