[0002] Port terminals are busy with production, especially in recent years, with more and more oversized containers being handled, and the workload has increased by 45% year-on-year compared to the past. The utilization rate of super-high frames (also known as "super-high container slings") is getting higher and higher. In the past, because the telescopic beams of the super-high frames were not equipped with support roller devices, the telescopic beams of the super-high frames were only supported by anti-modules. During the operation, the telescopic beams of the super-high frames were often difficult to extend and retract, which easily caused the telescopic beams to get stuck and move. Two forklifts were then required to assist in the folding of the beams on both sides. This affected the operating efficiency and affected the ship operation plan and progress of the terminal. At present, there is a lack of a support roller device suitable for the telescopic beams of the super-high frames to facilitate the normal extension and retraction of the telescopic beams of the super-high frames and to avoid the jamming of the telescopic beams of the super-high frames during the extension and retraction process to the greatest extent.
