17、3:2014EN 16203:2014 (E) 4 Introduction This European Standard is a type C standard as stated in EN ISO 12100:2010. This standard has been prepared to be a harmonized standard to provide one means of conforming to the essential safety requirements of the Machinery Directive and associated EFTA regula

18、tions. The extent to which hazards are covered is indicated in the scope of this standard. NOTE 1 The requirement for a dynamic test is intended to be included in EN 16307-1, Industrial trucks Safety requirements and verification Part 1: Supplementary requirements for self-propelled industrial truck

19、s, other than driverless trucks, variable -reach trucks and burden-carrier trucks. The purpose of this standard is to provide a procedure for verifying the lateral stability of the truck while travelling. The procedure can be used as a type test as well as an individual test. The truck is designed s

20、o that when travelling, laden or unladen, it will remain stable while being operated on smooth level ground under conditions of use defined by the manufacturer, e.g. by controlling travelling velocity, steering rate of change, acceleration and deceleration, position of load handling device. To reduc

21、e the risk of lateral instability for lifting, furthermore it is proposed to indicate this misuse of driving with elevated load by signals or by reduction of the driving velocity when exceeding a certain lift height. This requirement is intended to be included in the respective standard in its next

22、revision. NOTE 2 This standard is not intended to completely eliminate the possibility of a lateral tip over in all working conditions, i.e. it is possible to exceed the lateral stability limits if slightly uneven or sloping surfaces combine with unsafe driving practices. BS EN 16203:2014EN 16203:20

23、14 (E) 5 1 Scope This European Standard specifies dynamic tests for the verification of lateral stability for counterbalanced lift trucks according to EN ISO 3691-1 that have a centre control, sit down, non-elevating operator, with a rated capacity up to and including 5 000 kg when travelling on smo

24、oth level ground with the forks in travelling position. The standard is not applicable for Rough Terrain forklift trucks. NOTE 1 Experience shows that counterbalanced lift trucks with a rated capacity over 5 000 kg are not significantly affected by lateral instability. The requirements are specific

25、to the various drive systems (e.g. Electric-/Internal-Combustion-Engine trucks), taking account of their varying influence on dynamic stability performance. This European Standard does not cover the risk of a lateral tip over associated with driving backwards. NOTE 2 Research has shown that driving

26、backwards in typical working operations, such as unloading of a lorry, does not cause lateral instability. For this reason, only driving forward needs to be tested. Risks due to falling off a loading dock or turning on a ramp are not covered by this European Standard. Risks due to lifting or manoeuv

27、ring operations are covered by the respective stability tests. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the

28、 latest edition of the referenced document (including any amendments) applies. EN ISO 3691-1:2012, Industrial trucks - Safety requirements and verification - Part 1: Self-propelled industrial trucks, other than driverless trucks, variable-reach trucks and burden-carrier trucks (ISO 3691-1:2011) ISO

30、tions Note 1 to entry: If the truck velocity is automatically reduced in certain load device positions (i.e. lift height dependent), this reduced velocity is the maximum velocity for that load condition. 3.2 test velocity velocity greater than 90 % of the maximum velocity BS EN 16203:2014EN 16203:20

31、14 (E) 6 4 Test equipment 4.1 Test area The test area shall be a flat and smooth area with a hard, clean and dry surface made of concrete, asphalt or equivalent. The lanes shall have no more than 2 % slope in any direction of travel and the slip friction coefficient of tyres and surface shall be bet

32、ween 6.0= and 8.0= . The slip friction coefficient can be measured as described in Annex B. The slip friction coefficient may change by environmental influences (temperature, moisture, intermediary medium) as well as by type and wear condition of tyres and road surface. Therefore, a friction measure

33、ment shall be carried out before each test series. The area shall be clear of all loose chippings, sand or anything similar. The test track shall consist of two perpendicular crossing lanes (see Figure 1). The lanes are defined by lines 1 to 8, of which at least lines 2, 3, 4, 5 and 8 shall be conti

34、nuously marked on the ground (e.g. by painted lines, adhesive tape, non-fixed wooden lathes, ropes or chains, etc.). The defining lines shall be marked so they are clearly visible to the operator whilst driving. Whilst the preferred test track will have a shape similar to those of Figure 1, alternat

35、ive test tracks in accordance with Annex A may be used.

Additional appropriate measures sha

39、ll be used to verify that the accelerator pedal is fully pressed while driving between line 1 and line 6 or line 7 (e.g. contact sensor under the accelerator pedal). Furthermore, appropriate sensors, a video camera or human observers are necessary to detect whether the test is valid. 4.3 Protective

40、equipment and precautions To enable tests with minimal risk to the driver the truck shall be fitted with: a) an operator restraint system, preferably a seat belt, which maintains the driver safety; b) outrigger type stabilizers as protective equipment to prevent the truck tip-over: 1) The test truck

41、 shall be equipped with stabilizers on both sides of the truck. 2) The clearance between the stabilizers and the ground shall be such that tip-over of the vehicle is prevented but a rear wheel lift-off is still possible. For trucks with articulating steer axles, full articulation shall be possible b

42、efore the stabilizers make contact with the ground. BS EN 16203:2014EN 16203:2014 (E) 8 3) The stabilizers shall be fixed rigidly and securely to the truck. 4) The total mass of the stabilizers shall be less than 10 % of the weight of the unladen truck. 5) The position of the centre of gravity of th

43、e truck shall not be lowered by attaching the stabilizers. 4.4 Test Load Test shall be carried out with the unladen truck as defined in Clause 5. 5 Test truck The truck to be tested shall be in a safe and functional state. All equipment attached shall be in accordance to the specification of the man

44、ufacturer of the truck. If the test is to be performed on a sample that is representative for a range of trucks, the test shall be carried out on the truck with the most disadvantageous stability values. The fuel tanks of internal combustion engine trucks shall be filled if stability is thereby decr

45、eased. All other tanks shall be filled to their correct operating levels, as applicable. The test truck shall be fitted with new tyres (max. 10 % of tread wear) which shall comply with the specifications of the manufacturer of the truck. Pneumatic tyres shall be inflated to their correct pressure sp

46、ecified by the truck manufacturer. 6 Requirements 6.1 General Dynamic lateral stability The dynamic lateral stability shall be verified by testing as defined in this standard. Simulation as calculations, computer modelling or other equivalent simulating methods may be used, provided that the results

47、 are validated by testing as defined in this standard. 6.2 Test Criteria The truck shall run the test according to Clause 7 for the measurement w2. w2is defined by the formula: 232bww += m (1) The measurement w3, for electric driven trucks given in Figure 3 and for IC-driven trucks given in Figure 4

48、, depends on the maximum velocity and the truck width b is shown in Figure 2. EXAMPLE To determine the width of the exit lane, w2, for an electric driven truck with a maximum velocity of 10 km/h: Find the maximum truck velocity along the x-axis and record the value of w3on the y-axis where a vertica

49、l line from the maximum truck velocity crosses the graph curve: in this case w3= 5 m. Substitute w3in Formula (1) in 6.2 to determine w2for this specific truck. This requirement is fulfilled if three successful attempts are obtained within a maximum number of twenty attempts. An attempt is successful in the case that it is: a) a valid attempt; BS EN 16203:2014EN 16203:2014 (E) 9 and b) the subsequent relevant criteria are fulfilled: 1) for a three wheel truck with 1 wheel on the rear axle this rear wheel has contact to the ground; or 2)
