For purposes of EN 12641-2, this attachment should be effected by the use of a welding process. 3.3 Tarpaulin reinforc

26、ements Curtainsider tarpaulins shall be reinforced by vertical and horizontal belts. The belts shall be secured to the tarpaulin. NOTE A suitable method of securing the belt to the tarpaulin is by welding. However, other methods may be used if they provide an equivalent performance. The vertical and

27、 horizontal belts shall be arranged at intervals of 600 mm. The total number X of the vertical belts shall at least be equal to the arithmetic mean in accordance with the following equation: 550550=LX (1) where L is the length of the body; all values, in mm. The belts shall meet the following requir

28、ements: vertical belts: tensile strength 23 kN; horizontal belts: tensile strength 12 kN.

The belt hooks of the ve

29、rtical tensioning belts shall remain in vertical position when the belt is slack and shall meet the functional dimensional requirements of Figure 1.

31、oning devices shall be clear and obvious. The hand levers for belt tensioning shall be in positive engagement in the closed position. To release the hand lever it shall be necessary to unlock it first by actuating a separate unlocking device. Belt tensioners which are at least equivalent in function

32、 and safety are also admissible. The belt length between the belt hook and the upper deflection point of the belt tensioning lever should be at most 350 mm. NOTE If the swap body is equipped with grappler plates, the value of 350 mm may be exceeded within this specific area. Tensioners which work wi

33、thout belts and which are at least equivalent in function and safety are also admissible.

34、the tarpaulin. The ends of the tarpaulin shall be framed by a rod of metal or similar material. On the swap bodies side this rod is hooked on and on the opposite end it is tensioned by means of a tensioning device. In general, horizontal tarpaulin tension is achieved by turning and thereby coiling t

35、he tarpaulin material at the tightening end. The tensioning mechanism shall be self-locking. Alternatively, if self-locking is not provided, there shall be a different locking system for the hand lever which is secured against unintentional release and the actuation of which shall be clear and obvio

36、us. 3.5.4 Testing 3.5.4.1 General Testing in accordance with 3.5.4.2 and 3.5.4.3 is intended to demonstrate a minimum strength of the vertical belt system. For this purpose, a segment of belt and tarpaulin of 500 mm to 600 mm in width and 2,9 m to 3,0 m in length (measured from the roller to the hoo

37、king-on point of the tarpaulin) with a tensioning device fitted at the centre shall be used. If, in general, the lateral height of the tarpaulin is 2,5 m the test can be carried out with a tarpaulin that is appropriately shorter. The top roll guide and the hooking on of the lower end of the tarpauli

38、n shall be constructed as in the original test specimen to be used later. The tarpaulin shall be fitted with its upper and its lower reinforcement; the horizontal reinforcements in the middle may be omitted for testing. Technically comparable test fixations are admissible. 3.5.4.2 Static test The be

39、lt segment described under 3.5.4 shall be attached to the top roller guide of a test device and shall be submitted to a vertical test load of 4 kN. For the whole system to set, the test load is applied for a period of 30 s after which the load is taken off and a reference zero measurement is carried

40、 out. If no damage has occurred the test load is again applied for a period of 5 min. After the test there shall be no permanent change in the position of any of the components 5 mm in relation to the zero measurement nor any other alterations that would impair the function, in any of the individual

41、 components of the system. 3.5.4.3 Dynamic test A second specimen shall be prepared as described in 3.5.4. The test apparatus shall be constructed as set out in Figure 2. The roller of the tarpaulin to be tested is introduced into the top roller guide. At the bottom end, the belt hook is hooked on i

42、n the zero position of the eccentric tensioner and tensioned by hand. In this position, the test equipment is able to execute oscillating travel of 15 mm. The lower part of the tarpaulin fixation is tested as follows, using oscillations of 15 mm: a) 1 min at 4 Hz, after which retension the belt and

43、mark the position of the tensioning belt, the eccentric drive being in zero position. b) 2 min at 4 Hz. c) 2 min at 12 Hz.

44、requirement shall be fulfilled with the belt hook in the zero position of the eccentric drive: the belt shall at least still have a slight residual tension, i.e. a slack belt is not admissible; the tensioning belt shall not slip through more than 5 mm on the tensioning lock.
