Abstract
Bridge-type grab ship unloaders are widely used in the ancillary docks of power plants,metallurgy,ports and other industries,and play an important role in ship unloading.By comparing the mechanical differential four-drum with the electric differential four-drum of bridge-type grab ship unloaders,including the internal structure and principle of the mechanical differential four-drum reducer such as the layout of the machine room and the winding way of steel wire ropes,the mechanism principle,machine room layout,steel wire rope winding and action logic of the electric differential four-drum,their advantages and disadvantages were analyzed in detail.In addition to that,the combination of engineering practice and maintenance issues led to different control methods and the differences in control logic for two types of ship unloaders.关键词
