CAUTIONDO NOT RELY ON THE BOOMANGLE INDICATOR FOR RADIUSACCURACY WHEN LIFTS EXCEED 75PERCENT OF THE RATED CAPACITY.MEASURE TO AVOID THE POSSIBILITYOF ERROR.NOTE: Capacity charts do not apply if themachine has been modified in any way. Ratedcapacity is based on the machine as it was originallymanufactured and equipped.Safe LiftingThe following factors will give you some basicguidelines of what you must know to perform safedaily crane operations:1.2.3.4.5.6.7.8.9.1 0.11.12.13.Determine the weight to be lifted and thecrane required to make the lift safely.Travel the proposed route the crane willfollow to and from the project site, andcomplete the Crane Lift Checklist.Obtain the travel permits if required.Brief operators and riggers on the specifics ofthe lift and travel conditions.Inspect the crane area setup for stability andsafe operating area.Fully extend the outriggers and use themaccording to the manufacturer’s instructions.Check the machine for levelness.Inspect slings, spreader bars, and all otherhardware being used.Select the proper sling with sufficientcapacity rating.Center the sling in the base (bowl) of thehook to avoid hook point loading, and ensurethat the hook block is always placed over thecenter of the load to eliminate shock loadingof the slings or cranes resulting from loadshifts when a lift is made.Make ample safety allowances for unknownfactors.Stand clear of and do not walk undersuspended loads.Boom deflection.deflection. WhenAll crane booms havethe load is lifted off the14.15.ground, the boom will deflect causing theradius to increase.Increased radius maycause overloading of the crane.Clean operating area. Water coolers, excesstools, grease, soda cans, and other un-necessary items should be located outside theoperating area of the crane. Water coolersmust be kept off the crane to prevent peoplefrom walking around the crane when inoperation.Weight on outriggers. On lattice booms,about 60 percent of the load is on theoutriggers close to the load. On hydrauliccranes during near capacity lifts at high boomangles, about 60 percent of the load is onoutriggers away from the load.ATTENTION: SAFE LIFTING IS PARA-MOUNT! PROJECT COMPLETION MUST NOTINTERFERE WITH SAFE CRANE OPERATIONS!TrainingFor deployed units, COMSECOND/COM-THIRDNCBINST 11200.1 series requires biweeklycrane operation and safety meetings be conducted.The meetings review crane operations and includegeneral safety, minimum rigging procedures, craneand rigging responsibilities, and upcoming lifts. TheAlfa company commander, crane test director, cranesupervisor and operators/riggers should attend themeetings.Mishap ReportingIn addition to the requirements outlined inCOMSECOND/COMTHIRDNCBINST 5100.1series, any mishap involving NCF cranes must bereported by message to the COMTHIRDNCB DET,Port Hueneme, California, or the COMSECONDNCBDET, Gulfport, Mississippi.WIRE ROPE SLINGS AND RIGGINGHARDWAREThe use of slings, hooks, spreader bars, shackles,and so forth, for lifting is a vital link in theweight-handling process. An in-depth managementprogram for the maintenance and use of slings isrequired to ensure the entire weight-handlingoperations are performed safely and professionally.The crane crew supervisors are responsible for the3-21
