Annotation and contents

Applies to the construction, operation, inspection, testing and maintenance of powered, self-erect tower cranes, which adjust operating radius by means of a trolley traversing a jib. These may be horizontal, elevated, articulating, or telescoping, used for vertical lifting and lowering of freely suspended, unguided loads which consist of equipment and materials. Self-erect 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 jobsite to jobsite fully assembled or nearly fully assembled. This volume does not apply to cranes used for non-vertical lifting service or lifting a guided load and truck-mounted material delivery cranes with a tubular boom and trolley traversing the boom. Tower cranes (refer to ASME B30.3) and mobile crane tower attachments (refer to ASME B30.5) are not within the scope of this volume.
