WS 3000/3500 Safety Couplings with Tracking Stabiliser have been tested in accordance with the
directive 94/20/EC and comply with ISO/11555-1 as amended on July 1, 2003, and have therefore
been approved for use up to a maximum permitted speed of 100 km per hour (kph).
Keep the Fitting and Operation Instructions with you when using the trailer.
1. Technical Features
1.1 WS 3000/3500 safety couplings with tracking stabiliser are suitable for use with centre-axle
trailers with an effective minimum weight of the trailer of 200 kg.
1.2 The ball coupling is fitted with spring-loaded friction pads which surround the ball coupling
of the towing vehicle from the front and the rear. This reduces or prevents any pitching and rol-
ling movement by the trailer. Optimum damping is achieved with new friction pads after run-
ning-in for a certain period of time.
1.3 WS 3000/3500 ball couplings can only be used with coupling balls pursuant to DIN 74058 / ISO
1103 if the ball neck is free from fittings over a distance of 35 mm (Fig.1) (instead of 32 mm pur-
suant to DIN 74058 / ISO 1103).
Using the WS 3000/3500 is not permitted in connection with ball pins with screw fastening wit-
hout additional form-fitting retainer (Fig. 2). With the stabilizer connected, the operating lever
may not come into contact with the vehicle or attachments in driving mode, i.e. it must not collide
with the handbrake lever or any other attachments whilst pushing in the towbar and simultane-
ously turning the WS 3000/3500 (Fig. 5). The overrun brake manufacturer's operating instructions
and information must also be observed.
2. Assembly
2.1 The WS 3000-D ball coupling can be used universally and is suitable for the following drawbar
connections:
Drawbar connection 50 mm – without spacer plate
Drawbar connection 46 mm – spacer plate 2.0 mm (included)
Drawbar connection 45 mm – spacer plate 2.5 mm (included)
Drawbar connection 40 mm – spacer plate 5.0 mm (included)
Drawbar connection 35 mm – spacer plate 5.0 mm + 2.5 mm (included)
The WS 3000-D ball coupling can be fitted with hole spacing of 50 or 54 mm (1)+(2) for lengthways
screw connection and with hole spacing of 40 mm (1)+(3) for crossways screw connection:
Hexagon head bolt M12 x 90 with washers on both sides and self-locking nut for oblong hole (1)
Hexagon head bolt M12 x 80 for lengthways screw connection with self-locking nut (2) or for
crossways screw connection with self-locking nut (3) and stop (4).
The fastening material (1, 2, 3) is included; the stop (4) is not included with the product.
The WS 3000-H/L/LB are specially designed for inertia braking systems and are fitted with cross-
ways screw connection (1)+(3) and 40 mm hole spacing (Fig. 3). The fastening material is not in-
cluded with the product.
