Ski Lift Installation Regulations
Ski lifts are regulated under the ANSI B77.1-2017 standards. Prior to being opened to the public, new or relocated aerial lifts must undergo and pass the following two test requirements
Reference document: https://catsr.vse.gmu.edu/SYST490/495_2018_SkiLift/SkiLift_Final_Report.pdf - Page 9 Section 1.4
Prior to being opened to the public, new or relocated aerial lifts must undergo and pass the following two test requirements:
1. qualified personnel shall thoroughly test and verify compliance with the plans and specifications of the designer/manufacturer.q
2. designers or manufacturers shall propose and submit an acceptance test procedure [15].
Following the initial installation phase, as stated in the ANSI B77 standards, ski lift owners are subject to meet the following conditions for their ski lifts prior to being opened to the public:
a. tightness of all structural connections
b. lubrication of all moving parts
c. alignment and clearances of all open gearing
d. installation and alignment of all drive system components
e. position and freedom of movement of counterweights or other tension systems and carriages
f. haul rope alignment at entrance to bull wheels
g. operation of all electrical components, including circuit protection and grounding
h. adjustment of brakes to design deceleration rates and baseline brake torque testing
i. minimum clearances for carriers, track cable(s), and haul rope sags under the most adverse static loadings
j. proper alignment of track cable saddles and haul rope sheave units
k. proper track cable to saddle angles and unhindered inline motion of track cable in saddles as applicable
l. actual testing of evacuation equipment and procedures at the most difficult location
m. proper location of towers and terminals in accordance with the plans and specifications. Terminal and tower rope/cable working points shall be documented by an “as built” survey, and any variation from the design drawings shall be noted and approved by the engineer responsible for design
n. slip testing of carriage haul rope clamps, if used, for required force (see 2.1.4.4.2.2(h))
State inspection regulations reference ANSI B77 standards, and these conditions serve as the baseline for continuing ski lift inspections after the installation of the lift. ANSI B77 standards define that inspection schedules must be developed to ensure that “foundations and structural, mechanical, and electrical components, shall be inspected regularly and kept in a state of good repair” [15]. However, they 10 seldom define what a state of good repair is. Inspection methods are also lightly defined in term
