13、th pallets, stillages, hand and powered trucks. BS 4430, Recommendations for the safety of powered industrial trucks Part1:Manufacture. These recommendations form part of a series being developed for industrial trucks, and were prepared under the authority of the Mechanical Engineering Industry Stan
14、dards Committee. Their object is to establish recommended safety practices to be taken into account in the design, manufacture, operation and maintenance of all powered industrial trucks regardless of their travelling speed. This Part2 is specifically concerned with features to be taken into account
15、 in the operation and maintenance of trucks in the interests of preventing damage and deterioration of the equipment, lessening the risk of accidents, and thereby ensuring the safety of personnel. It is, however, equally important to apply the recommendations concerning the design and manufacture of
16、 trucks as described in Part 1. The recommendations are based extensively on the corresponding safety codes prepared by Section IV of the Fderation Europenne de la Manutention (F.E.M.) in whose activities the British Industrial Truck Association plays a leading part, and these codes have been accept
17、ed as a basis for the development of international recommendations on this subject by Technical Committee110 Industrial Trucks, of the International Organization for Standardization(ISO). It will be noted that the supplementary instructions for operators given in2.2 relate only to fork lift trucks.
18、It is intended to supplement these instructions to cover other types of truck as and when international agreement on this subject has been achieved. Similarly, consideration will be given to the preparation of recommendations for the operation and maintenance of industrial tractors used for material
19、s handling. NOTEInformation concerning SI units is given inBS350, “Conversion factors and tables”, and PD5686, “The use of SI units”. To facilitate the change to the metric system, the corresponding imperial units have been given for information purposes. A British Standard does not purport to inclu
20、de all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages
21、i and ii, pages 1 to 5 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS4430-2:1969 BSI 08-1999 1 0 Scope These recommendations apply to the operation and maintena
22、nce of all types of powered industrial trucks regardless of their travelling speed. The term “powered industrial truck” covers all mobile power-driven trucks as described in Section 3 of BS3810-1:1964 1) , with the exclusion of tractors. 1 Operation 1.1 Introduction 1.1.1 The safe operation of power
23、ed industrial trucks should be studied and related to the different conditions existing in the situation and circumstances under which they are required to operate. The information given in this section covers all types of rider-operated trucks. 1.1.2 Each truck should be provided with a booklet giv
24、ing adequate information regarding operating, servicing including lubrication, and maintenance. If a number of trucks are supplied against one order, the number of booklets may be reduced by agreement between the purchaser and the manufacturer. 1.2 Operators 1.2.1 Qualifications. All operators of ri
25、der-operated powered industrial trucks should enjoy good health, vision and hearing, understand traffic regulations, be especially trained for truck driving and be at least18years of age. Operators should receive further training, whenever required to drive a new type of truck. 1.2.2 Identification
26、1.2.2.1 Having been selected and trained, the operator should be designated as an “authorized person”, and should have the right to prevent unauthorized persons (see2.1.1) from using any machine for which he is responsible. 1.2.2.2 The operator should wear a badge or some other visible form of ident
27、ification as an authorized person throughout his working hours. NOTEVarious manufacturers and organizations offer facilities for the initial training of drivers, and it is recommended that all users of industrial trucks should avail themselves of such services. 1.3 Operation of trucks 1.3.1 Overhead
28、 guard. Wherever the operation of the truck exposes the operator to danger from falling objects, the truck should be equipped with an overhead guard. 1.3.2 Load backrest. Fork lift trucks which handle small objects or unbonded loads should be equipped with a vertical load backrest which is of suffic
29、ient height, width, and strength to prevent the load, or part of it, from falling toward the operator when the mast is in a position of maximum backward tilt. Openings in the load backrest should not be larger than the smallest object carried. 1.3.3 Colour of industrial trucks. Trucks should be of a
30、 colour which contrasts with the surroundings. Attention is drawn to BS2929 2) . 1.3.4 Limitation of load. The maximum rated load capacity of the truck, as stated on the identification plate (seeBS4430, BS4430-1 3) ) should not be exceeded. 1.3.5 Exceptional handling. Simultaneous use of2 trucks for
31、 handling heavy or cumbersome loads is a dangerous operation requiring special precautions. It should only be done in exceptional circumstances, by highly experienced operators under the supervision of the person responsible for handling operations. 1.3.6 Operation in hazardous areas. When trucks ar
32、e operated in flammable or explosive areas, they should be specially equipped with the necessary devices to allow them to work in such conditions. Every hazardous area should be marked by special signs warning the operator. 1.3.7 Operation in confined spaces. Trucks with internal combustion engines
33、should not be operated in confined or poorly-ventilated places. 1.3.8 Refuelling and charging stations 1.3.8.1 Fuel handling and storage. Local regulations should be strictly enforced, and should include the following minimum precautions: 1) Powered trucks using highly flammable fuels should be refu
34、elled only at specified locations. 2) The engines of powered industrial trucks should be stopped before refuelling, and should not be restarted until the filler caps on the tank have been replaced and the fuel line itself removed from the machine. 1) BS 3810, “Glossary of terms used in materials han
35、dling” Part 1: “Terms used in connection with pallets, stillages, hand and powered trucks”. 2) BS2929, “Safety colours for use in industry”. 3) BS4430, “Recommendations for the safety of powered industrial trucks” Part 1: “Manufacture”.BS4430-2:1969 2 BSI 08-1999 3) Care should be taken to avoid spi
36、lling fuel over the engine or exhaust system during refuelling operations. If such spillage occurs, the liquid should be wiped away before restarting the engine. 4) Contact should at all times be maintained between the metal outlet of the refuelling hose or the can spout and the fuel tank opening on
37、 the truck, to minimize the possibility of an outbreak of fire due to the discharge of an accumulation of static electricity. 5) Naked flames should never be used to check fuel levels in tanks. 6) Where trucks are powered from L.P.G. cylinders, gaskets and tubing should be suitable for use with that
38、 gas. 7) After connecting up cylinders of L.P.G., a check should be made with soapy water to ensure that all joints are gas tight. 8) L.P.G. cylinders should always be turned off at the valve when a truck is being left for any length of time. 1.3.8.2 Battery charging and changing 1.3.8.2.1 All batte
39、ry charging installations for battery powered trucks should provide facilities for: 1) neutralizing any electrolyte which may be spilled, 2) ensuring adequate fire protection, 3) ensuring proper ventilation, particularly in hot climates where a forced draught system is to be recommended, and 4) prot
40、ecting the charging apparatus itself to minimize the possibility of its being damaged by impact from the trucks which are to be charged. 1.3.8.2.2 Means should be provided for the exchange of batteries with the minimum physical effort. 1.3.8.2.3 All electrical installations in the charging station s
41、hould comply with local regulations. 1.3.8.2.4 All battery changing and charging should be carried out by trained personnel in accordance with battery manufacturers instructions. In the case of automatic charging equipment, this can usually be the authorized operator. 1.3.8.2.5 It is very important
42、that the cell tops be kept dry, and that the battery terminals be kept perfectly clean, lightly smeared with petroleum jelly and correctly screwed down. 1.3.8.2.6 Batteries should be positioned securely on the trucks. 1.3.8.2.7 Naked flames should never be used to check electrolyte levels in batteri
43、es, and smoking should be prohibited during this operation. 1.3.8.2.8 The battery of an electric truck should, never be replaced by another battery having a different weight or dimensions without referring to the truck manufacturer who will indicate the necessary steps to be taken in order to ensure
44、 that the stability of the truck is maintained. 1.3.9 Slinging of trucks. Trucks should only be slung at the points indicated by the manufacturer. 1.4 Operating conditions 1.4.1 State of ground surfaces. Floors and roads should be of adequate load-bearing capacity, sufficiently hard, and as smooth a
45、nd level as possible. Approaches to gutters, railway crossings, etc., should be hard and smooth, and fitted with ramps where necessary, to prevent displacement of loads. Roads designed to take trucks should be free of all obstacles and conspicuously defined with paint (or equivalent process). 1.4.2
46、Dimensions of aisles. Aisles for trucks should be arranged to facilitate turning. Inclines and steep ramps, narrow passages and low ceilings, should be avoided. Aisles should be of sufficient width to allow for satisfactory operation of all the types of trucks to be used, account being taken of the
47、nature and dimensions of the loads to be carried. 1.4.3 Headroom. Doorways and structures over aisles sufficiently low to form an obstacle to industrial trucks should have warning notices ahead of the obstacle, and should be outlined by a band of conspicuous colour, as shown in BS2929 4) . 1.4.4 War
48、ning signs. Hazardous spots should be indicated by signs similar to those used on highways. 1.4.5 Gradients. It is recommended that gradients do not exceed10%. These should provide for a smooth gradual change at top and bottom to prevent shocks to the load or fouling of the underside of the truck. T
49、urning trucks on gradients or driving trucks across gradients should be avoided wherever possible. The use of laden trucks should be prohibited on gradients if the brakes will not stop the truck within a safe distance. 4) BS2929, “Safety colours for use in industry”.BS4430-2:1969 BSI 08-1999 3 1.4.6 Bridge plates. Bridge plates should have an adequate safety margin to support loaded trucks. The maximum permissible load should be shown on the plates, clearly and permanently. 1.4.6.1 Bridge plates should be secured to prevent accidental movement. 1.4.6.2
