Patent ID: 8905250

Claim:
A crane comprising: an anti-two-block sensor connected to an anti-two-block control; a transmitter located proximate a boom tip of the crane and coupled with the anti-two-block control; a power generating device directly connected to said anti-two-block control, and configured to provide power to said anti-two-block sensor and said anti-two-block control, said power generating device being responsive to movement of a lifting cable of the crane for generating power; wherein said anti-two-block control is configured to generate a command sequence responsive to commencement of power flowing out of the power generating device, and wherein said transmitter is configured to generate an initiation signal responsive to said command sequence; a crane operation controller for controlling operations of said crane, said crane operation controller being responsive to said initiation signal for preventing operation of the crane in a manner that would result in two-blocking; wherein said transmitter wirelessly transmits the initiation signal to said crane operation controller in response to commencement of operation of said power generating device to actuate said crane operation controller to monitor and respond to control signals from said anti-two-block sensor in operation of said crane.
