alleryStart learning →In a radial-travelling cableway, two backstays are required at the stationary tower whenever the angle of travel approaches or exceeds:
A5 degrees
B10 degrees
C20 degrees
D60 degrees
Answer & Solution
Correct answer: C. 20 degrees
1. The stationary tower of a radial cableway must resist a lateral pull as the travelling tower swings around.
2. For a small angle of travel, a single track-cable backstay is sufficient.
3. The unit states that when the angle approaches 20 degrees or more, two backstays are required.
4. The total angle of travel for a radial cableway is usually kept below 40 degrees.
5. The other values are below the two-backstay threshold.
