Spanset


Spanset – A round sling made up of nylon strands inside a polyester cover that is capable of hanging heavy weight loads. A spanset is almost identical to a Gac fFex (gac), except that a Gac Flex uses galvanized aircraft cable rather than nylon fiber. Their load capacity is about the same, but a spanset must usually be backed up with a wire safety due to fire code. Since a gac flex is made from wire it requires no safety backup.

Safety


Safety – A wire cable that is used to back-up rigging in case of a failure. A “safety” for a lighting instrument is usually made of a 1/8” stranded wire with a clip on one end and an eyelet on the other. A “safety” for larger items, such as rigging for truss, is often a steel wire rope that is 1/2” in diameter with eyelets on both ends that is usually secured in a loop with a steel shackle.

Chain Motor


Chain Motor – Often referred to as just “a motor”. A type of hoist where a chain is attached to a hang point (usually in the ceiling) and a motor pulls itself, and whatever is attached to it, up the chain. A bag attached to the motor will capture the remaining chain as the motor pulls itself up. A remote called a “pickle” is used to control a single motor. Some remotes, or “motor controllers”, come in various sizes and can control a few or several motor at the same time. Chain motors are rated as to how much total weight (including the weight of the motor and chain) they can lift. The most common ratings are 300 lbs, 1/4 ton (500 lbs), 1/2 ton (1000 lbs) and 1 ton (2000 lbs). Regardless of the motor rating, the amount of weight it lifts cannot exceed the load rating of the hang point (where the chain actually attaches).

Cable Ramp


Cable Ramp – A hard cover for cables used to protect cable from damage and to minimize trip hazards. Cable ramps come in multiple shapes and sizes, but the most common size has five channels for cables and are about three feet in length, about a foot and a half wide, and just under two inches tall.
