SECTION 24-0.1: SCOPE OF B30.24 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 of the B30 Standard. This Volume includes power-operated cranes ofthe above type whose power source is either self-contained or provided exter- nally; single, double,orboxgirderconstruction,utilizing a trolley and a container-handling spreader or other applicable lifting apparatus (cargo hook, cargo beam, magnet, etc.); and rail- or rubber tire-mounted with through-the-legs or between-the-legs operation. Use of the same hardware for purposes other than lifting is excluded from the provisions of this Volume. This Volume does not apply to small industrial truck-type cranes, container-handling toploaders and sideloaders, or mobile straddle-type industrial lifts. SECTION 24-0.2: DEFINITIONS administrative or regulatory authority: governmental agency or, in the absence of governmental jurisdiction, the employer. appointed: assigned specific responsibilities by the employer or the employer’s representative. authorized: appointed by a duly constituted administra- tive or regulatory authority. 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. brake, holding: a friction brake for a hoist that is automati- cally applied and prevents motion when power to the brake is off. brake, parking: a brake for gantry and trolley that may be automatically or manually applied to impede horizontal motion by restraining wheel rotation.
bumper (buffer): a device for reducing the force of impact at the end of permitted travel. cab: a compartment with crane controls for the operator to control the operating functions of a container crane. controller: a device or group of devices that serves to govern, ina predetermined manner, the power delivered directly to the apparatus to which it is connected. controller, spring return: a controller that, when released, will return automatically to a neutral (off) position. crane: a machine for lifting and lowering a load and moving it horizontally, with the hoisting mechanism an integral part of the machine. crane, automatic: a crane that, when activated, operates through a preset cycle or cycles. crane, container: a crane with single or multiple girders carrying a movable or fixed hoisting mechanism used primarily to lift intermodal shipping containers. It uti- lizes a trolley(s) and a container-handling spreader assembly. crane, dockside container: a rail-mounted cantilever gantry crane in which the trolley girder(s) extends transversely beyond the crane runway on one or both sides and is used primarily to lift intermodal shipping containers on and off ships. The crane may have a luffing boom or a shuttle boom (see Fig. 1). crane, service: an overhead crane, jib crane, monorail, or similar crane mounted in the machinery enclosure or other location on a container crane and used for servic- ing the container crane. crane, yard container, rail-mounted: a crane consisting of overhead girders supporting a trolley, mounted on rigid legs, and running on rails (see Fig. 2). crane, yard container, rubber-tired: a crane consisting of overhead girders supporting a trolley, mounted on rigid legs, and running on rubber tires (see Fig. 2). designated person: a person selected or assigned by the employerorthe employer’s representative asbeingcom- petent to perform specific duties.
sheave, equalizer: a sheave used to equalize tension in opposite parts of the rope. Because of its slight move- ment, it is not termed a running sheave. shock load: any condition that causes a momentary increase in the forces in a load-supporting component beyond the weight of the actual load being lifted. side pull: the portion of the hoist pull acting horizontally when the hoist lines are not tensioned vertically. sill beam: horizontal structural members that connect the lower ends of two or more legs of a container-handling crane. slap block: a sacrificial protective device or guard to pro- tect the wire rope or other parts of the crane from rope contact. span: the horizontal distance, center to center, between runway rails or tire centers. spreader: a fixed or telescoping frame attached to the headblock that is used for lifting containers (see Fig. 3). stop, runway or trolley: a device to limit travel. This device normally is attached to a fixed structure and normally does not have energy-absorbing ability. switch: a device for making, breaking, or changing the connections in an electric, hydraulic, or pneumatic circuit.
