• Passage of men and materials in the rope slope will be assisted by a hoist. Rail (85 <br />lb /yd) will be installed in the rope slope (west slope) with surface turnouts as shown <br />on Map 11 Sheet 1 East Portal Roads, Slope Track and Cut Areas. A typical <br />slope rail section is included on Map 11 Sheet 1 East Portal Roads, Slope Track <br />and Cut Areas. The 85 lb ASCE rail spacing is planned at 42 inches. The rail will <br />be set on iron -clad steel ties (3" x 8" x 72 ") bedded in ballast/crushed rock. <br />The hoist sheave and the hoist are located as shown on Map 11 sheet 3 East Portal <br />Facilities. The main components of the single drum mine hoist are a 300 HP DC <br />motor, 60:1 gear reducer, hoist drum assembly, and brakes. The hoist will be placed <br />on new foundation housed within a 20 ft by 40 ft metal building. The tower is <br />designed to support a 7 ft sheave wheel to deflect the 1 V2" wire rope down the 17 <br />degree slope. The details of the foundations are included in Exhibit 28 — Bond <br />Calculations. <br />• <br />TR -54 Page 2.05 -7a Revised 11 /l /10 <br />
