The invention provides a double-telescopic self-balancing
tower crane for a cargo ship. At ordinary times, a telescopic base
assembly and a telescopic self-balancing crane jib
assembly in the double-telescopic self-balancing
tower crane are contracted, so that the double-telescopic self-balancing
tower crane is stopped; during working, the double-telescopic self-balancing
tower crane for the cargoship is not limited completely and regionally; and with a telescopic self-balancing crane jib
assembly capable of lifting and rotating and a hoisting mechanism inside, cargos can be loaded and unloaded directly at a small or large space between the ship and a
wharf, so that the dependency on a
wharf crane is eliminated. The double-telescopic self-balancing
tower crane for the cargo ship is characterized in that the double-telescopic self-balancing
tower crane is hoisted on the cargo ship, and at ordinary times, the telescopic base assembly and the telescopic self-balancing crane jib assemblyin the double-telescopic self-balancing tower crane are contracted, so that the double-telescopic self-balancing tower crane is stopped; and according to the double-telescopic self-balancing tower crane, the telescopic base assembly is arranged on the cargo ship, and a telescopic self-balancing crane jib assembly is placed on a rotating assembly in the telescopic base assembly.
