Common use of Drawbar couplings Clause in Contracts

Drawbar couplings. 3.3.1. Clevis-type couplings (Class c) A dynamic endurance test shall be carried out on a sample. The coupling device shall be equipped with all the fixings needed to attach it to the vehicle. 3.3.1.1. For rigid drawbar trailers Dynamic pulsating endurance test within the range for pulsating tensile stresses with resultant test force (direction of pull rearwards and down) As in paragraph 1.7. of this annex. 3.3.1.2. Clevis-type couplings on trailers Loading assumptions taking into account the D value is used. R1 and R2 as specified by the manufacturer (R2 · R1). Dynamic endurance tests as in paragraph 3.3.1.1. of this annex. 3.3.1.3. Static tests on locking device for coupling pin With clevis-type couplings with non-cylindrical pins, it is also necessary to test the closure and any locking devices by means of a static force of 0.25 · D acting in the direction of opening. A test force of 0.1 · D is sufficient in the case of cylindrical coupling pins. This force shall be raised to the above value smoothly and quickly and be maintained for 10 seconds. The test shall not cause the closure to open and it shall not cause any damage. 3.3.2. Hitch hooks (Class g) As in paragraph 3.3.1. of this annex. 3.3.3. Tractor drawbars (Class i) 3.3.3.1. Either as in paragraph 3.3.1. or a static test instead of the dynamic test as described in paragraph 3.3.
