It may be fiber, a wirestr<strong>and</strong>, or an independent wire rope.CORING LINE: Wire rope used to operate thecoring tool for taking core samples during thedrilling ofa well.CORROSION: Chemical decomposition byexposure to moisture, acids, alkalies, or otherdestructive agents.CORRUGATED: A term used to describe thegrooves ofa sheave or drum when worn so as toshow the impression ofa wire rope.COUNTERBALANCED TRUCK: A truckequipped with load-engaging means wherein,during normal transporting, all the load is externalto the polygon formed by the wheel contacts (seeFigure 1,.1).COVER WIRES: The outer layer ofwires.CRANE: A machine used for lifting <strong>and</strong> loweringa load vertically <strong>and</strong> moving it horizontally <strong>and</strong>that has a hoisting mechanism as an integral partofit.CRANES, TYPES OF:Automatic Crane: A crane that, whenactivated, operates through a presetcycle or cycles.Cab-Operated Crane: A crane controlledby an operator in a cab located on thebridge or trolley.Cantilever Gantry Crane: A gantry orsemigantry crane in which the bridgegirders or trusses extend transverselybeyond the crane runway on one orbothsides.Floor-Operated Crane: A crane whoseoperation is controlled by use ofapendant in the h<strong>and</strong>s of an operator onthe floor or on an independent platform.Gantry Crane: A crane similar to anoverhead crane, except that the bridgefor carrying the trolley or trolleys isrigidly supported on two or more legsrunning on fixed rails or other runway.Jib Crane: A fixed crane with a verticalrotating member supported at thebottom (also at the top in some types)from which an arm extends to carry thehoist trolley. Jib cranes are mostcommonly mounted on a verticalcolumn, supplied as part ofthe jib crane,or on existing structural members (e.g., awall-mounted jib crane).Overhead Traveling Crane: A crane witha movable bridge carrying a movable orfixed hoisting mechanism <strong>and</strong> travelingon 3D: overhead fixed-runway structure.Power-Operated Crane: A crane whosemechanism is driven by electricity, air,hydraulics, or internal combustion.Pulpit-Operated Crane: A crane operatedfrom a fixed operator station that is notattached to the crane.1-3Chapter 1Terminology <strong>and</strong> Definitions
