Whether you’re working on a professional stage show or are a student apprenticing for your high school musical, you’ve likely used rigging. Counterweight rigging, motorized rigging, and dead-hung rigging include components that bring many different aspects of theater to life, whether it’s moving or hanging scenery, lights, or curtains.
The acrobats in Cirque du Soleil can’t “fly” across the stage without rigging. And without rigging to enable quick changes, most productions wouldn’t have the flexibility to depict varied scenery.
Each type of theater rigging has pros and cons and specific uses.
Dead Hung Rigging

This type of rigging is usually used in theaters with low ceilings and includes pipes (battens) or tracks that permanently hang from the ceiling. Dead-hung rigging is not designed to lower equipment to the stage floor. To perform maintenance or change the equipment, a stagehand has to go up to the batten instead of bringing the batten down for adjustments.
Counterweight Rigging
Counterweight rigging systems employ simple physics principles to use balanced weights, pulleys, and ropes to bring many aspects of theater to life. Counterweights – equal amounts of steel weights located backstage – counterbalance the load. Stage workers can easily raise and lower production elements using counterweight rigging systems. When balanced, one tech can move and maintain control over a significant amount of equipment with little effort. However, an error during loading can cause it to be dangerously unbalanced.
Motorized Rigging
While more expensive than counterweighted systems, motorized rigging requires less stage space and less structural steel. Most motorized, automated rigging sets used in theater productions are “dead haul” sets. This means that the motor lifts the entire weight of the equipment, without counterbalancing, which eliminates the safety concerns that come with improperly balanced sets and handling heavy weights.
In addition, with automated rigging, stagehands can physically or digitally lock the controls so an unauthorized operator can’t use them. Motorized rigging systems are excellent when you need to move heavy, multi-element sets quickly and accurately. They allow you to program these movements for precise cues, timing, and consistent performances.
At PORT, we primarily use ETC Prodigy motorized hoists because they are affordable and user-friendly due to their easy-to-read displays and simple controls. Prodigy motorized hoists are lightweight and use compression tube technology, which allows us to connect them to a structure with fewer brackets. That also means you can use them to retrofit spaces that aren’t designed for a stage machinery system.
