A222200000012 Door Lock Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The A222200000012 original factory door lock is a SANY original factory exclusive lock for cabs. Installed on the cab doors of construction machinery, it primarily secures the door, ensuring the cab’s airtightness, safety, and sound insulation. Equipment subjected to long-term outdoor vibrations, dust, and humidity can cause old door locks to malfunction, such as jammed latches, loosening, corrosion, locking failure, and improper door closure, leading to noise, dust and water ingress, and insufficient protection. This product utilizes original factory precision molding and an integrated precision structure, ensuring a tight lock body, vibration resistance, and anti-shake performance. It effectively prevents door loosening, noise, and pop-out during operation. The product meets SANY’s original factory quality inspection standards, and the standard hole positions require no modification. It can directly replace jammed, corroded, or malfunctioning old door locks. Suitable for equipment maintenance, fault repair, new machine assembly, and bulk stocking, it is ideal for heavy-duty working conditions such as infrastructure construction, mining, and earthmoving, ensuring a stable door closure, improving driving safety and comfort, and reducing maintenance costs.
