SSY004939826 Front Left Door Hook Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004939826 original left front door wind hook is a SANY original factory cab-specific wind hook accessory, installed on the left front door of construction machinery. Its core functions include limiting door opening, fixing the opening angle, and preventing wind and swaying. During equipment operation, it effectively locks the door opening angle, preventing the door from swinging freely, impacting the vehicle body, causing abnormal noises, and sustaining damage from bumps and knocks under strong winds and rough conditions, protecting the door hinges and lock structure. The original standard hole positions require no modification, directly replacing old wind hooks that are deformed, rusted, broken, have failed elasticity, or have malfunctioning limit switches. It is suitable for routine equipment maintenance, fault repair, new machine assembly, and bulk stocking. Precisely molded from the original factory, the curvature and positioning are accurate, ensuring smooth opening and closing and a secure limit switch, preventing problems such as jamming, hook detachment, or limit switch failure. Suitable for harsh outdoor working conditions such as mining, earthmoving, and infrastructure construction, with surface anti-corrosion and anti-rust treatment, it is resistant to oil stains, aging, and wear. It is not easy to rust or jam during long-term outdoor operation, effectively stabilizes the opening and closing of the doors, reduces the noise from body collisions, and lowers the maintenance cost of cab parts.
