Description

technical field [0001] The invention relates to a closing / unloading device for double 40-foot container spreaders. Background technique [0002] At present, the port crane spreader can only lift one 40-foot container (or two 20-foot containers) at a time, which restricts the improvement of production efficiency. In order to further achieve high working efficiency, it is necessary to use two spreaders to simultaneously lift two 40-foot containers (or four 20-foot containers) at a time, and the first thing to solve is how to connect the two spreaders to the rack One problem. Contents of the invention [0003] The present invention provides a double 40-foot container spreader closing / unloading device for solving the problem that two spreaders can be closed and released accurately and quickly. [0004] The technical solution adopted by the present invention is that the closing / unloading device for double 40-foot container spreaders is characterized in that it includes at lea...
