FACTORS IN TRAILER STABILITY AND SWAY
Incorrectly loading your trailer can contribute significantly to stability and sway related issues. Ensuring the load is distributed evenly as per the ‘sensible loading’ diagram on the previous page is key to minimising any instability. It is also important to consider the effects of loads such as luggage and portable fridges on the towing vehicle.
Incorrect tyre pressures on both the trailer and tow vehicle may in some cases lead to instability on the road.
External factors such as cross winds and overtaking trucks and buses can also cause significant sway and instability whilst towing.
There are several sway control devices commercially available which may aid in reducing trailer instability.
Note: Sway control devices are not appropriate for overcoming instability caused by vehicle loading or tyre pressures – these should be addressed by reloading the trailer and/or correctly inflating tyres.
AKS 3004 STABILISER
With this device, friction pads apply a high level of pressure on the tow ball. Their high damping force resists sudden movements, either horizontally or vertically to stabilise the caravan when being towed. This stabiliser must only be used with an anti-rotating tow ball.
ELECTRONIC STABILITY CONTROL
This is an electronic stability control system (ESC) which automatically applies the electric brakes, in a controlled manner; to a trailer should sway or a severe manoeuvre occur. This slows down the caravan and stops the sway from increasing.
FRICTION SWAY CONTROL
This is a device of universal application to all caravan/trailer combinations regardless of tow ball weight or coupling height. It is adjustable to accommodate small to large rigs and normal to severe highway conditions.
DUAL CAM SWAY CONTROL
This is applicable only to caravan/trailers having heavier tow ball weights. Whereas the Friction Sway Control is adjustable, the Dual Cam has a fixed setting.
The guidance of an experienced installer is advisable with any of this equipment.
