ASME B30.26:2015 pdf download.Rigging Hardware
The ASME B30 Standard contains provisions that apply to the construction, installation, operation, inspec- tion, testing, maintenance, and use of cranes and other lifting and material-movement related equipment. For the convenience of the reader, the Standard has been divided into separate volumes. Each volume has been written under the direction of the ASME B30 Standard Committee and has successfully completed a consensus approval process under the general auspices of the American National Standards Institute (ANSI).
abnormal operating conditions: environmental conditions that are unfavorable, harmful, or detrimental to or for the operation of a piece of detachable hardware, such as excessively high or low ambient temperatures, expo- sure to weather, corrosive fumes, dust laden or moisture laden atmospheres, and hazardous locations. adjustable hardware: threaded detachable rigging hard- ware that is adjustable in length, orientation, or position by the user to handle a load. angle ofloading: the acute angle between horizontal and the leg of the rigging, often referred to as the horizontal angle (see Fig. 26-1.9.1-1). NOTE: A stress multiplier produced by the angle of loading is also present when the rigging is used in nonvertical applications. bow, shackle: the curved portion of the shackle body opposite the pin, often referred to as the bail, the body, the dee, or the bowl (see Fig. 26-1.9.4-1). crane scale: see load-indicating device. dead end: the section of wire rope that is not tensioned under load (see Figs. 26-3.1.1-1 and 26-3.1.1-2). design factor: ratio between nominal or minimum break- ing strength and rated load of the rigging hardware.dynamometer: see load-indicating device. ears, shackle: portion of the shackle body that supports the shackle pin (see Fig. 26-1.9.4-1). hardware service normal: service that involves use of loads at or below the rated load. severe: service that involves normal service coupled with abnormal rigging or operating conditions. special: service that involves operation, other than nor- mal or severe, that is approved by a qualified person. hitch, choker: a method of rigging a sling in which the sling is passed around the load, then through one loop eye, end fitting, or other device with the other loop eye or end fitting attached to the load handling device. in-line loading: condition where the load is applied through the centerline of the rigging hardware at the intended bearing points. jaw: a U-shaped, load-bearing connection designed for use with a removable pin (see Fig. 26-2.1.1-1). LID: see load-indicating device. line pull: the tension load in a rope entering a rigging block (see Fig. 26-5.3-1). live end: the section of wire rope that is tensioned under load (see Figs. 26-3.1.1-1 and 26-3.1.1-2). load-indicating device: a device that measures and dis- plays applied load or force. manufacturer: the entity responsible for the physical pro- duction of an item. pin, shackle: a steel bolt made to span the two shackle ears (see Fig. 26-1.9.4-1). primary load fitting: the fitting on a rigging block that carries the highest applied load during use (see Fig. 26-5.3-1). proof load: the specific load applied in performance of the proof tests. proof test: a nondestructive load test made to a specific multiple of the rated load of the rigging hardware.qualified person: a person who, by possession of a recog- nized degree in an applicable field or certificate of pro- fessional standing or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work. rated capacity: see rated load. rated load: the maximum allowable working load estab- lished by the rigging hardware manufacturer. The terms rated capacity and working load limit are commonly used to describe rated load. saddle: the base of a wire rope clip (see Fig. 26-3.1.1-1). shackle: a U-shaped, load-bearing connector designed to be used with a removable pin (see Fig. 26-1.1.1-1).
