During a staging rehearsal, a seven-point winch array lifts a 1.2-ton truss toward the flying batten. The operator presses GO, and the truss either climbs level or develops a visible skew that grows as it rises. That difference is rarely caused by the mechanical hardware alone. It is caused by how ...

Your stage manager calls at 7:45 PM. The third act needs a 12-foot painted flat to fly in at 9/8 of a meter per second, and the counterweight set on line 15 is currently three iron plates over weight.
