WS 3000 – Fitting and Operation Instructions
Safety Coupling with Stabiliser:
Type
WS 3000-D
WS 3000-H
WS 3000-L
WS 3000-LB
WS 3500-D
WS 3000/3500 Safety Couplings with Tracking Stabiliser have been tested in accordance with the di-
rective 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 rolling movement by the trailer. Optimum damping is achieved with new
friction pads after running-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 pursuant to DIN 74058 / ISO 1103).
Using the WS 3000/3500 is not permitted in connection with ball pins with screw fastening
without additional form-fitting retainer (Fig. 2). With the stabilizer connected, the opera-
ting 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 simultaneously 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
crossways screw connection (1)+(3) and 40 mm hole spacing (Fig. 3). The fastening mate-
rial is not included with the product.
