Volume B30.14 includes provisions that apply to the construction, installation, operation, inspection, testing, and maintenance of side boom tractors powered by an internal combustion engine used for pipe laying or lift- ing operations, utilizing a lifting boom, drum, wire rope, and/or hydraulic cylinders. The requirements for a side boom tractor that is used for other than lifting operations such as when converted for excavating work, and a side boom tractor with a rated load of one ton or less, are not included in this Volume.
accessory: a secondary part or assembly of parts that contributes to the effectiveness of a machine. administrative or regulatory authority: governmental agency or the employer in the absence of governmental jurisdiction. appointed: assigned specific responsibilities by the employer or the employer’s representative. approved: accepted as satisfactory by a duly constituted administrative or regulatory authority. authorized: approved by a duly constituted administra- tive or regulatory authority. axle: the shaft or spindle with which or about which a wheel rotates. On side boom tractors and wheel-type tractors it refers to an assembly that includes the shaft, housing, and gearing from the shaft to the wheel, sprocket, or equivalent device. boom: a member hinged to the side of the tractor with the outer end supported by a rope system or hydraulic cylinder(s). boom hoist: a hoist drum and rope reeving system used to raise and lower the boom. The rope system may be all live reeving or a combination of live reeving and pendants. The boom may also be raised and lowered by a hydraulic cylinder(s).boom stop: an automatic device used to limit the angle of the boom at the highest position. brake: a device used for retarding or stopping motion by friction or power means. clutch: a friction, electromagnetic, hydraulic, pneumatic, or positive mechanical device for engagement or disen- gagement of power. counterweight: weight used to supplement the weight of the machine in providing stability for lifting loads. designated person: a person selected or assigned by the employerorthe employer’s representative asbeingcom- petent to perform specific duties. drum: the cylindrical members around which ropes are wound. dynamic loading: loads introduced into the machine or its components by forces in motion. load: the external load, in pounds (kilograms) applied to the side boom tractor, including the weight of load- attaching equipment such as load blocks, shackles, and slings. load, rated: side boom tractor ratings in pounds (kilo- grams) established by the manufacturer in accordance with para. 14-1.1. load block, lower: the assembly of hook or shackle, swivel, sheaves, pins, and frame suspended by the hoisting ropes. load block, upper: the assembly of hook or shackle, swivel, sheaves, pins, and frame suspended from the boom point. load capacity, maximum: the capacity for which the tractor is designed (Refer to SAE J743.). load hoist: a hoist drum and rope reeving system used for lifting and lowering loads. load overhang, track-type tractor: the horizontal distance from the center of the load hook to the outer edge of the outer track rail on the boom side (Refer to SAE J743).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. reeving: a rope system in which the rope travels around drums and sheaves. rope: refers to wire rope unless otherwise specified. service, heavy: service that involves operation within the rated load limit that exceeds normal service. service, normal: distributed service that involves opera- tion with randomly distributed loads within the rated load limit, or uniform loads less than 65% of rated load for not more than 25% of the time. service, severe: service that involves normal or heavy ser- vice with abnormal operating conditions. shall: if a provision is of a mandatory nature it is indi- cated by the use of the word shall.
