Theliftdirectorshouldhold apre-liftmeetingto discuss the plan and the roles of the personnel involved. (a) At a minimum, the following elements should be reviewed with all load handling activity personnel: (1) overview of the load handling activity (2) LHE, rigging, and other equipment involved in the load handling activity (3) the sequence of events and step-by-step proce- dures for the entire load handling activity (4) safety measures, as required (e.g., Job Safety Analysis action items) (5) load handling activity personnel assignments, addressing (-a) individual responsibilities (e.g., location, time, and task) (-b) work location hazards (e.g., pinch points) (-c) communication methods (-d) personal protective equipment requirements (-e) qualification(s) of assigned personnel (6) any contingency measures as determined in para. 5-2.9 (7) any emergency action plan as determined in para. 5-2.10 (b) Concerns raised during this meeting shall be addressed prior to proceeding with the load handling activity. (c) At the completion of the pre-lift meeting, the lift director should confirm that the attendees understand the plan and their roles and responsibilities during the load handling activity. (d) For repetitive lifts, the lift director should decide the frequency of pre-lift meetings. Pre-lift meetings may not be required prior to each repetition of the load handling activity. 5-4 EXECUTING THE CRITICAL LIFT PLAN 5-4.1 Preparation for the Load Handling Activity The lift director should confirm that all setup and preparation requirements of the plan (see sections 5-2 through 5-3) are in place and all required inspections and tests on the LHE(s) and rigging equipment have been completed.
Immediately prior to performing the load handling activity, the lift director should ensure that either (a) all requirements ofthe plan continue to be metand noconditionsexistthatwouldprecludeimplementationof the plan; or (b) a deviation exists, in which case the load handling activityisnotinitiateduntilthedeviationisaddressedbya qualified person or the liftdirector determines thatcondi- tions are acceptable to allow the activity to begin. 5-4.3 During the Load Handling Activity The lift director should ensure that the load handling activity continues to comply with the plan. (a) If the operation deviates from the plan, the load handling activity should be stopped and evaluated to determine if (1) the load handling activity can resume according to plan. (2) the contingency measures can be implemented per para. 5-2.9. (3) the plan can be readily modified at the site to accommodate an unexpected condition or event. (4) the load handlingactivitycan no longerbe imple- mented as planned, requiring a modified plan to be prepared. In such cases, the load and the LHE shall be secured, if possible, until a new plan can be developed. (b) Changes or modifications to the plan should be communicated to all affected load handling personnel prior to initiating the change. (c) If the load handling activity is stopped for any reason, only the lift director may initiate a restart. 5-5 POST-LIFT REVIEW Afterthecompletionoftheloadhandlingactivity,thelift director should (a) reviewthedevelopment, planning, andexecutionof the load handling activity with the load handling person- nel. Items for review should include, but notbe limited to, the requirements of sections 5-2 through 5-4. (b) identify potential measures to improve future load handling activity. (c) communicate any recommendations identified in (b) to the appropriate personnel for future consideration. (d) for repetitive lifts, decide the frequency ofpost-lift reviews and evaluation of the lift plan. Post-lift reviews may not Crane chartcapacities formobile cranesare the load the crane is rated to support at the boom or jib head as ap- plicable. To evaluate whatpercentage ofthat capacity itis planned to use, it is first necessary to sum the total load applied to the crane at the boom or jib head. Note that in the case of LHE such as tower cranes or overhead traveling cranes, the situation is slightly different, as the capacity is likely to be quoted at the hook block. In all cases follow the instructions and warn- ings of the manufacturer concerning the LHE’s capacity and limitations and adjust your data sheet accordingly. A-2.3 Completing the Example LDS A-2.3.1 Payload and Crane Details Sections. The first two sections,“Payload” and “Crane Details,” are self-expla- natory. Mark nonapplicable fields as “N/A” rather than leavingthem blank(which could be construed as an omis- sion). The “single hoist line pull” is the rated winch line pull. “Parts line used” are the actual parts ofline with which the crane is reeved for the lift (not necessarily the maximum for which itis equipped).“Reeved capacity” is the hoisting capacity as reeved, typically the parts of line times the rated single line pull. This figure is carried below.
