Abstract: The invention is a container lifter which is able to lift two 40 foot containers at a time. It includes two sets of the crane main lifting mechanisms with the wire rope winding systems being separate. Pulleys arranged at the crane upper frame cooperate with two lifting pulley groups arranged on the carrier. The first crane lifting mechanism and the second crane lifting mechanism are equipped with a barrel, a crane lifting mechanism motor, a brake and a crane lifting reduction gear box respectively The two sets of the crane lifting mechanisms are synchronously operated. By using the container lifter of the invention, the efficiency of the load and unload is increased, high repayment is obtained with less increasing the equipment cost, the larger beneficial result is occurred, also it has the wider applicable prospect.

Abstract: The present invention discloses an arrangement scheme of a container wharf, in which the containers positioned in the yard is arranged in a direction being perpendicular to the direction of the containers positioned in the ship, comprising: a quayside container crane for loading/unloading containers in the first direction; a low elevated system including low elevated track, low elevated system lifting trolley and low elevated system plane carriers, the low elevated system plane carrier can be operated by the low elevated system lifting trolley and the low elevated system can be operated by the quayside container crane; a transportation carriers system including transportation carrier track along the second direction and transportation carriers being able to rotate 90 degrees together with container put thereon, the transportation system can be operated by the low elevated system; a yard crane having a yard crane track along the second direction for loading/unloading the containers with the yard.
