When the steel billet slides down from the sliding plate of the hoister, the equipment is easily damaged due to frequent collision because the impact force of the steel billet is large, so that the production is influenced. Therefore, a steel billet buffering device is required to be installed to buffer the gliding process of the steel billet and release the impact force of the steel billet so as to protect equipment from being damaged by collision and ensure the smooth production. In the prior art, damping is generally performed in the form of a spring damper driven by a hydraulic or pneumatic element.
