13、ulic gantry lifting systems; Part 14: Side boom pipelayers.When all parts of BS 7121 have been published, CP 3010 will be withdrawn and BS 5744 will be revised to cover manually operated and light cranes only.Information on the background to the development and use of the BS 7121 series since the in
14、itial publication of BS 7121-1 in 1989 is given in Annex C.The BS 7121 series has been accepted as representing the consensus of practical experience for safety on cranes.Information about this documentThis document is intended to be used in conjunction with other parts of BS 7121 to ensure, so far
15、as is reasonably practicable, that lifting operations are carried out safely.BS 7121-13:2009iv BSI 2009BRITISH STANDARDThe Health and Safety Executive (HSE) commends the use of this British Standard to those who have duties under the Health and Safety at Work etc. Act 1974 5. This standard was drawn
16、 up with the participation of HSE representatives and will be referred to in relevant HSE publications.Use of this documentAs a code of practice, this British Standard takes the form of guidance and recommendations. It should not be quoted as if it were a specification, and particular care should be
17、 taken to ensure that claims of compliance are not misleading.Any user claiming compliance with this British Standard is expected to be able to justify any course of action that deviates from its recommendations.It has been assumed in the preparation of this British Standard that the execution of it
18、s provisions will be entrusted to appropriately qualified and experienced people, for whose use it has been produced.Presentational conventionsThe provisions in this standard are presented in roman (i.e. upright) type. Its recommendations are expressed in sentences in which the principal auxiliary v
19、erb is “should”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible
20、 for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations.BRITISH STANDARD BSI 2009 1BS 7121-13:20091 ScopeThis part of BS 7121 gives recommendations for the safe use of hydraulic gantry lifting systems (HGLS). Subjects covered include safe systems
21、 of work, management, planning, selection, erection and dismantling, inspection, testing, examination, training, operation and maintenance. NOTE 1 This part of BS 7121 has been developed along the lines of BS 7121-1 with significant modifications to incorporate HGLS-specific aspects. The modificatio
22、ns include some information contained in the US Specialized Carriers and Rigging Association (SCb) external cylinder: used on free wheeling jacking units, a cylinder is pinned close to the bottom of the units base at one end and to the track at the other. The cylinder is extended and retracted repea
23、tedly to move the jacking units;c) external drive wheels: one or more motor-driven drive wheels are mounted on the base of the jacking units.3.20 rated capacitymaximum load that the HGLS is designed to lift with the telescopic cylinder(s) at a specific stageNOTE The rated capacity was formerly known
24、 as “safe working load” (SWL).3.21 rated capacity indicatorRCIdevice that warns of the approach to overload and prevents the HGLS from being overloaded NOTE 1 This was previously known as an “automatic safe load indicator (ASLI)” and “overload protection”. For information on ASLIs, see BS 7262.NOTE
25、2 Further information on RCIs is given in BS EN 12077-2.3.22 side shiftinglateral movement of a suspended lifting object, usually accomplished by means of hydraulically propelled skates built into the lifting links or rack and pinion travelling deviceBS 7121-13:20094 BSI 2009BRITISH STANDARD3.23 tra
26、ckassembly consisting of two parallel beams, usually tied together at regular intervals, to guide the wheels of the jacking unitNOTE 1 The beams are either wide flange shapes or fabricated box sections, and are typically fitted with one or more structural elements that guide the jacking units wheels
27、. The beam gauge is equal to the transverse wheel spacing of the jacking unit. Most track is designed in short sections that can be bolted together end to end.NOTE 2 The track members can be designed to carry the jacking unit wheel loads over significant clear spans or to be fully supported by the u
28、nderlying surface, functioning only to provide a smooth, guided surface for the jacking units wheels. Since jacking units are usually operated in pairs, two track assemblies (parallel to one another) are usually required for a lifting operation.4 Management of installation and the lifting operations
29、4.1 Safe system of workA safe system of work should be established and this should be followed for every lifting operation, whether for an individual lift or a group of repetitive operations. The same principles should be applied when the lifting operations are carried out at a temporary site or whe
30、n the HGLS is being used in a permanent fixture for a length of time.The safe system of work should include:a) planning of the operation (by way of the method statement; see 6.3);b) selection, provision and use of a suitable HGLS configuration and associated equipment (may be included in risk assess
31、ment; see 6.2);c) any necessary preparation of the site and erection and dismantling of the HGLS;d) maintenance, examination and, where necessary, testing of the HGLS and equipment;e) the provision of properly trained and competent personnel who have been made aware of their relevant responsibilitie
32、s under the Heath and Safety at Work etc. Act 1974 5, the Management of Health and Safety at Work Act 1992 7 (which is specific to risk assessments and method statements) and Regulation 9 of PUWER 2;f) adequate supervision by properly trained and competent personnel having the necessary authority gi
33、ven by the operator company;g) ensuring that all necessary reports of thorough examination and other documents are available;h) preventing unauthorized movement or use at all times;i) ensuring the safety of persons not involved in the lifting operation.The safe system of work should be communicated
34、to all parties concerned with the lifting operation.BRITISH STANDARD BSI 2009 5BS 7121-13:2009It is essential for the safety of the operation to ensure that all personnel can communicate clearly in the same language.NOTE Attention is drawn to PUWER 2 Regulation 4 and 20 on “Suitability of work equip
35、ment” and “Stability” respectively and LOLER 1 Regulation 4 on “Strength and stability” in relation to the safe system of work.4.2 Control of the lifting operation4.2.1 GeneralIn order to implement the safe system of work effectively, one person should be appointed to have overall control of the lif
36、ting operation to act on behalf of the management of the employing organization. The appointment of the person does not remove any legal responsibility from the management but enables them to use the appointed persons expertise, the better to fulfil their responsibilities. The person appointed may h
37、ave other duties and need not be an employee of the employing organization. The appointed person should have adequate training and experience to enable these duties to be carried out competently. NOTE The appointed person is appointed by either the employing organization or by the HGLS company, depe
38、nding on the contractual circumstances. Occasionally, for the duration of the actual lifting operation, the role of the appointed person may be delegated to the HGLS lift supervisor if this is considered to be more appropriate.4.2.2 Selection and assessment of appointed personWhen selecting an appoi
39、nted person, the employing organization should take into account the variety and complexity of the operation, as well as all the problems that could arise from proximity hazards and environmental courses. The appointed person should be notified formally in writing of their appointment. The appointed
40、 person should be given authority to carry out the duties involved, including consulting others with specialist knowledge and experience, and should be able to delegate duties and tasks for any part of the safe system of work to suitably qualified individuals.The employing organization should review
41、 and assess the performance of the appointed person periodically. The complexity of the installation/lifting operations might entail selection of a more experienced appointed person, as appropriate, or provision of additional training to the existing appointed person.4.2.3 Avoidance of collisionsOn
42、sites where there is a risk of collision between the HGLS and other equipment, the appointed person should plan the sequence of HGLS movements to prevent collisions. Any corresponding instructions from the appointed person to the HGLS lift supervisor should be given directly or via the respective si
43、gnallers. In such circumstances, the signallers should obtain the agreement of the appointed person before carrying out any operation.The positioning of the HGLS and components in the out-of-service condition, as specified by the manufacturers instructions, should be such that no collisions can take
44、 place. This activity should be part of the initial planning process.NOTE To assist in the selection of an appointed person, some examples of lifting operations that require different levels of expertise, training and experience, and that impose different duties on the appointed person, are given in
45、 4.3. Recommendations for installation operations are given in Clause 12 and Clause 13.BS 7121-13:20096 BSI 2009BRITISH STANDARD4.3 Duties of the person appointed to control the lifting operation4.3.1 GeneralThe appointed persons duties should include the following:a) assessing the lifting operation
46、 to provide such planning, selection of HGLS, its configuration and lifting accessories, instruction and supervision (by personnel with the necessary competence, experience and qualifications) as is necessary for the task to be undertaken safely. This might include consultation with other responsibl
47、e bodies, if necessary, and ensuring that, where different organizations are involved, they collaborate as necessary;b) ensuring that adequate inspection/examination and maintenance of the HGLS and associated lifting accessories has been carried out;NOTE 1 For further information, see BS 7121-2.c) e
48、nsuring that there is an effective procedure for reporting defects and incidents and taking any necessary corrective action;d) taking responsibility for the organization and control of the lifting operation.The appointed person should be given the necessary authority for the performance of all these
49、 duties and, in particular, the authority to stop the operation whenever they consider that danger is likely to arise if the operation were to continue.Duties may be delegated to another person (perhaps the HGLS lift supervisor) where considered appropriate.NOTE 2 See 4.2.1 regarding delegation of the role of the appointed person to the HGLS lift supervisor during the actual lift if considered to be more appropriate.The duties of appointed persons for HGLS operations can vary according to the complexity of
