The invention provides a container crane with double main trolleys. The container crane comprises a door frame (100), a front and back cross beam (200), a pull rod system (300), a power supply system (400), the seaside main trolley (500), the landside main trolley (600), lifting appliance systems (700), a hoisting system (800), a hosting steel wire rope traction system (900) and a control system used for controlling the systems. According to the container crane with the double main trolleys, the double hoisting systems of the double main trolleys are used for collaborative operation, so that the operation efficiency of the whole crane is effectively improved. The double main trolleys work in a collaborative and dividing mode, and remote control operation and automatic control are easy to realize. One rail and one slide wire power supply system are shared by the double main trolleys, the utilization rate of the rail and the power supply system is higher, and better economic efficiency is achieved. The problem that box alignment of double hoisting duplex lifting appliances is hard is avoided. The weight of the whole crane is much smaller than that of a double hoisting quay crane and that of a double-trolley quay crane, and the container crane is more suitable for wharfs with low bearing capacity.
