Tectra Automation Gives Rocky Horror Show a Lift

Tectra Automaton has designed, manufactured, commissioned and installed a custom stage lift for the Victory Theatre’s Rocky Horror Show in just two weeks.

Tectra used BoschRexroth components including an aluminium profile system, a servo motor and braking system. The lift – with a 500kg carrying capacity – allows actors to step on the lowered platform 2m beneath the stage and rise up to 1.1m above the stage floor, with 3 pre-programmed level settings, controlled by a chain-driven servo motor.

Instead of using a normal electric motor, Tectra used a servo motor, which is said to be more accurate with easier acceleration. Additionally, the combination of duplex chain drives, bevel helical gearbox and the servo motor ensures stability and smooth running with minimal noise.
Tectra divisional Manager of Linear Motion and Assembly Technology, Kevin Lombard says: “Safety of the cast is ensured though the use of an independent 650Nm braking system making sure there is zero runback in the event of mechanical or electrical failure.” An added safety feature is the door locking mechanism, fitted with isolator switches preventing the unit from being operated independently. Tectra also provided training with the theatre stage handler on the lift operation.

The actors and theatre staff are satisfied with the stage lift, Lombard says, and while it was initially decided that the lift would be used 4 times during one performance, it was used 9 times for various scenes and applications.
