Within the general scope defined in Section I of the Introduction, B30.1 applies to general purpose, portable jacks of the following categories:  hand- or power-operated hydraulic jacks, mechanical ratchet jacks, and hand- and power-operated  mechanical screw jacks.

Jacks designed for automotive service, trip-lowered jacks, and those that are an integral part of other equipment are not included in the scope of this standard.  Devices designed for static support rather than lifting are not included.

B30.2-Overhead and Gantry Cranes (Top Running Bridge, Single or Multiple Girder, Top Running Trolley Hoist)

Within the general scope defined in Section I, B30.2 applies to overhead and gantry cranes with a top running bridge of single or multiple girder construction, utilizing a top running trolley, including polar, semigantry, cantilever gantry, wall cranes, and others having the same fundamental characteristics.  This volume includes both power-driven and hand-operated equipment.  These cranes are grouped because they all have top running trolleys and similar travel characteristics.

B30.3-Construction Tower Cranes

Within the general scope as defined in Section I, B30.3 applied to construction tower cranes, powered by electric motors or internal combustion engines, and any variations thereof which retain the same fundamental characteristics.  The scope includes cranes of the above type that adjust operating radius by means of a boom luffing mechanism, or by means of a trolley traversing a horizontal boom, or by means of a combination of the two.  Construction tower cranes may be mounted on fixed or traveling bases.  Additional mounting means may include arrangements that permit the crane to climb in the structure being built, or that permit increasing the tower height as the structure rises and utilizing braces attached to the hoist structure as needed.

The requirements of this Volume are applicable only to cranes when used in lifting work.  Permanently mounted tower cranes (refer to ASME B30.4) and mobile crane tower attachments (refer to ASME B30.5) are not within the scope of this volume.

B30.4-Portal, Tower, and Pedestal Cranes

Within the general scope as defined in Section I, this Volume applies to portal, tower, and pedestal cranes, and any variations thereof which retain the same fundamental characteristics (see exclusions below).  The scope includes cranes of the above type that are powered by internal combustion engines or electric motors, that adjust operating radius by means of a boom, luffing mechanism or by means of a trolley traversing a horizontal boom, that utilize drums and ropes for hoisting loads, and that may be mounted on fixed or traveling bases. 

The requirements of this Volume are applicable only to cranes when used in lifting work.  Construction tower cranes (refer to ASME B30.3), telescopic boom cranes, and knuckleboom cranes are not within the scope of this Volume. 

B30.5-Mobile and Locomotive Cranes

Within the general scope defined in Section I, American National Standard B30.5 applies to crawler cranes, locomotive cranes, wheel-mounted cranes, and any variations thereof which retain the same fundamental characteristics.  The scope includes only cranes of the above types which are basically powered by internal combustion engines or electric motors.  Side boom tractors and cranes designed for railway and automobile wreck clearance, digger derricks, cranes manufactured specifically for, or when used for, energized electrical line service, knuckle boom, trolley boom cranes, and cranes having a maximum rated capacity of one ton or less are excluded. 

Special adaptations to the general types of machines covered by this volume, where applicable, fall under this scope.

Some basic machine types within this scope are convertible for excavating work and other uses not considered to be lifting service.  The requirements of this volume are applicable only to such machines when used as lifting cranes.

B30.7-Base Mounted Drum Hoists

Within the general scope defined in Section I, B30.7 applies to base mounted drum hoists arranged for mounting on a foundation or other supporting structure for lifting or lowering loads, to derrick swingers, and to any variations which retain the same fundamental characteristics.  The scope includes hoists which are powered by internal combustion engines, electric motors, compressed air, or hydraulics, and which utilize drums and rope.  This volume does not apply to overhead hoists, car pullers, barge pullers, truck body hoists, or other hoists or winches used exclusively in horizontal pulling applications.

Provisions of this volume do not encompass all of the safety precautions and safeguards applicable when hoist loads consist wholly, or in part, of personnel.  For personnel handling hoists refer to ANSI A10.4.  When base mounted drum hoists are used as an integral part of other lifting equipment, this Standard may not apply.

B30.8-Floating Cranes and Floating Derricks

Within the general scope defined in Section I of the Introduction, B30.8 applies to cranes and derricks mounted on barges or pontoons.  Floating cranes are convertible for excavation service and other uses that are categorically not considered to be lifting service.  The requirements of this volume are applicable only to machines when used in lifting work (see Figs. 1-5).

B30.9-Slings

Within the general scope defined in Section I, B30.9 applies to slings for lifting purposes, made from alloy steel chain, sewn synthetic webbing, wire rope, metal mesh, and synthetic fiber rope used in conjunction with equipment described in other volumes of the B30 Standard, except as specified in ASME B30.12.  Slings made from materials or constructions other than those detailed in this volume shall be used only in accordance with recommendations of the sling manufacturer.

B30.10-Hooks

Within the general scope defined in Section I, ASME B30.10 applies to all types of hooks shown in Figs. 1 through 21 used in conjunction with equipment described in other volumes of the B30 Standard.  Hooks supporting a load in a direct-pull configuration, with the load carried in the base (bowl/saddle or pin hole- see Figs. 3 and 4) of the hook, are covered in Chapter 10-1.  Hooks that do not support a load in a direct-pull configuration are covered in Chapter 10-2. 

B30.11-Monorails and Underhung Cranes

B30.12-Handling Loads Suspended From Rotorcraft

This Standard applies to the protection of ground personnel working directly with or in the vicinity of rotorcraft.  Within the general scope as defined in Section I, B30.12 applies to the handling of loads suspended from rotorcraft using a cargo sling or powered hoist, or other attaching means, to lift, carry, pull, or tow a jettisonable load outside of the rotorcraft airframe.

B30.13-Storage/Retrieval (S/R) Machines and Associated Equipment

Within the general scope defined in Section I, ASME B30.13 applies to storage/retrieval (S/R) machines and associated equipment, such as aisle transfer cars and aisle equipment (as defined in para. 13-0.2.1), and interfaces with other material handling equipment covered under other standards.  The provisions of this Standard applying to S/R machines shall apply equally to the construction, installation, inspection, testing, maintenance, and operation of aisle transfer cars and any load handling equipment which is part of or attached to S/R machines or aisle transfer cars.

B30.14-Side Boom Tractors

This Standard applies to the manufacture, installation, inspection, testing, maintenance, and operation of side boom tractors used for pipe laying or similar type operations.  In the event that side boom tractors are built or modified for use in other operations, such modifications shall be made by a qualified person and shall comply with requirements set forth in standards applicable to the modified piece of equipment.

This Standard does not apply to side boom tractors having a maximum rated capacity of 1 T or less.
