Double 40ft double trolley container crane is the combination of advantages of double 40ft container crane and double trolley container crane. It is the world most effective crane. ZPMC created double 40ft double trolley container crane (refer to the following photo) can handle 80~100 units of 40ft containers per hour theoretically. It is the world fastest crane.

Its structure and handling mode is similar to the double trolley container crane. It is also composed of main trolley, transmit platform and aft trolley.

It has the following features:

1、; There are two trolleys, one higher and one lower. The hoisting height of the fore trolley is above 40m that is for handling vessel. The hoisting height of the aft trolley is below 15m that is for picking up container from the transmit platform to chasses of only 1m high (or AGV).

2、; The fore trolley is same as that of the double 40ft container crane, and can hoist two 40ft containers at one time from the vessel to the transit platform (or vice versa). Because the two adjacent 40ft containers are regularly arranged on the vessel and the transmit platform, the two spreaders of the fore trolley can easily position and handle. The fore trolley can return for the second cycle of operation after loading or offloading the container. The productivity of the fore trolley is the productivity of the whole crane. It is basically semi-automatic operation, and the cab can be separable with the trolley.

3、;The aft trolley is equipped with one standard spreaders. The container handling points can be either inside the portal frame, or under the crane backreach (vessel hatch is placed inside the portal frame). In accordance with the terminal operation workmanship, it can handle one chassis or one AGV, or two chasses simultaneously. Because the hoisting height of the aft trolley is lower and the special wire rope reeving method is adopted, the spreader and container can have no sway, and the positioning is easy. The productivity is greatly increased.

its basic parameters are as follows:

Double 40ft double trolley container crane is an outcome of the Super-Panamax era after the emergence of double trolley container crane and double 40ft container crane. Its good performance and high-efficiency have brought attention to ports all over the world. It is ZPMC’s task to provide high quality, high efficient and high performance products at reasonable price to all ports in the world.We believe, after the double trolley container crane and double 40ft container crane are applied at ports, the double 40ft double trolley container crane will be approved gradually by port experts in the world, and will bring more benefit to container terminals all over the world.

The twin 40’quayside container crane is ZPMC’s newest design, offering fast loading and unloading to meet the demands of macro-scale vessels．;ZPMC has signed a contract to provide Dubai with four(4)twin 40' container cranes by early 2005．;The new crane can boost productivity by 50％; if loading and unloading techniques are improved accordingly．;

Main features：;

1．;The re are two independent hoisting system sets，;connected by the upper sheave of the trolley and two standard detachable telescopic spreaders．;The spreader headblocks can change relative positions (separating，;folding and‘V’shape) via oil cylinder to hoist two 40’ containers．;

2．;The crane does not simply unite two sets of hoisting machinery．;One of its significant features is the special differential hoisting gear reducer．;The reducer may dissociate and superpose power--that is，;it can distribute the output power of the two motors to the two spreaders, as well as direct all the power to one spreader．;Thus，;the crane can offer high speed and high efficiency while using one spreader.
