STATEMENT OF WORK FOR

Crane 148-12 Hoist and Conductor Bar Upgrade

1.0 Scope

The Prototype, Manufacturing, and Test Department (PMTD) is seeking a hoist and conductor bar upgrade on an existing bridge crane in accordance with the requirements listed below. The objective for this project is to replace the obsolete 3-ton Detroit hoist and 3-wire conductor bar of crane 148-12 with a new hoist and 4-wire conductor bar meeting the Navy Crane Centers (NCC) latest requirements. The existing crane is an underhung bridge, and underhung hoist/trolley crane running on 240 volts alternating current with a 5” bridge beam. Current hoist has approximately 17’ of lift. PMTD will retain the current steel runway, bridge and end trucks of crane 148-12. PMTD will also retain the current bridge drive configuration of a single motor driving the bridge wheels through a driveshaft setup. The current hoist is over 40 years old and beyond its useful lifespan. The NCC states the useful lifespan of running hoists is 20 to 30 years. There are new tenants in the space covered by this crane. The new tenants need an upgraded hoist for the precision work required by them.
