ISO 3691-5:2009(E) iv © ISO 2009 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3691-5 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks. This first edition of ISO 3691-5, together with ISO 3691-1, ISO 3691-2, ISO 3691-3, ISO 3691-4, ISO 3691-6, ISO/TS 3691-7 and ISO/TS 3691-8, cancels and replaces ISO 3691:1980, of which it constitutes a technical revision. ISO 3691 consists of the following parts, under the general title Industrial trucks — Safety requirements and verification: ⎯ Part 1: Self-propelled industrial trucks, other than driverless, variable-reach and burden-carrier trucks ⎯ Part 2: Self-propelled variable-reach trucks ⎯ Part 3: Additional requirements for trucks with elevating operator position and trucks specifically designed to travel with elevated loads ⎯ Part 4: Driverless industrial trucks and their systems ⎯ Part 5: Pedestrian-propelled trucks ⎯ Part 6: Burden and personnel carriers ⎯ Part 7: Regional requirements for countries within the European Community [Technical Specification] ⎯ Part 8: Regional requirements for countries outside the European Community [Technical Specification] SIST EN ISO 3691-5:2010

ISO 3691-5:2009(E) © ISO 2009 – All rights reserved v Introduction General This document is a type-C standard as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this document. When requirements of this type-C standard are different from those which are stated in type-A or B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. The ISO 3691 series of standards covers safety requirements and their verification for industrial trucks as defined in ISO 5053. For the purposes of the ISO 3691 series of standards, industrial trucks are wheeled, self-propelled or manually driven vehicles, except for those running on rails. They are operator-controlled and are designed to carry, tow, push, lift, stack or tier in racks. Structure An important step forward in the work on the ISO 3691 series of standards was the agreement to issue a new structure of International Standards for industrial trucks having on one side basic standards for all kinds of trucks (see Foreword) and on the other side independent standards to cover the respective specific functions of industrial trucks, e.g. visibility, noise, vibration, electrical requirements, etc. Assessment of hazards The product needs to be designed in such a way that it is fit for its purpose or function and can be adjusted and maintained without putting persons at risk when used under the conditions foreseen by the manufacturer. In order to properly design a product and to cover all specific safety requirements, the manufacturer will have to identify the hazards that apply to his product and carry out a risk assessment. The manufacturer will then need to design and construct the product taking this assessment into account. The aim of this procedure is to eliminate the risk of accidents throughout the foreseeable lifetime of the machinery, including the phases of assembling and dismantling where risks of accidents could also arise from foreseeable abnormal situations. In selecting the most appropriate methods, the manufacturer will need to apply the following principles, in the order given here: a) eliminate or reduce risks as far as possible by design (inherently safe machinery design and construction); b) take the necessary protective measures in relation to risks that cannot be eliminated by design; c) inform users of any shortcoming of the protective measures adopted; d) indicate whether any particular training is required; e) specify any need to provide personal protection equipment; f) refer to the appropriate user's document for proper operating instructions. SIST EN ISO 3691-5:2010

ISO 3691-5:2009(E) vi © ISO 2009 – All rights reserved Industrial trucks need to be designed to prevent foreseeable misuse wherever possible, if such would engender risk. In other cases, the manufacturer's instructions will need to draw the user's attention to ways shown by experience in which the machinery ought not to be used. This part of ISO 3691 does not repeat all the technical rules which are state-of-the-art and which are applicable to the material used to construct the industrial truck. Reference will also need to be made to ISO 12100. Legislative situation/Vienna Agreement From the very beginning, the task of the working group was to revise ISO 3691:1980 and establish worldwide basic standards to comply with the major legislative regulations in, for example, the EU, Japan, Australia and North America. Every effort was made to develop a globally relevant International Standard. That goal was achieved with most of the issues. For several potential problem areas compromises were needed and will be needed in the future. Where divergent regional requirements remain, these are addressed by ISO/TS 3691-7 and ISO/TS 3691-8. In order to ensure that the revised International Standard will be actively used in the ISO member countries, worldwide, procedures are necessary to replace the existing national standards and technical regulations by the revised International Standard. In the European Community, ISO and the European Committee for Standardization (CEN) agreed on technical co-operation under the Vienna Agreement, with the aim of replacing European Standards (EN) by International Standards. Other countries are asked to make similar agreements to ensure that their national standards and technical regulations are replaced by this International Standard. Only by these actions will there be the guarantee that products in accordance with International Standards can be shipped worldwide freely without any technical barriers.
INTERNATIONAL STANDARD ISO 3691-5:2009(E) © ISO 2009 – All rights reserved 1 Industrial trucks — Safety requirements and verification — Part 5: Pedestrian-propelled trucks 1 Scope This part of ISO 3691 gives safety requirements and the means for their verification for the following types of pedestrian-propelled trucks (hereafter referred to as trucks), equipped with load-handling devices for normal industrial duties, e.g. fork arms and platforms, or integrated attachments for special applications: ⎯ pedestrian-propelled straddle stackers, ⎯ pallet stackers, ⎯ industrial trucks with capacities not exceeding 1 000 kg with manual or electrical battery-powered lifting, ⎯ low-lift pallet trucks with lift height up to 300 mm and rated capacity up to 2 300 kg, ⎯ scissor-lift pallet trucks with lift heights up to 1 000 mm or rated capacity up to 1 000 kg with manual or electrical battery-powered lifting. It is applicable to trucks provided with either manual or electrical battery-powered lifting, operating on smooth, level, hard surfaces. NOTE On-board battery chargers are considered to be part of the truck. Attachments mounted on the load-carrier or on the fork arms which are removable by the user are not considered to be part of the truck. This part of ISO 3691 deals with significant hazards, hazardous situations and events relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). It does not establish the additional requirements for a) climatic conditions, b) operation in severe conditions (e.g. extreme environmental conditions such as freezer applications, high temperatures, corrosive environments, strong magnetic fields), c) electromagnetic compatibility (emission/immunity), d) handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/alkalis, radiating materials, especially brittle loads), e) handling suspended loads which may swing freely handling, f) use on public roads, g) direct contact with foodstuffs, h) operation on gradients or on surfaces other than smooth, level, hard surfaces, SIST EN ISO 3691-5:2010

ISO 3691-5:2009(E) 2 © ISO 2009 – All rights reserved i) lifting systems using belts, j) lifting of persons, k) trucks with overturning moment greater than 40 000 N.m, l) scissor-lift trucks whose lifting is powered by external means (electric, pneumatic), m) roll containers, n) trucks that are intended to be towed by powered vehicles, o) trucks designed for special applications (e.g. hospitals, restaurant trolleys), p) winch-operated trucks, q) mobile lifting tables. Hazards relevant to noise, vibration and visibility are not significant and are not dealt with in this part of ISO 3691. Regional requirements, additional to those given in this part of ISO 3691, are addressed in ISO/TS 3691-7. 2 Normative references The following referenced documents are indispensable for the application of this document.

Additional actual capacity ratings with removable attachments can also be established where permitted by the appropriate stability tests or by calculation using empirical data. 3.5 rated capacity of removable attachments maximum load in kilograms and load centre distance, where applicable, established by the manufacturer of the attachment, which the attachment is capable of handling in normal operating conditions as specified by the manufacturer NOTE For determination, see Annex B. 3.6 rated capacity 〈of a stacker truck〉 maximum load in kilograms given by the manufacturer, based on component strength and truck stability, that the truck can carry, lift and stack to a standard lift height, at a standard load centre in normal position NOTE 1 Where a truck does not lift to the standard lift height, H, it is given a rated capacity at its maximum lift height. For determination, see Annex B. NOTE 2 The rated capacity is used to compare the capacity of different manufacturers' trucks and to provide the break points used in technical standards and statistics. It gives the load that the truck type is capable of transporting or lifting under the above conditions. The safe operating limits for the truck are defined by its actual capacity (see ISO 3691-1). 3.7 normal operating position position in which the operator shall be able to control all functions for load handling as defined by the manufacturer SIST EN ISO 3691-5:2010

Lowering can be by a separate device, e.g. hand-operated lever, foot-operated lever or screw type valve, all of which return to neutral or closed position and stop movement when released. 5.4 Lifting systems 5.4.1 Chain system The truck or mast manufacturer shall have on record a certificate on chains from the chain manufacturer, showing the breaking load of chains. When the lifting mechanism includes a chain or chains, the truck manufacturer shall only use leaf or roller chains. The chain(s) shall provide a minimum safety factor, K1 W 5, when the maximum capacity load is in the transporting position, assuming no friction in the mast structure. K1 is given by Equation (1): 1c()()KLnRw=×+ (1) where K1 is the safety factor of the chain; Lc is the minimum breaking load for a new chain; n is the number of chains; R is the maximum load capacity of the truck; w is the dead weight of lifting mechanism supported by the chains. Pulley diameters shall be in accordance with the chain manufacturer’s instructions. 5.4.2 Wire rope system The truck manufacturer shall select wire ropes that will provide a minimum safety factor of K2 = 6 when the rated capacity is in the transporting position, assuming no friction in the mast structure. K2 is given by Equation (2): 2r()()KLnRw=×+ (2) where K2 is the safety factor of the rope; Lr is the minimum breaking load for new wire rope; n is the number of wire ropes; R is the maximum rated capacity of the truck; w is the dead weight of lifting mechanism. The diameter of wire rope guide pulleys, measured from the bottom of the groove, shall be at least 22 × the diameter of the wire rope. SIST EN ISO 3691-5:2010

ISO 3691-5:2009(E) 14 © ISO 2009 – All rights reserved Splicing of wire ropes, except at the terminal ends, is not allowed. Where more than one wire rope is used, means shall be provided to limit uneven loading in the wire ropes, e.g. by adjustment. 5.4.3 Hydraulic system 5.4.3.1 Limitation of stroke On stacker trucks, the lift assembly shall be fitted with a positive means of preventing over-travelling. In addition, positive means (e.g. mechanical stops) shall be provided to prevent the fork carrier and moving elements of the mast structure from unintentionally disengaging from the upper end of the mast. On pallet and scissor-lift trucks, means shall be provided to limit the stroke of the lifting ram at stroke end. 5.4.3.2 Load supporting The descent of a load equal to the rated capacity caused by an internal leakage in the hydraulic system shall not exceed 25 mm during the first 10 min, under intended operation and with hydraulic fluid at the ambient temperature. 5.4.3.3 Pressure relief valves Except for manually operated lifting trucks, all powered hydraulic systems shall include a device that prevents the pressure in the system from exceeding a preset level, which shall be less than 115 % of the maximum working pressure under the intended operation. The device shall be so designed that it cannot work loose by itself and that a tool or key is required to alter the pressure setting. Manually operated lifting trucks shall be designed in such a way that can be equipped with a pressure-limiting device. 5.4.3.4 Hydraulic circuit All hoses, pipes and connections subject to internal pressure shall be capable of withstanding, without bursting or permanent deformation, a pressure equal to at least three times the operating pressure of the respective hydraulic circuit. On trucks with powered lifting, the hydraulic system shall include a means for appropriate filtering (e.g. a filter or collecting magnet). 5.4.3.5 Lowering speed limitation On stacker trucks, a device shall be incorporated in the lift circuit, which, in the event of a failure of the hydraulic lift cylinder(s), shall restrict the rate of descent of the lifting mechanism with its rated load to 0,6 m/s maximum. On pallet and scissor-lift trucks, the lowering device shall be designed to allow the operator to control the lowering speed, or the lowering speed shall automatically be limited to 0,2 m/s. 5.4.3.6 Failure of energy supply of hydraulic circuit In the case of a fault or interruption of the supply of energy, the design of the hydraulic system shall be such that it does not allow any uncontrolled motion of equipment or attachment. Unintentional descent of the lifting system shall be avoided. 5.4.4 Fork arms and platforms — Stacker trucks only Disengagement of the fork arms from the fork carrier shall only be possible with intentional manual action.

Movements of the attachment and its parts shall be mechanically limited at the extreme positions. 5.4.6.2 Clamping devices Clamping devices shall be so designed that the clamping pressure is automatically sustained for at least 10 min by means of non-return valves or any other effective system when the truck's control mechanisms are in the neutral position, or in the event of a malfunction in the power system of the attachment used for support of the load. Instructions in the event of a malfunction shall be given in accordance with 7.2.3 n). 5.4.6.3 Separate attachment hydraulic system If an attachment has its own separate hydraulic system, this shall comply with the provisions of 5.4.3.4. 5.4.6.4 Attachment hydraulic system connected to truck hydraulic system If an attachment has a hydraulic system that is connected to the truck hydraulic system, then the two systems shall be compatible and the combined system shall comply with the provisions of 5.4.3.4. 5.5 Parking brake Stacker and platform trucks shall be provided with a parking brake that should be sufficient to hold the truck laden to its rated capacity on a gradient of 5 % with a hard, smooth surface. Pallet and scissor-lift trucks shall be designed in such a way that they can be equipped with a parking brake. 5.6 Stability In order to minimize the hazards of longitudinal and lateral tip-over during intended operation, the trucks shall comply with the requirements for the respective tests defined, for example, in ISO 22915-16 without permanent deformation.
