(a) Effective Date. The effective date ofthis Volume of the B30 Standard shall be 1 yr after its date of issuance. Construction, installation, inspection, testing, mainte- nance, and operation of equipment manufactured and facilities constructed after the effective date of this Volume shall conform to the mandatory requirements of this Volume.
(b) Existing Installations. Equipment manufactured and facilities constructed prior to the effective date of this Volume of the B30 Standard shall be subject to the inspection, testing, maintenance, and operation re- quirements of this Standard after the effective date. Itis notthe intentofthis Volume ofthe B30 Standard to requireretrofittingofexistingequipment. However, when an item is being modified, its performance requirements shall be reviewed relative to the requirements within the current volume. The need to meet the current require- ments shall be evaluated by a qualified person selected by the owner (user). Recommended changes shall be made by the owner (user) within 1 yr.
Volume B30.24 includes provisions that apply to the construction, installation, operation, inspection, testing, and maintenance of container cranes used for lifting purposes, in conjunction with equipment described in other volumes ofthe B30 Standard. This Volume includes power-operated cranes of the above type whose power source is either self-contained or provided externally; single, double, or box girder construction, utilizing a trolley and a container-handling spreader or other appli- cable lifting apparatus (cargo hook, cargo beam, magnet, etc.); and rail- or rubber tire-mounted with through-the- legs or between-the-legs operation. Use ofthe same hard- ware for purposes other than lifting is excluded from the provisions ofthis Volume. This Volume does not apply to small industrial truck-type cranes, container-handling toploaders and sideloaders, or mobile straddle-type industrial lifts.
automatic crane: a crane that, when activated, operates through a preset cycle or cycles. boom: an extension of the trolley runway on dockside container cranes that may be raised (luffing boom) or retracted (shuttle boom) to obtain clearance for gantry travel. brake: a device other than a motor used for retarding or stopping motion by friction or power means. bumper(buffer): a device for reducing the force ofimpact at the end of permitted travel. cab:acompartmentwithcranecontrolsfortheoperatorto control the operating functions of a container crane. container crane: a crane with single or multiple girders carrying a movable or fixed hoisting mechanism used primarilyto liftintermodal shippingcontainers. Itutilizes a trolley(s) and a container-handling spreader assembly. controller: a device or group of devices that serves to govern, in a predetermined manner, the power delivered directly to the apparatus to which it is connected.
crane: a machine for lifting and lowering a load and moving it horizontally, with the hoisting mechanism an integral part of the machine. docksidecontainercrane: arail-mountedcantilevergantry crane in which the trolley girder(s) extends transversely beyond the crane runwayon one or both sides and is used primarilyto liftintermodal shippingcontainers on and off ships.Thecranemayhavealuffingboomorashuttleboom (see Figure 24-0.2-1). drum: a cylindrical member around which wire rope is wound for moving the load, boom, or trolley. emergency stop switch: a manually actuated switch to disconnect power independently ofthe regular operating controls. equalizer sheave: a sheave used to equalize tension in opposite parts ofthe rope. Because ofits slightmovement, it is not termed a running sheave.
