A projector trolley is a mobile stand designed to hold and move a projector from one location to another. It typically consists of a platform or tray that can securely hold a projector and a set of wheels or casters that allow the trolley to be moved easily. The trolley may also have additional features, such as adjustable height or a built-in power strip for plugging in the projector and other electronic equipment.

Projector trolleys are commonly used in classrooms, conference rooms, and other settings where a projector is needed for presentations or lectures. They provide a convenient and easy way to move the projector around the room and adjust its position and height to accommodate different seating arrangements and presentation styles.
