Current through Register Vol. 54, No. 28, July 13, 2024
No chair lift, gondola lift or skimobile shall be
						operated beyond their design capacity and speed. The following specifics shall
						also apply:
(1)
Single chair
					 lifts.
Lifts shall never be operated beyond their design capacity and
					 speed. Single chair lifts shall not operate for the use of skiers at speeds in
					 excess of 600 feet per minute, nor with chair spacings less than would produce
					 a loading interval of 6 seconds. Outside of the skiing season, or if there is
					 no skiing, such lifts shall operate at lower speed, preferably 350 feet per
					 minute. Such speeds may be increased if a lift is slowed or stopped for loading
					 and unloading. Variations in speed and loading intervals may be approved by the
					 authority having jurisdiction.
(2)
Double chair lifts (including monorail lifts).
Double chairs
					 lifts should not generally be operated for the use of skiers at speeds in
					 excess of 550 feet per minute, nor with chair spacing less than would produce a
					 loading interval of eight seconds. Outside of the skiing season, or if there is
					 no skiing, such lifts shall be operated at a lower speed, preferably 350 feet
					 per minute. These speeds may be increased if a lift is slowed or stopped for
					 loading and unloading. Variations in speed and loading intervals may be
					 approved by the authority having jurisdiction.
(3)
Detachable chair lifts and
					 gondola lifts.
The design capacity of each carrier shall be posted in
					 a conspicuous place on the carrier. Permissible speed of travel is dependent on
					 the facilities provided at the terminals for detaching, attaching,
					 decelerating, and accelerating carriers. The hauling rope is to be continuously
					 moving at a constant speed. Smooth and relatively slow acceleration of the
					 carrier shall be accomplished at full rope speed. Rope speed shall not exceed
					 600 feet per minute, unless approved by the authority having jurisdiction.
					 Means shall be provided to space the carriers at prescribed intervals, never
					 less than those contemplated in the design.
(4)
Skimobiles.
Skimobiles
					 shall not generally be operated at speeds in excess of 550 feet per minute.
					 Loading intervals for single passenger cars shall not be less than four
					 seconds. The speed may be increased if a lift is stopped and started for
					 loading and unloading. Higher speeds and shorter intervals may be approved by
					 the authority having jurisdiction if a proposed scheme is satisfactorily shown
					 to represent a safe operation.
