All products are verified by the most rigorous tests and field tests in the worst conditions，The lubricating chain rail adopts the specially-supplied agreement steel jointly developed with well-known domestic steel mills The performance indicators of raw materials have higher and stricter requirements Introduced automatic forging production line for chain rail links in Germany Realize the automatic production of chain rail section forging。

Adopt self-designed special heat treatment equipment，The depth of the hardened layer is increased by 20%, which is more wear-resistant，MT flaw detection on all chain links more stable quality。All series of lubricating pin sleeves are carburized for higher hardness，Pin bushing wear life increased by 50%!

Chain link processing adopts combined fine milling process with independent intellectual property rights，Adopt international advanced CNC machining center，All end faces of lubricating pin sleeves are specially treated，Seal reliability increased by 30%! Fully automatic lubricating crawler assembly line, online full sealing test，Adopt sealing components jointly developed with international famous brands and patented formula lubricating oil Better lubrication and more reliability The life of the chain rail is increased by more than 50%!
