13285766 Sany SY485C1 hydraulic excavator right door assembly

The right-side door assembly of the SANY SY485C1 hydraulic excavator (model 13285766) is a key integrated component for side protection and personnel access to the cab. Manufactured strictly according to SANY’s original design drawings, dimensional tolerances, and process specifications, it is specifically designed for harsh working conditions such as mining, infrastructure construction, and earthmoving, characterized by high dust levels, strong impacts, and fluctuating high and low temperatures. Serving as a safety barrier for the driver’s side and a window for observing the side working environment, it integrates multiple functions including window lifting, door lock control, and sound insulation. It ensures personnel safety while improving driving comfort and is a high-quality original factory replacement assembly for damaged or worn-out SY485C1 excavator doors.

The right-side door assembly is constructed from a high-strength cold-rolled steel sheet, integrally stamped and formed into a frame. It undergoes robotic welding and reinforcement, resulting in a highly rigid structure and excellent impact resistance. This effectively withstands external impacts such as flying debris and minor collisions during construction, preventing deformation and damage. The inner door panel is equipped with anti-collision steel beams and sound and heat insulation cotton, enhancing passive safety protection while blocking external construction noise and heat conduction, improving the quietness and temperature stability of the cab. The door glass uses original factory-made tempered safety glass with high light transmittance and no optical distortion. Combined with an electric/manual lifting mechanism (compatible with original vehicle configuration), the lifting is smooth, precise, and free of jamming or abnormal noise. EPDM sealing strips are inlaid around the glass, providing lasting elasticity and a tight seal, effectively preventing dust, rainwater, and mud from entering the cab.

The doors are equipped with original factory standard door lock assemblies, inner and outer door handles, and limiters, ensuring a secure lock and easy opening. The limiters precisely control the door opening angle, preventing automatic opening and closing due to operational vibrations. All hinge and latch holes precisely match the original cab frame, and a complete set of installation accessories (bolts, washers, sealant) is included, allowing for direct, seamless installation without welding or drilling modifications. The door surface uses the same three-layer coating process as the entire machine (epoxy primer + polyester intermediate coat + polyurethane topcoat), resulting in a uniform coating with strong adhesion, corrosion resistance, and UV resistance. It is resistant to fading and peeling during long-term outdoor operation, maintaining a consistent appearance with the overall machine.
