Garco-WEMCO JV completed this design-build project to replace two 200-ton gate hoists with movable trolleys and lower blocks at Lucky Peak Dam. These new hoists replaced the original hoists from 1955. The rated capacity requirement for each new hoist was 200 tons; the lifting height requirement was 220 feet; and the lifting speed requirement was 0.9 feet per minute. Our team performed extensive planning and engineering work during the removal and installation phases because of severe space restrictions on the pier of the intake vault and the size of the hatch.

Garco-WEMCO JV was the prime contractor and self-performed 100% of the design, engineering, manufacturing, shop testing, off-site load testing, installation, final commissioning, and testing.
