WS 3000 / WS 3500

stabiliser couplings for braked trailers up to 3,500 kg

Increased lane handling and safety

The WS 3000 and WS 3500 stabiliser couplings for braked trailers up to 3500 kg with specially developed friction elements are pressed axially under the high spring pressure against the towball of the vehicle, resulting in the enormous stability of the vehicle combination. As a result, the critical speed at which a vehicle combination becomes unstable and starts to yaw is permanently increased by up to 30%. The WS 3000 / WS 3500 couplings fulfil the ISO 11555-1 standard and are therefore approved stabilisation devices for the 100 km/h regulation.

Why does my WS 3000 / WS 3500 make noises while driving?

Due to dirt, paint or rust on the ball, the WS 3000 / WS 3500 may make noises during driving. The ball head of the vehicle must be metallically bright prior to being driven for the first time. To reduce the noises, you can carefully sand the ball head with sandpaper (200 - 240 grit) and then clean the head with paint thinner or brake cleaner. The friction elements should also be cleaned in this way. If an improvement does not occur after cleaning, replacement of the friction elements is recommended.

Is there a spare handle for the WS 3000 / WS 3500?

The handle of the WS 3000 / WS 3500 is not envisaged as a manoeuvring aid. If the handle becomes broken, it can be easily replaced.

What causes problems when uncoupling the WS 3000 / WS 3500?

If problems occur when uncoupling the WS 3000 – WS 3500, it should be checked that the overrun device is not tensioned. It must not be subjected to tensile or pressure loads, i.e. the bellows should be extended as much as possible.

Why can the WS 3000 / WS 3500 turn to the side during driving?

The WS 3000 / WS 3500 is tightly bolted to the drawbar tube or overrun brake. The tube of the overrun brake can be turned to the side, meaning the unit may tilt to the side during the journey. However this does not negatively impact the function.

Is TÜV entry required following mounting of the WS 3000 / WS 3500?

The WS 3000 / WS 3500 has EC approval, a TÜV entry is therefore not required.
