Construction Project:

Libby Dam Intake Crane Replacement, Libby, MT.

Libby Dam is located on the Kootenai River, a tributary of the Columbia River and located near the town of Libby, Montana. The existing intake crane was designed and fabricated by Fulton Shipyard and installed in 1973. The crane has 3 hoists, each on independently operated trolleys, and performs the multiple functions described below.

• Main Hoist – The 75 ton main hoist is used to deploy the penstock gates for emergency closure. The hoist has a permanently installed, 2 part lifting beam.  The main hoist of the crane is unique in that as the load is lowered in the slot, the lifting beam engages a ledge and splits in half.  This doubles the reeving from 8 to 16 parts and effectively doubles the load capacity.   A total load of 150 tons can be placed on the lifting beam without exceeding the rated load of the crane.
• Auxiliary (Aux) Hoist – The 60 ton auxiliary hoist is used to deploy the sluice gate for emergency closure, place penstock bulkheads, and lift various hatch covers.
• Trash Rack Hoist – The 10 ton trash rack hoist, is rated 10 tons, is used to remove the trash racks and lift various covers

  • Selective Withdrawal Lifting Beam
• Remove existing gantry crane and lifting devices from site.
• Remove existing rail heaters and replace with new rail heaters, including removal and re-installation of asphalt in the rail pockets.
• Remove existing crane electrification system and replace with new crane electrification system.

The existing intake crane provides critical powerhouse functions the loss of which loss of crane use or coverage negatively impacts powerhouse operations. The changeover between the old crane and new crane must be coordinated with Libby Dam to minimize outage.

The Dam Operations will carry on during work under this Contract.

Expected magnitude of construction is between $10 million and $25 million.
