(a) Bearing foundations shall be constructed to resist 150% of the maximum design loading.
(b) Guy anchors shall be constructed to resist 150% of the maximum design loads. These loads shall include any variation of loading due to luff ing, or other loads out of the plane of the cableway. Guy ropes shall have a minimum design factor of 3.
(c) Anchorages for track cable tension shall be proportioned to resist the nominal breaking strength of the track cable(s).
(d) If it is necessary to install rope or track cable in contact with the earth or in water, the design factor should be doubled.
19-1.3.2 Rigging and Reeving
a Socketing shall be done in a manner specified by the rope or fitting manufacturer or a qualified person.
(b) No less than two full wraps of rope shall remain on any drum when the lower load block is in the extwmc low position or luffing falls are at their maximum extended length.
(C) The drum end of rope shall be anchored to the drum by an arrangement specified by the cableway or rope manufacturer, the designer. or a qualified person.
(d) Eyes shall be made as recommended by the rope, cableway, or fitting manufacturer or a qualified person. Rope thimbles should be used in the eyes.
(e) Wire rope clips shall be drop-forged steel of the single saddle (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.
(f) Swaged, compressed, wedge-socket, or other type fittings shall be applied as recommended by the rope, cahlewa or fitting manufacturer or a qualified person.
(g) If a load is supported by more than one part of rope, the tension in the parts shall be equalized.
(h) If the track cable(s) is supported by saddles, the saddle radius, rope groove, rope lubrication, and inspection provisions shall conform to the recommendations of the rope, saddle, or cableway manufacturer, the designer, or a qualified person.
