What is a Motorized Curved Roof Stage Truss System?
A motorized curved roof stage truss system is a ground support aluminum structure that combines a curved roof framework with an integrated electric chain hoist lifting system. It is designed to safely support lighting fixtures, LED screens, line array speakers and stage equipment while providing weather protection for outdoor performances.
Compared with manually lifted truss systems, motorized roof systems improve installation efficiency, reduce labor requirements and offer more precise lifting control.

Engineering Features
Motorized Sleeve Block Towers
The sleeve block system enables the roof to be assembled safely at ground level before being lifted into its final position using synchronized electric motors.
Heavy-Duty Main Beam
The front and side beams use 520×760mm heavy-duty truss, providing excellent rigidity for lighting and suspended equipment.
Curved Roof Geometry
Unlike flat roof systems, the curved profile distributes structural loads more efficiently while creating a more iconic stage appearance.
Independent Speaker Wings
Separate speaker towers reduce additional loading on the main roof while allowing better sound coverage and more flexible system configuration.
Modular Construction
Individual truss sections can be replaced or expanded, making the system adaptable for different stage sizes.
