About this file
This document is a technical specification for a free-standing, underhung bridge crane system with a 500-pound capacity. The crane features a 10-foot bridge width, 14-foot runway length, and 10-foot height to trolley saddle, with overall dimensions not exceeding 11.4 feet wide by 14.75 feet long by 11.8 feet high. The structure is steel construction with four support legs requiring 6-inch concrete foundation with anchor bolts. Manual push/pull operation is required for both the bridge and trolley, with stainless steel identification tags mandated on the structure.
The hoist system includes a chain-type electric hoist with 10-foot lift capacity, 16 feet per minute lift speed, and 1-speed operation powered by 460/3/60 volts primary with 120V secondary. Critical safety features include internal overload clutch, electric hoist brake, geared upper/lower limit switches, paddle secondary limit switch, non-resettable hour meter, and zinc-plated load chain. Both hooks require nondestructive testing to ASTM A275 Level 3 examination per NAVFAC P-307. The electrical system includes a remote-mounted NEMA 4 enclosure with 20 feet of festoon wiring, LED status lights, 20% spare wire capacity, and all required fusing and disconnect components. Documentation requirements include OEM load test certification at 125% capacity, certificate of conformance, operations and maintenance manual, hazardous material certificate, loss of power test certification, chain and hook material certificates, and complete as-built wiring diagrams. The system must comply with NAVCRANECEN 11450.2A, NAVFAC P-307, CMAA #70 and #74, ASME B30.16, B30.17, B30 HST-1, MMA MH27.1, and applicable ACI standards.
