This project involves replacing the hydraulic swivel coupling and trolley hoses on a piggyback crane at Meldahl Locks and Dam. The contractor must supply all labor, equipment, and materials, replace existing brackets with draw chains, and ensure all components are new. After installation, the contractor is required to test the crane and remedy any issues until it is fully operational. Prior to work, the crane must be de-energized and secured, with coordination for Lock-Out Tag-Out procedures. No specific timelines or budget amounts are mentioned in the description.
