Teatro Regio
Stage upgrade works
Projects /
Turin, Italy – 2022
In the heart of the historic Teatro Regio, Decima carried out extensive work on the entire stage machinery, split into two consecutive phases to ensure the full continuity of the theatrical season.
The project covered both the complete modernisation of existing components and the installation of new motorised lifting, control and stage movement systems, with a constant focus on safety, reliability and operational precision.

Upper stage machinery
The upper stage machinery includes fly system and electric variable speed 6-rope scale hoists, for lifting and moving scenery, backdrops, lighting trusses, an intermediate curtain fly line, a valance fly line and two winches for moving the safety curtains.
- Safety curtains: Two electric drum winches ensure the movement of the stage front and rear fire curtains. They are equipped with dual motors (service and emergency) and safety braking systems, ensuring stage insulation in the event of an emergency..
- Mobile stage opening catwalk: mobile structure used as a motorised vertical travel lighting bridge, operated by a 4-rope winch with dual motorisation (service and emergency), for the accurate positioning of lighting fixtures.
- Mobile stage opening towers: pair of mobile lateral structures that adjust the width of the proscenium, integrated with lighting fixtures and moved in synchronism by means of mechanical transmission.
- Multiple engageable winches: two special winches with 6 individually engageable drums, employed to lift large or heavy set elements, with flexibility in the arrangement of the lines.
Lower stage machinery
The lower stage machinery was subject to partial refurbishment and renewal of the electrical systems and control logic.
These consist of a series of integrated units for moving the stage floor and its mobile elements:
- 6 stage lifts: independent double-deck elements, moved by cable winches with roll and pitch control systems. They can be raised to stage height or lowered for variable stage configurations.
- 1 orchestra pit bridge: Semi-circular mobile structure positioned on the proscenium, which can be used as an extension of the stage or to accommodate the orchestra, moved by rack and pinion systems with counterweights and controlled from a dedicated station.
- 8 motorised lateral wagons: mobile platforms that can be positioned in the side wings openings, which can be coupled in different configurations.
- 1 rear stage wagon: motorised platform with eight independent control units. It is equipped with a hydraulic system for emergency lifting in the event of a breakdown.
Control system
The theatre has been equipped with the CURIO control system, which safely manages and monitors the machinery of the upper and lower stage machinery. Based on two separate controllers (one for safety, the other for performance), the system is modular and easily expandable. It meets Safety Integrated Level 3, in compliance with standard EN 61508.
To ensure the continuity of the theatre programming, the project was planned over two separate years, with a modular approach respecting the stage timings.
First phase:
Upper stage machinery
- Technical inspection and on-site surveys
- Mechanical and electrical design of new components
- Construction of the new lifting winches
- Dismantling and disposal of the old machines and related electrical panels and cables
- Installation of new machines, electrical panels and control consoles
- Commissioning tests and final inspections
Second phase:
Lower stage machinery
- Mechanical and electrical design of new components
- Construction of new components and accessories
- Dismantling and securing existing structures
- Installation of new machines, electrical panels and new control consoles
- Commissioning tests and final inspections
