Section 7.465 - Towers

(a) Towers shall be located to conform to the profile of the terrain and be so located that, under the most adverse loading conditions, the towing device is unable to lift any passenger off the snow. Also, under the most adverse conditions, the hauling rope shall be high enough to clear the passenger's head by at least 2 feet. Towers shall also be so arranged that descending empty towing outfits are clear of the snow.

(b) Towers shall be of a height and so located that, if the rope comes off the supporting sheaves of a tower, the towers on either side will support the rope clear of grade by at least 2 feet.

(c) In areas of deep snow, it may be imperative to use variable tower heights. In such cases, changes in tower height shall be made in a manner to avoid overloading or underloading of tower sheave units. This control, when necessary, shall be provided in the manner prescribed in § 7.445(b) (relating to towers).
