The invention discloses a double-horizontal-boom crane. The double-horizontal-boom crane comprises a tower body, a foundation, a control and monitoring system, lifting mechanisms, cargo booms, a swimming flexible attachment device and a rotation assembly, wherein the bottom of the tower body is connected with the foundation; the two sets of cargo booms are arranged on the two sides of the tower body in a bilateral symmetry mode; the two sets of lifting mechanisms are arranged on the ground and connect lifting wire ropes with the cargo booms through universal wheels on the foundation and a rope passing wheel beam on the upper portion of the tower body. The rotation assembly is arranged in the position, below the cargo booms, of the tower body. The cargo booms are connected with a tower top through flexible pulling rods. The control and monitoring system is electrically connected with the lifting mechanisms. Two sets of independent lifting and amplitude changing systems are provided, control is achieved in a concentrated mode through the same operation system, and therefore bilateral synchronous and asynchronous operation can be achieved flexibly as needed, and working efficiency is improved. The cargo booms are symmetrically arranged and can operate simultaneously, and an engineering building structure in a central symmetry mode can obtain higher operation efficiency.
