Dual Cam High-Performance™ Sway Control
Unlike other sway controllers, this approach works to control sway from the start rather than just resisting sway once it’s begun. When towing in a straight line, the spring bars on either side of the trailer’s A-frame are locked in position. This essentially creates a “rigid” connection between tow vehicle and trailer and minimises the effects of induced sway caused by high crosswinds or passing vehicles. Usually the spring bars ride in a locked-in position, even on fairly sharp curves.
However, when cornering manoeuvres are required, the cams automatically slide out of their fixed position to permit full radius turns. Yet when the manoeuvre is short and abrupt, like that encountered in the event of a sudden swerve or a wheel dropping off the road, the spring bars seek a straight-line towing angle that helps the tow vehicle retain control.
The advantage of the Dual Cam system is its ability to prevent sway in addition to sway resistance. It works to hold down the start of swaying activity while at the same time allowing free and easy vehicle and trailer interaction. Another advantage of the Dual Cam system is that it’s installed on the trailer and therefore doesn’t require adjustment every time the towing vehicle and trailer are hooked up, unless hitch weight or tow vehicle loading are changed.
The Dual Cam HP is fitted in conjunction with any Heavy Duty Hayman Reese Weight Distribution System that includes high performance spring bars with Cams. It is ideal for any trailers with a ball weights in excess of 200kg.
