23、r vehicles, road vehicles and trains. They can also be used to liftcontainers or materials to and from temporary storage. The cranes can beinstalled in a static location, or on rails or wheels such that the crane cantraverse a quay or storage area. They can handle containers, unit loads or bulkmater
24、ials using specialist grabs.1 ScopeThis sub-part of BS 7121-2 gives recommendations for the pre-use checks,in-service inspection, maintenance, thorough examination (in service andfollowing exceptional circumstances) and supplementary testing of cargohandling and container cranes used in ports and in
25、land facilities. This sub-part ofBS 7121-2 is applicable to the following types of cranes: ship to shore or quay cranes; slewing jib cranes, including mobile harbour cranes; level luffing slewing jib cranes; rail mounted gantry cranes; rubber tyred gantry cranes; straddle carrier cranes; scotch derr
26、icks; boat hoists.This sub-part of BS 7121-2 also covers lifting attachments for use in conjunctionwith the cranes, including container spreaders, overheight frames, rotators,grabs, magnets and crane baskets used to access containers on ships.This sub-part of BS 7121-2 is not applicable to permanent
27、ly installed cranes onmarine and other water-borne vessels.This sub-part of BS 7121-2 is not applicable to loader cranes permanentlyinstalled on quays or in other static locations (see BS 7121-2-4).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this

30、1-2-1:2012 apply.4 GeneralRegular pre-use checking, in-service inspection, maintenance and thoroughexamination of cranes are essential if cranes are to function safely and reliably.The nature of these activities can be summarized as follows. Pre-use checks are visual checks which are carried out to
31、ensure that thecrane has not suffered any damage or failure, and is safe to use. In-service inspections and maintenance are carried out to ensure thatcomponents are repaired or replaced before they deteriorate to a point atwhich they would become unsafe. Thorough examinations are carried out at spec
32、ified intervals, afterinstallation on a new site, after major alteration or repair or after theoccurrence of exceptional circumstances which could jeopardize the safetyof the crane. Supplementary testing is carried out in support of thorough examinationand the extent and nature of any testing are sp
33、ecified by the competentperson carrying out the thorough examination.5 Personnel carrying out pre-use checks, in-serviceinspections, maintenance and thoroughexaminationsAttributes, competencies, competency assessment, training plans and trainingrecords of personnel should be in accordance with BS 71
34、21-2-1:2012, Clause 5.6 Pre-use checks and in-service inspections6.1 GeneralPre-use checks and in-service inspection of cranes, together with a system torectify any defects disclosed, are required by the Health and Safety at Work etc.Act 1974 1 Section 2(2)(a), and LOLER 1998 2 Regulation 9(3)(b) to
35、 ensurethat the crane is safe to use and that any deterioration is detected and rectifiedbefore the crane becomes unsafe.Checklists for pre-use checks and in-service inspection should be drawn up foreach individual crane. These should be based on information from themanufacturer, crane usage, findin
36、gs from previous in-service inspections andrecords of maintenance and thorough examination, as applicable. Examples ofchecklists for pre-use checking and in-service inspections of different types ofcranes are given in Annexes A to D. Examples of checklists for pre-use checksand in-service inspection
37、s of crane container top safety frames used to accesscontainers on ships, and container spreaders, are given in Annex E and Annex F,respectively.Pre-use checks and in-service inspections should only be carried out by personnelwho have been adequately trained and assessed as competent to carry out th
38、erequired tasks (see Clause 5). LOLER 1998 2 requires that results of all in-serviceinspections are recorded. It is recommended that the results of all pre-use checksare also recorded.BRITISH STANDARDBS 7121-2-9:20132 The British Standards Institution 2013The crane user should ensure that sufficient
39、 time is allowed for pre-use checksto be carried out before the crane starts work. The user should also ensure thata safe system of work is in place to prevent the person who is carrying out thechecks/inspections from being exposed to danger.6.2 Pre-use checksPre-use checks should be carried out at
40、the start of each period during whichthe crane is to be used. These are to test the functionality of the crane andvisually check for any obvious defects. It is essential that these are carried outfrom a position of safety.Visual checks should normally be made from floor level unless a betterpermanen
41、t vantage point is available.In the event that it does not pass the pre-use check, there should be aprocedure to isolate and lock-off the crane to prevent further use until theproblem has been resolved.6.3 In-service inspectionA regular in-service inspection should be made to identify any defects wh
42、ichmight not be detected by the pre-use checks. In-service inspections should becarried out at intervals which ensure that any deterioration is identified beforethere is a risk of failure of the crane or injury to persons. Further guidance isgiven in HSE document L113 5.It might be convenient to sch
43、edule the inspections concurrently with plannedpreventive maintenance (see 7.2.1).Steel structures suffer from fatigue, a process which can create cracks thatpropagate over time. Cracks can also develop from material or weld defectswhich were undetected during manufacture of the crane. If left unatt
44、ended,cracks can cause serious failure of the crane structure. The in-service inspectionregime should include measures to detect cracks before the safety of the craneis affected. Therefore, in-service inspections should include a structuralinspection of highly stressed areas of the crane.If there ar
45、e any indications of cracking or excessive wear in pins, bearings orstructural components, the crane should be taken out of use and a thoroughexamination should be carried out in accordance with Clause 8, with NDT ifconsidered necessary by the competent person.The period between inspections should b
46、e decided on the basis of the duty ofthe crane and the environmental conditions and might need to vary between1 week and 6 months. The period should be kept under review and adjustedaccording to the results of the inspections.In the event that it does not pass the inspection, there should be a proce
47、dure toisolate and lock-off the crane to prevent further use until the problem has beenresolved.6.4 Reporting of defectsLOLER 1998 2 requires that defects be reported immediately they areidentified. There should be provision for the personnel carrying out the pre-usechecks or in-service inspection(s
48、) to make reports of defects or observationsimmediately they are identified.BRITISH STANDARD BS 7121-2-9:2013 The British Standards Institution 2013 36.5 Records of pre-use checks and in-service inspections6.5.1 GeneralRecords of all pre-use checks and in-service inspections should be kept.6.5.2 Pre
49、-use checksThe record of a pre-use check should include at least the following information: identity of the crane; date and time of inspection; result of the check, i.e. whether or not the crane passed; name and signature of person carrying out the check.This may be kept to a minimum by, for example, completing a single line of apro-forma record.6.5.3 In-service inspectionsThe record of an in-service inspection should include at least the followinginformation: date and time of the i
