Rigging (material handling) in the context of "Block and tackle"

Rigging is both a noun (equipment), and verb, (the action of designing and installing the equipment), in preparation to move objects. A team of riggers design and install the equipment needed to position (raise, roll, slide or lift) objects such as heavy machinery, structural components, building materials, or large-scale fixtures with a crane, hoist or block and tackle.

Rigging comes from rig, to set up or prepare. Rigging is equipment such as wire rope, turnbuckles, clevis, jacks used with cranes and other lifting equipment in material handling and structure relocation. Rigging systems commonly include shackles, master links and slings, and lifting bags (for underwater lifting).
