• A drawbar livestock carrier I An Aussie-built low loader ith hydraulically-widening 'heel-track, decks and ramps proving quicker, quieter and tore stable to operate than uropean trailers says haulier /esmond Hollingworth, who nported it last November. The 13.1m tri-axled semi ith its 9.14m load bed travels closed up" at 2.5m wide for ormal C&U use. When eavier, wider loads need lifting under the Special 'ypes rules, each side deck, 3mplete with wheel stations nd hydraulic suspensions, loves out from its centre )ine along I-beam ribs. Power for this operation is ipplied by an underslung .7kW (4.6hp) two-stroke ngine (battery power is an ption) and the vehicle is 'lowed to roll slightly to :duce tyre scrub as the decks ush out to widths of 2.74, 05 or 3.35m where a series of neumatic locks hold them in osition.
Adjusting both sides and Ming the ramps takes 2-3 tinutes.
Its hydraulic, trailing-arm Ispension is a dampened iad-sharing system that can Is° be raised or lowered to emount loads, or each side in be moved separately to egotiate obstacles. It allows ver 220mm of vertical lovement which, says lollingworth, is considerably lore than conventional steel suspensions, and ensures that its 8.25x 15 tyres stay in contact with the ground, even over the roughest terrain. This makes it easier on tyres; hence its name —Tyresaver.
"Being able to adjust the wheel track as well as the load bed to suit the load provides a safer, more stable platform on which to travel, too," says Hollingworth.
Double-hung ramps extend hydraulically, giving a 12° rise to the 965mm-high deck. The tri-axled Drake semi with its 18-tonne oscillating king pin will take a 40-tonne payload with ease and has a 50% safety margin, he adds. -Its neck is capable of taking 50 tonnes at least," and four-axled versions
will carry much higher loads.
Changes to meet UK requirements include the repositioned air valves to ensure equal and simultaneous supply to the brakes. Type approval is imminent and Hollingworth plans to market both models in the UK under licence.
