Shield constructs quick -witted part hoist and mount composite set

The utility model provides a shield constructs quick -witted part hoist and mount composite set, includes connecting rod, crossbeam, lifting hook, bearing, bearing axle, first connecting axle, second connecting axle, and the connecting rod is connected with first overhead traveling crane a, second overhead traveling crane b through first connecting axle, and connecting rod and crossbeam are connected to the second connecting axle, and the crossbeam passes through bearing, bearing axle and hook connect, and the lifting hook forms swing joint with the help of bearing and crossbeam. The principle is with the help of connecting rod and connecting axle, focus on the crossbeam with two overhead traveling crane branch load on, leverage through the crossbeam focuses on the intermediate position with the branch load at crossbeam both ends and forms and close load, accomplishes the hoist and mount of these parts, the lifting hook passes through the bearing and forms swing joint with the crossbeam, satisfies the require
