The balance rib 72c is bridged between the horizontal bars 21 and 25. Similarly, when the hoist hole of the lower side of each horizontal bar hooks the same cargo or different cargoes, the horizontal bars can be more balanced with each other by the balancing bars 72a, 72b and 72 c.
Fig. 8 shows a flow chart of a method of using an auxiliary spreader for warehouse logistics, in accordance with another aspect of the present application.

Compared with the prior art, the auxiliary loading and unloading sling for the warehouse logistics is provided with the horizontal rods which are uniformly distributed along the circumference, the upper surface and the lower surface of the horizontal rods are respectively welded with the first traction part and the second traction part, the traction force provided by the crown block or the crane is conducted by the first traction part, the goods to be lifted are hooked by the second traction part, and the contact between the hook and the wrapping steel belt of the goods does not need manual intervention of workers, so that hand squeezing injury or compression injury is avoided. In addition, when copper rods or aluminum rod cylinders need to be stacked, workers do not need to carry out ascending operation on site to hook and unhook, and potential safety hazards of storage are further reduced.
Hereinabove, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those of ordinary skill in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the application without departing from the spirit and scope thereof. Such modifications and substitutions are intended to be within the scope of the following claims.
