1. Terms
1.1. Long Splice
1.1.1. jopining the two ends together so that the join is hardly visible
1.2. Counterweight/hydralic cylinders
1.2.1. provide constant tension to the haul rope
1.3. Carriage
1.3.1. a frame that moves back to mantain proper tension on the haul rope as the rope experiences permanent stretch
1.4. Access lift
1.4.1. a lift that moves skiers from the base area uphill to the other lifts
1.4.2. Redundancy
1.4.2.1. to turn on AUX drive when PM is down
2. 8. How does the power supplied by the PM reach the BW?
2.1. Transmission system
2.1.1. Gearbox -> decrease speed, increase torque

4.2. rope tows (bugel), handle tows, platter lifts, T-bars, chair lifts, gondolas, reversible tramways
4.3. Fixed grip VS detachable grip
5. 11. How do lift operators communicate with each other
5.1. voice or signal comm. system
6. 12. What provides power to the PM?
6.1. If electrical motor - >High Voltage circuit
6.2. If diesel engine -> fuel supply/storage capacity
7. 1. The main/central component of a ski lift?
7.1. haul rope
7.2. drive motor/prime mover
8. 2. What supports the haul rope as it moves?
8.1. towers
8.2. sheave and sheave assemblies/line equipment
8.2.1. provide pathway for the rope moving over towers
9. 3. What makes the haul rope move?
9.1. drive bullwheel
9.1.1. provides power to move the haul rope
9.2. return BW
10. 4. What provides power to the drive bullwheel?
10.1. Drive motor provides force to turn the BW
10.2. Drive motor/Prime mover
10.2.1. electric motor OR diesel engine
11. 5. What happens if the prime mover breaks down? (2)
11.1. Evacuation drive - the back-up PM
11.1.1. cannot operate fully loaded at full speed all day
11.2. Auxiliary/Standby drive
