PRG’s Drive Rack can drive a wide variety of motion control and automated effects in the Stage Command System. Each Drive Rack contains either four 3kW drives or two 7kW drives depending upon the horsepower of the specific motor being driven. The 3kW Drive Rack will drive four axes of motion and the 7kW Drive Rack will drive two axes of motion. Among the many motion effects driven by the Drive Rack are winches for deck tracks, counterweight-assist for flying, dead haul, traveler tracks, turntables, lifts and sloat lifts, turtle rotators, and chain hoists. The drivers are housed in a custom- designed road case, allowing them to withstand the rigors of touring and transport.
