24、y the use of a welding process. 3.3 Tarpaulin reinforcements 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 th
25、ey provide an equivalent performance. The vertical and 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 va
26、lues, in mm. The belts shall meet the following requirements: vertical belts: tensile strength 23 kN; horizontal belts: tensile strength 12 kN. EN 12641-2:2006 (E) 6 3.4 Belt hooks Belt hooks for tarpaulins shall be made of flat material. The belt hooks of the vertical tensioning belts shall remain
27、in vertical position when the belt is slack and shall meet the functional dimensional requirements of Figure 1. Dimensions in millimetres all other dimensions at the discretion of the manufacturer Key aslit periphery on both sides without any burs bperiphery of outside edges without burs on both sid
28、es Figure 1 Functional dimensions of the belt hook 3.5 Tarpaulin sides 3.5.1 General During transport operations the tarpaulin sides shall be tensioned both in horizontal and in vertical direction. 3.5.2 Vertical tensioning devices The locking procedure for tensioning devices shall be clear and obvi
29、ous. 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 and safety are also admissible. The
30、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 without belts and which are at least eq
31、uivalent in function and safety are also admissible. EN 12641-2:2006 (E) 7 3.5.3 Horizontal tensioning devices The tarpaulin sides are closed at the front and rear ends of 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
32、 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 the tarpaulin material at the tightening end. The tensioning mechanism shall be self-locking. Alternatively, if self-locking is n
33、ot 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 obvious. 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 o
34、f 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 hooking-on point of the tarpaulin) with a tensioning device fitted at the centre shall be used. If, in general, the lateral height
35、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 tarpaulin shall be constructed as in the original test specimen to be used later. The tarpaulin shall be fitted with its upper and its l
36、ower 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 belt 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
37、 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 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
38、 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 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 sh
39、all 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 in the zero position of the eccentric tensioner and tensioned by hand. In this position, the test equipment is able to execute os
40、cillating 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 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. EN 12
41、641-2:2006 (E) 8 After the dynamic test described in a), b) and c) the following 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
42、 not slip through more than 5 mm on the tensioning lock. Dimensions in millimetres Key 1 drive approximately 4 kW 2 zero position Figure 2 Dynamic test configuration 4 Marking Side curtains that fulfil the requirements of this European Standard shall be marked durably with the following information
