Alko AKS Stabiliser Towball Adaptor Plate

Description

Alko AKS stabiliser towball adaptor plate.

Designed for use on 75mm wide towbar tongues.

*Towball not included.

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 appropriate spare parts should be fitted to your tow vehicle if you have purchased a new or second hand
caravan that has an AKS stabiliser coupling and you have not been supplied the special AKS 50mm towball and
retention plate.
