发明名称 Elongated chain link.
摘要 An elongated chain link comprising a pair of opposing U-shaped end portions connected by a pair of parallel leg portions. The leg portions are connected to each other by a pair of crosswise tie-bars situated toward the end portions approximately equally offset from the cross-axial centerline of the link. Additional crosswise tie-bars may be added to prevent the legs of the link from collapsing together when a large side-load is applied to the link. The leg portions are substantially square in cross section, while the end portions comprise an inner portion having an arcuate inner surface and an outer portion being substantially rectangular in cross-section. The chain link is preferably made of a high-strength cast alloy steel and is especially well-suited for use in dragline drag and hoist chains.
