Excerpt
Excerpt: General Information. 772-1.1. Purpose. This chapter provides information to personnel of the United States Navy charged with the safe and reliable operation, maintenance and testing of installed cargo and weapons elevator equipment. Related elevator equipment and systems manuals, Ship’s Information Books (SIBs), Elevator Military Specifications (MIL-SPECs), General Specifications for Ships of the United States Navy (GENSPECs), OPNAV Instructions, Ordnance Publications (OPs), Technical Manuals (TMs), appropriate Maintenance Requirement Cards (MRCs), together with this NSTM, will mesh system components with their appropriate test instrumentation, gauges, controls, tools, spare and repair parts, equipage information, and drawings. This NSTM is not intended to be a compendium of total elevator system design and engineering information, nor an all encompassing document covering all configurations of shipboard installed equipment. It provides guidance and information that personnel must have to obtain optimum elevator performance throughout its life cycle.
