Abstract
A performance venue having a dynamic load management system for use in managing loads. The system uses a dead man circuit as a means for determining the actual or anticipated dynamic load produced by moving loads, and then disables the system by opening the dead man circuit when too many loads are moved or selected to be moved. Preferably, the invention is embodied in a dead man circuit is pure hardware, and is free of software components. The invention also provides a method of controlling movement of loads in a performance venue having a plurality machines. In its basic form, the method comprises selecting at least one of the machines for movement, closing a dead man circuit, and opening the dead man circuit if the current in the dead man circuit falls outside a predetermined range.
