Together they are supplying a rig that includes over three hundred ETC Source Fours and Source Four Pars, seventy conventional Par Cans, Arri 2.5K HMI fresnels and almost one hundred and fifty Wybron scrollers. To supply lighting designer Paul Pyant’s epic rig for this epic show, leading London-based lighting supplier White Light has teamed up with Q1 Production Technologies in Canada, who supplied equipment to the original production. These movements are loaded into the new control program Through this new programming interface, we have made tremendous time savings and allowed new opportunities for creative directors. Given the complexity of the revolve movements, these are programmed using a 3-D animation test package. On-line the status of each emergency stop is monitored so that the operator can easily see which emergency stop has been pressed. The emergency stop is fully wired and meets safety category 4. It allows the operator to speed up the moves and adapt to the actor without stopping the show. This is a proven concept and various other productions have shown its usefulness when dealing with complex moves. The operator has the various playbacks to control the speed of the programmed movements. The operation takes place at three different STS OptiStage2000 desks, Each desk is equipped with six playbacks, a Querty keyboard, emergency stop, DMBs, as well as the standard operating controls. There is a third IPC, to SIL 3 specification, which controls the air systems. Electronic data interchanges between the two IPCs is through slip rings. One of these IPCs is integrated into the revolve. The control system consists of 44 inverters, 21 hydraulic controls and digital I / O by two IPCs which are controlled via multiple CAN buses. This includes:ġ7 counter balanced winches for 400 kg flies Ģ single wire winches for special effects with a speed of 3 m/s Ħ winches for performer flying as part of the STS flight system Ī winch for five canvases that hang in a circle.Ģ1 Kabuki Drops, a release mechanism for canvases Ĥ trusses which are driven by an electric toothed belt Ģ props that move in all directions, fold up and are inflatable.
The complete hydraulic system, including the controller, is integrated into the revolve.
The scissor lifts move within the revolve. The showdeck consists of a 13 metre diameter revolve with 16 hydraulic scissor lifts and a centre lift. Silicon Theatre Scenery was responsible for the automation and control, including various winches and additional axes. Scenic Automation (from Silicon Theatre Scenery website)
