1. A construction equipment lockout control system, comprising: a) at least one receiver including an equipment inhibitor for disabling at least one function performed by said construction equipment; b) at least one portable transmitter operable by an operator associated with said construction equipment, including circuitry for generating a radio signal in periodic bursts receivable by said receiver to enable the operation of said at least one function performed by said construction equipment; c) means for rendering said equipment inhibitor effective to disable the operation of said at least one function performed by said construction equipment and means for rendering said equipment inhibitor ineffective, so long as said radio signal from each of said at least one portable transmitters continues to be received by said receiver in periodic bursts, such that whenever said radio signal from any of said at least one transmitters is not received by said receiver said equipment inhibitor is rendered effective; and d) said portable transmitter including means for broadcasting a stop signal upon actuation of an operator actuable stop member forming part of said transmitter, wherein broadcast of said stop signal activates said equipment inhibitor to disable said at least one function.
