The invention discloses a double-bridge crane. The double-bridge crane comprises a first strut; a second strut is arranged on the left side of the first strut; a slide rail is fixedly arranged betweenthe first strut and the second strut; a rack is arranged in the slide rail; a roller slideway fixedly arranged between the first strut and the second strut is arranged below the slide rail; the roller slideway is symmetrically arranged back and forth by taking the slide rail as a center; a first steel cable rotating wheel is arranged in the first strut; and a first steel cable is fixedly arrangedon the outer circular surface of the first steel cable rotating wheel. According to the invention, left and right sliding of a sling trolley and stretch and retraction of the first steel cable can berealized through a single motor, so that the cost is saved, and stability of the double-bridge crane is ensured by separating movement of the sling trolley and stretch and retraction of the first steel cable. According to the invention, the first steel cable can be lubricated and maintained in a process of stretching and retracting the first steel cable, so that the steel cable is prevented frombeing corroded and clamped, and the service life of the first steel cable is prolonged.
