is matched with CD1, MD 1type electric hoist. It is mainly applied to port, the freight yard and other outwork places for material handling. Electric equipment for the trolley adopts soft conductive cable’ It adopts closed air conditioning house with linkage platform control, so it has the advantages of broad vision, flexibile control, comfort work, and high efficiency.

. MG type gantry crane is mainly applied to port, the freight yard and other outwork places for material handling.
(1)The crane is in coordination control by converter start signal and mechanical braking signal. The crane carries weights by the converter, and then is stopped by the mechanical brake so the two signals must not be repeated. The best is to make sure the crane to implement one command of a signal at one time.
(2)When cranes are started, the pull-in torque should be big enough. Generally safe specification requires no less than 150% of the nominal torque; actually in the workplaces voltage is so changeable that the crane is beyond the reach of rated requirements. Therefore, when started, the crane should supply more than 200% of nominal torque in order to ensure safety factor high enough.
(3) The whole crane has these advanfages like heavy loading, wide span, flexible operation,. novel structure, attractive appearance, and advanced technology. The spare parts are standardization, generalization and serialization.
Energy feedbacks. There are vertical and horizontal traveling in the working course of the crane. When the urgent reduction happens, because of continuous rotation inertia, the motor will generate renewable power which will be feedbacked.
