NOTE: The following description is a GENERAL Overview of this career and not a description of a particular job posting.
Shipyard Riggers assemble and install rigging gear such as cables, ropes, pulleys and winches to lift, lower, move or position machinery, structural steel and other heavy objects. They use weight handling equipment such as fork trucks, cranes, wire ropes (all types), end fittings, slings, winches, chain falls, boat slings, boat davits, and horizontal and verticals pad-eyes. The experienced Rigger will normally be able to perform all the following tasks: examine objects to be moved, estimate their size, shape and weight and decide on the type of equipment necessary; erect a temporary jib or derrick if required, and install cables, pulleys and other tackle; choose or make slinging equipment and attach it to the load; erect cranes and mobile crane booms, increase the height of tower cranes by bolting component parts in place, and rigging cables; splice ropes and cables to make slings and tackle; erect structural steel for buildings under construction; erect panels used on facades; and inspect, maintain and repair equipment of trade.
A career as a rigger typically requires a high school diploma, and anywhere from a few months to one year of experience working with the required tools and skills, particularly in a marine environment. A recognized apprenticeship program may be associated with these occupations.
Some previous work-related skill, knowledge, or experience is usually required.
