Chain Motor
A Chain Motor is a specialized piece of equipment used in entertainment and set construction to lift and move heavy items like lighting rigs, speakers, or stage elements. Think of it as a sophisticated electric hoist that uses chains instead of ropes or cables. These motors are essential for safely raising and lowering equipment in theaters, concert venues, and film sets. They're similar to regular hoists but are specifically designed for entertainment industry standards and safety requirements. You might also hear them called "stage hoists," "theatrical hoists," or "entertainment rigging motors."
