Running a Line Set
Only trained crew members are allowed to run the fly system.
All line sets must be kept in a balanced state. Never rely on the rope locks to hold an unbalanced line. The rope locks can hold a maximum of 50 pounds out-of-balance before slipping.
At least two people are required to fly in or fly out a line.
Gloves should be used by the operator when running a line.
Before raising or lowering a line the line operator calls out “Line xx coming in” or “Line xx going out”.
The operator must then WAIT for a “clear” from the spotter.
The line operator holds the appropriate line (Back for OUT/up, Front for IN/down) while releasing the break. The line should be moved smoothly.
The spotter is responsible for verifying that the space under the batten is clear and remains clear while the line is moving. The operator should call STOP if someone enters the lane of the batten.
The line operator reports to the spotter when the line is locked (“Line Locked”, or “Clear”).
During shows, verbal call-outs are not required, but all actors must be taught when and where lines will be coming in and out and a spotter must still watch the lanes.
