Bamberg: E.T.A. Hoffmann Theatre

Stage machinery

Under machinery

Four stage platforms with spindle drive and inclining floors were installed. Stage wagons and a turntable, built of frames, can be lowered with the platforms to form an even surface. For a possible future employment of a turntable wagon, guiding rails were installed in the stage floor. A motor driven orchestra platform (lifting height from –1,00m to +1,00 m) reduces the installation time to a few minutes.

Cloth store

The space in the understage behind the platform was used for the installation of a cloth store. It consists of 10.40 m long storage spaces that can be served directly from the stage.
Lifting height:
From +-0,00m to +2,40 m
Dynamic load: 40,00 kN

Upper machinery

For financial reasons, half of the fly bars are manual, the others are driven by electric motors. It can easily be converted into a completely motorized installation. The actual installation consists of seven electrically driven fly bars and one acoustic curtain, the other bars are operated manually. The flies are operated by an electronic command class 5. All drives can be moved individually, in groups and synchronically.
The portal consists of two fixed portal towers with a vertically moving bridge. The portal has a fixed opening width of 8,00 m. The lighting bridge can be moved from +1,00m to +7,50 m.

The following fly bars were installed:

• 7 electric flies, dynamic load 5,0 kN
• 1 electric fly bar for the acoustic curtain
• 18 manual flies, dynamic load 3,0 kN
• 2 manual panorama flies, dynamic load 3,0 kN
• 2 manual portal flies, dynamic load 3,0 kN
• 2 manual gallery lighting bars, dynamic load 3,0 kN
• 4 manual backstage flies, dynamic load 3,0 kN
• 1 electric forestage flybar, dynamic load 3,0 kN
• 1 electric fly bar for the lustre, dynamic load 5,0 kN

The portal consists of two fix lighting towers with a vertically moving lighting bridge. The lighting portal has a fix opening of 8,00m. The lighting bridge can be moved between +1,00m and +7,50 m.
Dynamic load of the lighting bridge: 25,00 kN
Speed: 0,10 m/s.
