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.
