TJ-573-01 Cranes Deck and Boom O M_weight chart.pdf

This is an installation drawing specification for a maritime crane system, identified as document TG811-AT-MMC-010. The document presents detailed technical specifications for a main hoist system with static rated load and safe working load capacities across various boom heights and configurations.

The drawing illustrates an elevation view of a ship-mounted crane installation with key components including a main hoist mechanism, swing drive, winch cylinder, extension cylinder, lift cylinder, and pedestal mounted on a ship deck. Two capacity tables are provided: the Main Hoist - Static Rated Load table lists capacities ranging from 5 feet to 50 feet boom reach, with maximum static loads varying from 16,780 lbs to 7,190 lbs depending on boom extension and angle; the Main Hoist - Safe Working Load at Sea table provides corresponding safe working loads for the same configurations, accounting for dynamic maritime conditions. Both tables include measurements for boom reach in feet, angle in degrees, and capacity in pounds, with distinctions between extended and retracted boom positions. The document specifies that the swing drive and winch are omitted for clarity in the diagram, and notes that safe working load calculations include the weight of the hook, rigging, and wide rope (begun hook tip), among other factors. This represents Sheet 1 of 10 in a comprehensive installation drawing set.
