Safe working load is the maximum weight that can be safely supported by a rigging point or structure, a limit that varies significantly from venue to venue.
Safe working load, in rigging, is the maximum amount of weight that can be safely hung from a point in a ceiling or structure. The value can vary significantly from venue to venue, depending on the building and the rigging point, so it must be determined for each situation rather than assumed. Respecting the safe working load is fundamental to the safety of suspended equipment, including lighting and audio gear.
Because overloading a rigging point can lead to failure and serious hazard, the safe working load defines a firm limit that must not be exceeded. Rigging is planned so that the combined weight of fixtures, supports, and accessories stays within the rated safe working load of each point.
In commercial production and venue settings, the lighting and AV equipment suspended within these limits depends on power and control wiring to function. While the rigging and its safe working load address mechanical safety, the fixtures it supports rely on dependable cable to deliver power and control.
Because overloading a rigging point can lead to failure and serious hazard, the safe working load defines a firm limit that rigging is planned around, so that the combined weight of fixtures, supports, and accessories stays comfortably within the rated capacity of each point.
At Windy City Wire, the focus on low-voltage power and control cable supports the suspended lighting and AV equipment that rigging holds within its safe working load. Supplying dependable cable helps ensure that fixtures, wherever they are safely rigged, receive the power and control they need.
