.4 Air space requirements.

6.1.1.3.4.1 Structures. No passenger tramway installation shall be permitted to operate when a structure
encroaches into the air space of the passenger tramway, defined as the area bounded by vertical planes
commencing at a point thirty-five (35) feet from the intersection of the vertical planes of the ropes or cables
and ground surface.

For purposes of this rule, buildings controlled by the licensee used primarily for maintenance and operation
of the lift and other tramways shall not be considered structures; however, buildings must comply with the
following.

(1) No flammable liquids may be stored in the building outside of a UL listed container or storage
cabinet, unless such flammable liquids are in the original containers and intended for daily
usage. Quantities must be consistent with normal daily use. Class I or II flammable storage
materials shall be limited to 2 gallons in a UL listed container and must be stored either in an
outside storage area or in a UL listed cabinet.



(2) The building must be within the view of the attendant but not impair the

sight line of the lift.

(3) Entrances to all machinery, operators', and attendants' rooms shall be locked

when not in use. Unattended entrances accessible to public, which may be left

open, shall be equipped with barriers to prevent entry.

6.1.1.3.4.2 Cables or ropes. Any cable or rope installed on or near a ropeway that may represent a hazard
to the ropeway shall be monitored to automatically stop the ropeway if the cable or rope fails. Failure
would be defined as per Section 23.1 (g).

EXCEPTION: Track or haul ropes are excluded from this rule.

6.2.3.2 Stop gates.

Automatic stop device(s) shall be installed at each terminal and beyond each unloading area to stop the tow if
actuated by a persons passage.

For actuating device(s) of the suspended type, the suspended portion shall be strong enough to cause release of
the actuating devices in use under the most adverse conditions, and each side shall be detachable and shall
interrupt the operating circuit when detached.

The device shall be in accordance with the following as applicable:

a) Intermediate unloading areas: Required only when passengers are not permitted beyond the intermediate
unloading area;

b) Terminal areas: Installed on the incoming side so that the distance from the stop gate to the first
obstruction is more than 150% of the distance required to stop the empty tow operating at maximum speed.
The stop device shall extend across the tow beneath the incoming rope and insofar as is practical the
outgoing rope;

EXCEPTION: Loading areas where the deflection sheaves or bullwheels are enclosed by guarding, such
that personnel or a passenger cannot be pulled into or have unauthorized access to the deflection
sheaves or bullwheels, are not required to maintain a stop gate at the terminal loading area.

c) Fiber rope tows; Additionally, at unloading areas a device shall encircle the incoming fiber rope.

6.3.1.2.1 Requirement for signs.

(a) The design of any sign as well as its support and the installation procedure of each sign shall be
considered a minor modification if the sign or aggregate of signs on a given tower is greater than three
feet square (nine square feet).
(b) Signs, fasteners, or supporting members shall not interfere with the operation of the tramway.
(c) The design of structural components shall be reviewed to consider the increase in loading caused by any
sign.
(d) Signs shall not interfere with passenger or attendant vision.

6.3.1.3 Operational plan for transportation of recreational equipment. Each licensee shall have an
operational plan that has procedures for transportation of sports equipment and recreational devices by foot
passengers. This plan shall be consistent with the tramway manufacturer's specifications and instructions, if
any.
