3.1.19 cab An enclosure for the operator and the machine operation controls. 3.1.20 center of gravity Point at which the total mass of a body may be regarded as being concentrated, or about which the parts of a body exactly balance each other. 3.1.21 check valve A mechanical device that normally allows fuid to fow through it in only one direction. 3.1.22 choker hitch A sling confguration with one end of the sling passing under the load and through an end attachment, handle or eye on the other end of the sling. 3.1.23 clutch A means for engagement or disengagement of power. 3.1.24 counterweight Weight used to supplement the weight of the machine in providing stability for lifting working loads and usually attached to the rear of the revolving upper structure. 3.1.25 crane A pedestal-mounted elevating and rotating lift devices for transfer of materials and/or personnel to or from marine vessels, barges, and structures, including the sea, or the seabed. 3.1.26 crane owner The individual, partnership, frm, or corporation who owns the crane. NOTE For the purposes of this standard, a crane owner can be the lease operator (i.e. oil company), drilling or well service contractor, vessel owner, or company that provides temporary crane service. 3.1.27 critical component Any component of the crane assembly devoid of redundancy and/or auxiliary restraining devices whose failure would result in an uncontrolled descent of the load or uncontrolled rotation of the upper structure. 3.1.28 critical rigging component Any component of the rigging equipment devoid of redundancy and/or auxiliary restraining devices whose failure would result in an uncontrolled descent of the load. 3.1.29 designated representative Selected or assigned by the employer or the employer’s representative as being qualifed to perform specifc duties. 3.1.30 emergency load lowering A means of lowering in the event of power failure or control-system failures.
3.1.52 lufng The operation of changing boom angle in a vertical plane (in efect changing the working radius). 3.1.53 lufng cylinder A hydraulic actuator used to change the boom angle. 3.1.54 motion compensation system A system used to control hoist rope tension or relative hook position to counteract vessel motion. 3.1.55 ofboard lift dynamic lift The operation of raising a load (cargo or personnel) of of or landing a load onto a deck where relative motion exists between the load and the crane. 3.1.56 onboard lift static lift The operation of raising a load (cargo or personnel) of of or landing a load onto a deck where no relative motion exists between the cargo and the crane. 3.1.57 overhaul ball The weight on a single part line used to pull the wire rope of the drum with gravitational assistance. 3.1.58 overload A condition where the applied load exceeds the designated rated capacity of the crane or rigging equipment. NOTE Overload does not include shockload, and this standard does not defne shockload. 3.1.59 pawl dog A mechanical device that prevents motion in one or more directions. 3.1.60 pendant line A standing (not running) rope of specifed length with fxed end connections. 3.1.61 person in charge PIC If you are in charge in a particular situation, you are the most senior person and have control over something or someone.
