The ALKO “AKS” range of stabilizing coupling heads is fitted as original equipment on most European caravans and some Australian and New Zealand caravans as optional equipment, where a 50mm towball is used.
The effective suppression of snaking movements of the caravan or trailer is achieved by 4 special friction pads which surround the towball and resist rotation.
AS A RESULT OF THIS DESIGN IT IS IMPERATIVE THAT THE 50mm TOWBALL USED ON THE TOWING VEHICLE IS UNABLE TO BE LOOSENED BY ROTATION.
Most tow vehicles within Europe use a rigid forged 50mm towball which is bolted to an attachment on the vehicle towbar. The fixing and retention of this style of towball is not affected by the friction clamping of the AKS style stabiliser.
However, most tow vehicles within Australia and New Zealand use a conventional towball which is most commonly fixed through the towbar tongue and retained by a washer and nut. This type of towball, when used in conjunction with an AKS style coupling head could become loosened by normal vehicle/caravan rotation during turning.
To eliminate this ALKO has developed, using an Australian Standard 50mm towball (with flats on the ball flange), a retention plate which stops the rotation of the towball during operation.
IT IS IMPERATIVE THAT ONLY A 50mm TOWBALL WHICH CANNOT UNWIND ITSELF BE USED WITH ANY AKS STABILISING COUPLING HEAD.
The AKS Tow-Ball Retention Plate is vital if you’re running the sway-reducing AL-KO AKS3004 Coupling in your rig, as without its extra support your tow-ball that is gripped by the AKS coupling will actually loosen completely off. Having the plate in place is recommended and will suit the standard 75 mm tow-bar tongue.
This towball is especially made to work with this system.
