Abstract A brand-new jib-bridge luffing system of crane is brought out based o analysis of the limitation to handle containers of the portal crane. The system is provided with novel structure and advantages, such as more rapid velocity, bigger tasking area, higher working efficiency, less weight, lower cost, and so on. The design methods are expounded of equalizing horizontal and balancing deadweight for the jib-bridge system. The optimizing design for the equalizing system ensured cargo to move horizontally in luffing process, the design method of balancing system achieved ideally effect.
