To provide a crane capable of consistently and reliably operating a trolley and a saddle without connecting the trolley to the saddle by a thick multi-core cabtire cable or the like.

The crane comprises a pair of saddles 1 moving along a pair of saddle rails 2, a trolley rail 4 with both ends thereof being connected to the saddles 1, a plurality of trolley cables 6 arranged along the trolley rails 4, a trolley 3 moving along the trolley rail 4 while being in contact with the trolley cables 6, and an operation unit 30 for transmitting a control signal to the saddles 1. The trolley cable 6 comprises a power line 6A for supplying the power, and a spare line 6B. The crane has a transmitter 8 which modulates the carrier by the control signal to be input from the operation unit 30 and outputs it to the spare line 6B in the saddles 1, and a receiver 9 which receives the carrier to be output to the spare line 6B and detects the control signal in the trolley 3, and receives the output of the transmitter 8 by the receiver 9 and controls the trolley 3.
