ASME B30.14:2015 pdf download.Side Boom Tractors
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 1 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. angled load: any load, other than freely suspended loads, which does not act upon the side boom tractor in a purely vertical manner. approved: accepted as satisfactory by a duly constituted administrative 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. 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 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 ISO 8813-1992). load hoist: a hoist drum and rope reeving system used for lifting and lowering loads. load monitoring and indicating system: any system with the capabilities to measure, advise the operator, and provide appropriate visual and audible warnings for (a) weight of load being lifted (b) the percentage of rated load being lifted load movement: any movement of the load, vertically or horizontally, relative to either the ground or the side boom tractor.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. load overhang, wheel-type tractor: the horizontal distance fromthecenteroftheloadhookmeasured perpendicular to the center line of the tires on the boom side. load, rated: side boom tractor ratings in pounds (kilo- grams) established by the manufacturer in accordance with Section 14-1.1. minimum breaking force: the minimum load at which a new and unused wire rope will break when loaded to destruction in direct tension.
