Cables, oil pipes, gas pipes, water pipes, and air ducts commonly used on machine tools and other mechanical equipment for traction and maintenance purposes. The application of steel cable carriers originated in Germany, later introduced and innovated domestically. Today's steel cable carriers are widely used on machine tools, protecting cables and enhancing the overall appearance of the machinery. Traction chains, rectangular metal hoses, protective sleeves, bellows, and sheathed metal hoses all fall under cable protection products. Steel cable carriers are categorized into three types based on different application environments and requirements: bridge-type steel cable carrier, fully enclosed steel cable carrier, and semi-enclosed steel cable carrier.
