1.Use the crane hook to hook the ring of the vacuum lifter.
2.Please confirm the position of the vacuum lifter, it should be in the correct position of the lifted workpiece, and then control the crane hook to make the chain of the vacuum lifter slack.
3.Operate the crane to move upward to make the chain tighten. At this time, confirm the adsorption state of the workpiece (the negative pressure gauge pointer has an upward trend,which means that a vacuum has been generated and the lifting conditions are available).
4.At this time, operate the truck and move the workpiece to the designated place.
5.When arriving at the designated transportation destination, after confirming the placement position of the workpiece, control the crane to move downwards until the hoisting chain of the vacuum lifter is completely relaxed.
6.Pull up the lifting chain of the vacuum lifter again, the pointer of the negative pressure gauge no longer rises, and the workpiece is separated from the vacuum lifter.
7.Operate the driving to let the vacuum lifter go down until the hoisting chain is slack, repeat the above operation, and then the next workpiece can be adsorbed.
