Currently, the number of yarns on one yarn spindle head ranges from a few thousand to tens of thousands. Each yarn needs to pass through heddles and drop wires. Sometimes, the weight of so many heddle frames and drop wires can reach more than 150 kilograms, and it is impossible for one or two people to lift them. The current technical method is to move the frame away and then use a forklift to place the heddle frame and drop wires on the yarn spindle head. This method is time-consuming and laborious.
