ASME B30.29:2018 pdf free download.Self-Erecting Tower Cranes.
Volume 830.29 includes provisions that apply to the construction, operation, rnspectlon. testing, and maintenance of powered self-erecting tower cranes that adlust operating radius by means of a trolley traversing a jib. These may be horizontal, elevated, articulating, or telescoping, and used for vertical lifting and lowering of freely suspended, unguided loads that consist of equipment and materials.
Self-erecting tower cranes have vertical or nearly vertical masts that are bottom slewing and mounted on fixed, traveling, or mobile bases. The cranes are capable of moving or being moved from job site to job site fully assembled or nearly fully assembled.
This Volume does not apply to cranes used for nonvertical lifting service or lifting a guided load, or to truck- mounted material delivery cranes with a tubular boom and trolley traversing the boom, Tower cranes (refer to ASME 830.3) and mobile crane tower attachments (refer to ASME 830.5) are not within the scope of this Volume.

accessory: a secondary part or assembly of parts that contributes to the overall function and usefulness of a machine.
administrative or regulatory authority: govern mental agency, or the employer in the absence of governmental jurisdiction.
axis of rotation: the vertical line about which a crane swings.
axle: the shaft or spindle with which or about which a wheel rotates. On wheel-mounted cranes, it refers to a type of axle assembly including housings, gearing. differential bearings, and mounting appurtenances.
balanced: the condition of the superstructure of a self- erecting crane necessary for telescoping the mast; the load is positioned at that radius that causes the vertical.
