Badger Pass Rehabilitate Eagle Lift
Yosemite National Park » Badger Pass Rehabilitate Eagle Lift » Document List
The purpose of this project is to rehabilitate aspects of the Eagle chair lift to insure safe operation during aerial lift transport of visitors and staff. The replacement of components are in-kind which meet current industry standards and will not change the exterior look of Eagle Lift, nor affect the existing landscape. The life expectancy of the Eagle lift components have been met and replacement is required before winter operation of 2008/09.
Scope of Work to include:
Replace 150 carriers, including: chairs, bails, retention bar, and seat pads.
Replace 150 grips on all carriers to stabilize and prevent cracking. Replace the grips, which attach the carrier to the lift cable, with new cast steel grips with greater gripping power and longevity.
Rebuild all seventeen (17) tower sheave assemblies to replace damaged aluminum sheaves, rocker assembly, and axel bushings to insure safe operation. Damage is due to the design of the drive terminal, which causes carriers to constantly wear down the components that allow the carriers to safely attach and transport skiers to the top of the Eagle ski run. New sheave assemblies will retrofit to existing towers, eliminating the need to replace or modify towers.
All vehicles entering Yosemite National Park will adhere to the Division 1 Specifications for spreading noxious weeds. All equipment will be cleaned and checked prior to entering the Park.
Project headquarters will be located at the Badger Pass maintenance facility. Two large staging areas will be located in the main parking areas. A helicopter will be staged in the upper parking lot and utilized for 5 days to remove and replace the sheave assemblies (and prevent meadow disruption).
