DIN 9021 8.4
In addition to using the recommended Coupling, ensure fixings are secure and appropriate for the anticipated loads. We recommend the use of
Fastening Set 8 6-8 (0.0.684.91). When using Coupling D25-610, 2 steel Washers DIN 9021 8.4 should be added to the Fastening Set.
Drawbar Coupling D25-74 (0.0.661.87)
Drawbar Coupling D25-30 (0.0.674.28)
Take note of the maximum load-carrying capacity of the fasteners and profiles (item24.de/en).
For example, consider a standard Line 8 profile combined with Fastening Set 8 6-8 (0.0.684.91):
Groove load-bearing capacity: 5000 N per fastening point
The maximum load-carrying capacity of the connection between the aluminium profile and Drawbar/Coupling can be increased by drilling through-
holes and using M8 screws in an appropriate length along with suitable washers and nuts. This through screw arrangement makes the connection
between the Drawbar Coupling and the frame of the transport trolley more rigid. This may result in damage being caused to the basic frame of the
trolley in the event of a collision.
Incorrect commissioning and operation can result in malfunctions that can adversely affect service life and pose a risk to personnel.
If the Drawbar is returned to the upright position in an uncontrolled manner, it can pose an injury hazard as it rights itself by spring force. Before under-
taking any journey, check all coupled trolleys to ensure the Drawbar and Coupling are correctly engaged.
• When using the self-lifting Drawbar variant, the pin of the Coupling must point downwards.
• After installing the Drawbar, carry out a test run somewhere that is free from hazards but outside the area where the product will be used.
• The Drawbar should be installed so that the tensile load is transmitted parallel to the roadway.
– Where operating conditions mean it is not possible to ensure parallel load transmission, the maximum trailer load calculated earlier must be
reduced as per DIN 15172.
– We recommend that the vertical deflection of the drawbar to the level of the floor under operating conditions should not exceed 5% of the
drawbar length. (VDI 2406).
• Use the correct combination of Drawbar and Drawbar Coupling.
– Drawbar D25-686, Self-Lifting and Drawbar Coupling D25-74 (0.0.661.87)
– Drawbar D25-610 and Drawbar Coupling D25-30 (0.0.674.28)
