Project Description

The work is to demolish the existing two-winch tow haulage system at Murray Lock and provide a complete operational replacement system (with select components reused or refurbished). The replacement system uses a single loop of 3/4" wire rope from the single rope-on rope-off 50 horsepower electric winch to the kevel bitt and back to the winch with a pulling force of ~10,000 lb. at the kevel bitt (approximately 11,900 lb. at the winch drum) and a maximum kevel bitt speed of approximately 117 feet per minute. The winch operates via an Adjustable Speed Drive (ASD) located in the lock house across the chamber from the winch; the work includes replacing all power, controls, and appurtenant electrical components. The wire rope between the winch and kevel bitt is routed via 10 mounted sheaves approximately 18 inches in pitch diameter (5 sheaves on both parallel rope sections) with a portion of the rope routing via a ~1 foot deep concrete trench to be cut in the lock wall concrete as part of the work. Following installation of the replacement system, training of Government personnel and field testing shall be provided including operational testing using a loaded barge or equivalent alternative and system functional testing.

The work includes demolition of two existing tow haulage electrohydraulic winch units, two existing A-frame crossover sheave towers, existing wire rope, and all power and controls to the above mentioned equipment. Proposed work includes providing one electrically driven tow haulage winch, ASD, all electrical power, sheave assemblies, wire rope, controls, and incidental related work. Work also includes concrete saw cutting and concrete removal for the trench and the refurbishment of the existing kevel bitt.

Existing Items to be demolished:

1. Downstream hydraulic winch
2. Upstream hydraulic winch
3. Downstream sheave A-frame tower
4. Upstream sheave A-frame tower
5. Upstream gate shelter control components
6. Downstream gate shelter control components
7. Electrical service (conductors and circuit breakers) to upstream and downstream winch
8. Monolith concrete for cable trench
9. Downstream winch weather shelter
10. Existing wire rope
11. Downstream intermediate handrails

Items to be provided:

1. Single drum, electric driven, ASD-operated rope-on rope-off winch at upstream location       
2. Sheave assemblies at wire rope trench, lock wall (multiple locations)
3. Close-fitting sheave rope groove guard pin assemblies
4. Sheave Safety Cage Assemblies
5. Wire Rope and End Terminations
6. Electrical service to winch assembly (conductors and circuit breakers)
7. Grating for wire rope trench
8. Weather shelter for winch drum assembly (if not fully reused)
9. Upstream intermediate handrails (if not fully reused)
10. Jib crane for winch motor removal during future flood operations
11. Upstream gate shelter control components
12. Downstream gate shelter control components

  

Item(s) to be re-used

1. Kevel rail
2. Upstream winch weather shelter
3. Upstream intermediate handrails
    

Item(s) to be refurbished

1. Kevel Bitt
