A luffing encoder mounting mechanism of a marine crane comprises an encoder, a positioning shaft, a connecting shaft, an arm support connecting support, a first mounting support and a second mounting support, a conical shaft section at the front end of the positioning shaft is connected with a center hole of an arm support rotating shaft in a sleeved mode, and the first mounting support comprises an upper mounting circular plate and a lower mounting circular plate. A center hole of the upper mounting circular plate and a center hole of the lower mounting circular plate are located in the same straight line, the rear end of the positioning shaft penetrates through the center hole of the upper mounting circular plate and is fixedly connected with the fixed end of the arm support connecting support sleeved with the center hole of the lower mounting circular plate, and a kidney-shaped hole in the fixed end of the arm support connecting support is fixedly connected with one end of the connecting shaft. The connecting shaft is sleeved in the second mounting bracket through a rolling bearing; and the rear end of the connecting shaft is connected with an input shaft of an encoder sleeved in the second mounting bracket. According to the mechanism, the variable-amplitude angle of the boom is recorded through the encoder, the working radius of the crane is obtained, interference of ship state factors is avoided, and the accuracy is high.
