The lower hanging ring 12 of the present application is provided on the first sliding frame 23 and the second sliding frame 24 so that the hanging chains thereon are connected to the hanging rings of the stamping die. The multiple hanging chains form a trapezoidal structure along the vertical plane to reduce the problem of inertial shaking during the movement of the hanger 1.

[0039] The working principle of this application is as follows: when in use, the gantry truck is hung on the upper lifting ring 11 through a lifting chain, and the hanger 1 is raised; the swivel 31 is rotated to drive the annular gear 311 on the swivel 31 to rotate, so as to drive the driven gear 33 to rotate, and the rotating shaft is used to make the active bevel gear 34 drive the driven bevel gear 35 to drive the screw 32 to rotate in the crossbeam 101 and the longitudinal beam 102, thereby pushing the first sliding frame 23 and / or the second sliding frame 24 to slide on the crossbeam 101 and the longitudinal beam 102 to adjust the angle between the crossbeam 101 and the longitudinal beam 102 to adapt to the balanced lifting of stamping dies of different sizes, and then rely on the lifting chain on the lower lifting ring 12 to hang with the lifting ring of the stamping die.
