According to the working principle of the drag chain, after the drag chain block is hinged, it can only rotate along the center of the hinge hole within a certain angle range, so that it can drive the cable to move with the traveling crane. That is to say, the drag chain moves by the radial tension acting on its rotation direction when the crane moves. The trolley drag chain is rigidly connected with its fixed frame, while the trolley is moving on the track, which is affected by various external forces during its movement, making its movement track unable to maintain a straight line. That is to say, when the traveling crane moves on the track, it also moves left and right. In this way, the drag chain rigidly connected to the traveling crane will also move from left to right. Therefore, the suspended part of the drag chain is subject to the gravity of itself and the cable, as well as the traction force of the traveling crane, and also to irregular torque, making the drag chain block more complex and prone to fatigue bending.
