A novel and simple anti-rollover device aimed at existing trailers has been designed by a former haulage company operator, running high and heavy loads, such as glass bottles and bridge sections.
John Wilson, of Messenger Direct, claims that his patent-pending device "operates on a little known force that affects many combinations in varying degrees [and] that we believe has contributed to many rollovers".
Wilson says that his system uses "ingenious geometry" on the fifth wheel to "counter the centrifugal forces in articulated vehicles" and hence lean the trailer slightly into a turn, in the event of heavy and potentially dangerous braking.
His design uses no sensors, actuators or hydraulics, he says, and is easily fitted to any existing trailer. "Also, it is very low cost, in comparison to any other innovation currently being offered to reduce the risk of overturning," states Wilson.
He also suggests that adjusting the 'turn to tilt' ratio is easy and is limited only by the body clearance. And he advises that his unit can also "accept a degree of electronic adjusting, using any ECU active data".
"My recommendation would be the fixed mode, since this would cater for practically all trailers. However, in my experience, [in] some exceptional terrain … there may be a case for slight adjusting to suit, so I designed the variable module [to be] adjustable in minutes by the driver," asserts Wilson.
"I am terrified by the thought that anyone thinks braking an artic abruptly in a turn is safe … let alone having them applied without driver intervention," says Wilson. "Further, if [big name braking companies] knew what happens in some circumstances they would agree, despite ESP."
It has been impossible for this journal to verify Wilson's claims in the face of his concerns about IP theft. However, Wilson insists that, if any IRTE centre or serious commercial concern is interested, he will provide a demonstration which he is "sure will bring in the most sceptical of engineers".
