LIFT, PREENGINEERED PRODUCTION:Repetitive, production-type lifting operation,independent of the nature of the load to be lifted,in which the probability ofdropping, upset, orcollision is reduced to a level acceptable to theresponsible manager by preliminary engineeringevaluation, specialized lifting fixtures, detailedprocedures, operation-specific training, <strong>and</strong>independent review <strong>and</strong> approval ofthe entireprocess.LINE: A rope used for supporting <strong>and</strong> controllinga suspended load.LOAD: The total weight superimposed on theload block or hook.<strong>DOE</strong>-<strong>STD</strong>-I090-<strong>96</strong> (Rev-I)LOAD BLOCK: The assembly ofhook orshackle, swivel, bearing, sheaves, pins, <strong>and</strong> framesuspended by the hoisting ropes.LOAD-BACKREST EXTENSION: A deviceextending vertically from the fork carriage frame.LOAD-BEARING PARTS: Anypartofamaterial-h<strong>and</strong>ling device in which the inducedstress is influenced by the hook load. A primaryload-bearing part is a part the failure of whichcould result in dropping, upset, or uncontrolledmotion ofthe load. Load-bearing parts which, iffailed, would result in no more than stoppage ofthe equipment without causing dropping, upset, orloss ofcontrol ofthe load are not considered to beprimary load-bearing parts.LOAD CENTER (FORKLIFTS): Thehorizontal longitudinal distance from theintersection ofthe horizontal load-carryingsurfaces <strong>and</strong> vertical load-engaging faces oftheforks (or equivalent load-positioning structure) tothe center ofgravity ofthe load.LOW-LIFT TRUCK: A self-loading truckequipped with an elevating mechanism designedto raise the load only sufficiently to permithorizontal movement (see Figure 1-5).MAGNET: An electromagnetic device carried ona cranehook <strong>and</strong> used to pick up loads.MAIN HOIST: The hoist mechanism providedfor lifting the maximum-rated load.MAN TROLLEY: A trolley having an operator'scab attached to it.MARLINE SPIKE: Tapered steel pin used insplicing wire rope.Motorized hanel/rider truck:Figure 1-5. Low-lift trucks.MESSENGER STRAND: Galvanized str<strong>and</strong> orbronze str<strong>and</strong> used to support telephone <strong>and</strong>electrical cables.MODULUS OF ELASTICITY: Mathematicalquantity giving the ratio, within the elastic limit,between a definite range ofunit stress on a wirerope <strong>and</strong> the corresponding elongation.MOUSING: A method ofbridging the throatopening ofa hook to prevent the release ofloadlines <strong>and</strong> slings, under service or slack conditions,by wrapping with soft wire, rope, heavy tape, orsimilar materials.NARROW-AISLE TRUCK: A self-loadingtruck intended primarily for right-angle stacking inaisles narrower than those normally required bycounterbalanced trucks ofthe same capacity (seeFigure 1-6).NONDESTRUCTIVE EXAMINATION (NOE):The development <strong>and</strong> application oftechnicalmethods to examine materials or components, inways that do not impair future usefulness <strong>and</strong>serviceability, in order to detect, locate, measure,<strong>and</strong> evaluate discontinuities, defects, <strong>and</strong> otherimperfections; to assess integrity, properties, <strong>and</strong>composition; <strong>and</strong> to measure geometricalcharacteristics.NONDESTRUCTIVE TESTING (NOT): SeeNONDESTRUCTIVE EXAMINATION.1-7Chapter 1Terminology <strong>and</strong> Definitions
