A major advantage of the Sidewinder steering system compared to other Positive Rear Steer Systems is the quicker steer axle response in relation to the tractor unit. This is achieved due to the unique cam and roller module design.

A rear steer system will move in response to the tractor unit and as the graphic comparisons illustrate, a conventional steer system will turn directly with the tractor unit until it eventually reaches its full turning capacity when the tractor unit is at 90 degrees to the trailer. Consequently, the steer system is never achieving its full potential and is therefore less beneficial and effective than it should be.

The Sidewinder steer system enables the axle to achieve its full turning capacity when the tractor unit reaches an angle of only 40 degrees, much less than other conventional systems, this ensures that the trailer is utilising and benefitting from the steer system at all times. This system offers both a better steering angle and improved steering capabilities in everyday driving situations.

How This Happens

Because of the quick steering response in relation to the tractor unit, the front axles (s) are able to be situated further towards the front of the trailer than a conventional system. This in effect, shortens the rear pivot point on which the trailer will turn, in theory, shortening the trailer to give an even smaller turning circle for tight corners, junctions and restricted areas. The improved axle positions also provide a better load and weight distribution.

The system works at all times and is equally as effective in forward or reverse. So unlike other options such as rear lift axle, sliding bogie, self tracking steer etc., you are enjoying the benefit at all times.
