ASME B30.14 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 p-ns’ered by an internal combustion engine used for pipe laying or lifting 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 I ton or less, are not included in this Volume.
(15) SECTiON 14-0.2: DEFiNITIONS
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 shalt, housing, and gearing from the shaft to the wheel, sprocket, or equivalent device.
a member hinged to the side of the tractor with the outer end supported by a rope system or hydraulic cylinder(s).
boarri 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).
(a) The hoist rope shall be of a construction recommended for side boom tractor service. Rotation resistant rope shall not be used.
(b) End terminations shall be done in the manner specified by the manufacturer of side boom tractor, the wire rope, or the fitting.
(C) If a load is supported by more than one part of rope, the tension in the parts shall be equalized.
(d) Wherever exposed to temperatures at which fiber cores would be damaged, rope having an independent wire-rope or wire-stand core, or other temperature- damage resistant core shall be used.
14-1.6.3 Reeving Accessories
(a) Eye splices shall be made in accordance with manufacturer’s recommendations and rope thimbles shall be used in the eye splices.
(b) Wire rope clips shall be drop-forged steel of the single saddle-type (U-bolt) or double saddle-type clip. Malleable cast iron clips shall not be used. For spacing. number of clips, and torque values, refer to the clip manufacturer’s recommendation. Wire rope clips attached with U-bolts shall have the U-bolt Over the dead end of the rope and the live rope resting in the clip saddle. Clips shall be tightened evenly to the recommended torque. After the initial load is applied to the rope, the clip nuts shall be retightened to the recommended torque to compensate for any decrease in rope diameter caused by the load. Rope clip nuts should be retightened periodically to compensate for any further decrease in rope diameter during usage.
(c) Swaged, poured, compressed, or wedge socket fittings shall be applied as recommended by the rope, side boom tractor, or fitting manufacturer.
14-1.6.4 Sheaves
(a) Sheave grooves shall be free from surface defects that could cause rope damage. The cross-sectional radius at the bottom of the groove should be such as to form a close-fitting saddle for the size of rope used. The sides of the groove shall be tapered outward and rounded at the rim to facilitate entrance of the rope into the groove. Flange rims shall run true about the axis of rotation.
(b) Sheaves carrying ropes that can be momentarily unloaded shall he provided with close-fittings guards or other suitable devices to guide the rope back into the groove when the load is applied again.
