O BSI 02-2001 STD-BSI BS EN LZb40-ENGL 2003 Lb24bb9 a895889 720 Page 4 EN 12640:2000 I Scope This standard specifies the minimum requirements and
19、test methods for lashing points fitted to commercial vehicles and trailers with flatbed body construction of maximum total mass above 3,5t and intended for general use. The standard does not apply to: - vehicles designed and constructed exclusively for the transportation of bulk materials; - vehicle
20、s designed and constructed exclusively for the transportation of specific cargo with particular securing requirements. 2 Terms and definitions For the purpose of this standard the following terms and definitions apply. 2.1 lashing point securing device on a vehicle, to which a lashing may be directl
21、y attached A lashing point can be e.g. an oval link, a hook, a ring, a lashing shoulder 2.2 lashing equipment device designed to be attached to the lashing points in order to secure the cargo on the vehicle. The lashing equipment consists of tensioning elements (e.g. belt, chain, cable), tensioning
22、device (e.g. wrench, ratchet, spanner, tension jack) and connections, if required (e.g. hook, eyelet) 2.3 angle of inclination U angle between a vertical line through the lashing point and the direction of application of the lashing force (see Figure 1) 2.4 Angle of rotation u smallest angle between
23、 a plane through the lashing point parallel to the vehicle?s longitudinal centre plane and a vertical plane through the direction of application of the lashing force (see Figure I) 3 Identification To comply with this standard the lashing points shall be identified by reference to the number of this
24、 standard and the permissible tensile load according to 4.3. EXAMPLE: Identification of a lashing point for a permissible tensile load of e.g. 20 kN: lashing point EN 12640-20. O BSI 02-2001 Page 5 EN 12640:2000 4 Requirements 4.1 Design requirements 4.1.1 Lashing points shall be designed so that th
25、ey transmit the forces they receive into the structural elements of the vehicle. They shall be fixed in the loading platform and in the vertical front end wall. In their position of rest they shall not project above the horizontal level of the loading platform nor beyond the vertical surface of the
26、front end wall into the loading space. NOTE: The recesses in the loading platform required to accommodate the lashing points should be as small as possible. 4.1.2 the conical area determined as follows (see Figure 1): Lashing points shall be designed to accommodate lashing forces applied from any di
27、rection within - angle of inclination 13 from O“ to 60“; - angle of rotation (a) from O“ to 180“ for lashing points with a transverse distance from the side wall and the lashing points 51 50 mm; - angle of rotation (a) from O“ to 360“ for lashing points within a transverse distance from the side wal
28、l and the lashing points 2 50 mrn but S 250 mm. 4.1.3 If the lashing point has a round inside profile then the useable inside diameter shall be 2 40 mm. If it is oval then the clearance in the most unfavourable angle position shall have a width of 2 25 mm and a length of 2 40 mm. The material cross
29、section of the ring or of an oval link shall fit into a circle with a diameter of I 18 mm (see Figure 2). Rings which can move around their complete perimeter when lashed shall not be permitted. 4.1.4 security of the cargo area. The lashing points shall be designed so as not to compromise the splash
30、 protection and the customs 4.2 Number and layout of the lashing points 4.2.1 Lashing points on the floor 4.2-1.1 The number of lashing points shall be determined by the highest result of the following: - length of the loading platform (see 4.2.1.2); - maximum distance between lashing points (see 4.
31、2.1.3); - permissible tensile load (see 4.2.1.4). 4.2.1.2 For vehicles with an effective cargo loading length not exceeding 2 200 mm there shall be at least 4 lashing points, at least 2 on each side. For vehicles with an effective cargo loading length greater than 2 200 mm there shall be at least 6
32、lashing points, at least 3 on each side.

33、e side shall be not more than 1 200 mm. In the area above the rear axle the distance between two adjacent lashing points shall be as close to 1 200 mm as practicable but in any case shall not be more than 1 500 mm; - the distance from front or rear end wall shall not be greater than 500 mm; - the di
34、stance from the side walls of the loading area should be as small as possible and in any case shall not be greater than 250 mm. 4.2.1.4 a) For vehicles with a maximum authorised total mass greater than 12 tonnes, the number of lashing pointsXshall be calculated by use of the formula (I): 1,5 x P 20
35、x= In this case P is the inertial force in kN resulting from the maximum payload. b) for vehicles with a maximum total mass exceeding 7,5 tonnes, but not greater than 12 tonnes, the number of lashing points Xshall be calculated by using the formula (2): 1,5 x P 10 x= c) for vehicles with a maximum t
36、otal mass exceeding 33 tonnes, but not greater than 7,5 tonnes, the number of lashing points Xshall be calculated by using the formula (3): 1,5 x P 8 x= (3) 4.2.2 Lashing points in the front wall The front wall of a vehicle shall be equipped with at least 2 lashing points mounted symmetrically on ei
37、ther side of the vehicle centre line. The lashing points shall be located such that: a) b) the vertical distance of the two lashing points measured from the surface of the loading platform is 1 O00 mm f 200 mm (see Figure 1); the distance measured in transverse direction from the side of the front w
