The invention discloses a single-beam shipbuilding gantry crane. The single-beam shipbuilding gantry crane comprises a gantry structure and hoisting trolleys, wherein the gantry structure is composed of a main beam, a rigid leg and a flexible leg. The single beam shipbuilding gantry crane is characterized in that the main beam is of an inverted-trapezoidal box single main beam structure, the two hoisting trolleys are arranged on the upper flange edge panel of the main beam, and the two hoisting trolleys are on the same rail; the two hoisting trolleys walk on the main beam through the rail, the rail is fixedly connected with the main beam, and the hoisting trolleys are connected with the rail in a rolling manner; and two lifting hooks are arranged below the hoisting trolleys, and a revolution lifting appliance is arranged below the two lifting hooks of one of the two hoisting trolleys. Compared with the prior art, the single beam shipbuilding gantry crane has the beneficial effects that the overturn of a lifted piece is flexible and convenient, and more hoisting operation requirements can be met through the adjustment of the hoisting capacity of the two hoisting trolleys or the flexible allocation of the load ratios; the structure of the main beam is simple, stress is good; the running and operation and the daily maintenance are convenient, and the manufacturing and operating costs are reduced; and the collaborative operation of the two hoisting trolleys is improved, and the safety is improved.
