This component is an original protective and guiding device for the roller assembly of the five-section U-shaped boom telescopic mechanism. Its core is installed on the outside of the telescopic rollers (guide rollers/support rollers) to isolate interference, block foreign objects, constrain movement trajectory, and ensure operational safety. It is suitable for heavy-load conditions such as full extension/retraction and luffing limits of the QY50K-1 boom. It isolates the rollers from the telescopic cables, boom section web, hydraulic lines, and wiring harnesses to prevent friction, jamming, or collision; and prevents the wire rope from derailing and the boom section edge from scraping against the roller bearings/shaft ends, especially during boom extension and luffing limit operations.
