Counterweight stage rigging is a system used in theaters to safely and efficiently lift, lower, and balance scenery, curtains, and lighting equipment. It consists of battens, ropes, pulleys, and counterweights that work together to allow stagehands to move heavy objects with relative ease. The system operates by balancing the load on the batten with counterweights on a vertical arbor. Counterweight rigging has many advantages but it must be inspected and maintained regularly. Safety and proper training are critical.
