130903000088A001 Headrest Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

This product is an original factory-customized core safety accessory for the cab, compatible with various engineering machinery cab seats. Its core function is to provide stable support for the head and neck of the driver and passengers. In the event of vehicle bumps or rear-end collisions, it effectively buffers the impact force, limits excessive head tilting, and reduces the risk of cervical spine injury. It also features adjustable height and angle, breathability and comfort, and anti-shake and anti-slip functions, making it suitable for long-term working scenarios in mines and construction sites. It relieves neck fatigue of drivers and passengers, improves driving comfort and safety, and complies with relevant safety regulations for automotive seat headrests.
This product is precisely matched to the cab seats of SANY, XCMG, Caterpillar and other series of construction machinery. It adopts an integrated process of frame welding, PU foaming and surface covering, and is compatible with original factory seat installation positions. It can be installed quickly without complicated adjustments, can withstand harsh working conditions, and is firmly installed without loosening or shifting.

【Core Technical Parameters】

-Product Model: 130903000088A001
– Product Type: Headrest Assembly (Original Equipment Manufacturer, Safety and Comfort Headrest for Construction Machinery Cabs)
– Compatible models: Cabs for Sany, XCMG, Caterpillar, and other series of construction machinery; compatible with loaders, excavators, bulldozers, etc.; can directly replace original parts.
– Material: The internal frame is made of high-strength steel plate, the cushioning layer is made of high-density PU slow-rebound foam, and the outer skin is made of wear-resistant and flame-retardant fabric (PU leather optional). It undergoes welding, foaming, and coating processes. The steel plate has a tensile strength ≥500MPa, the PU foam density is 30-50kg/m³, and the fabric has a flame-retardant rating of UL94-V0.
– Operating temperature range: -30°C to +80°C (stable performance under extreme temperatures, no brittleness, no aging, no degradation in foam resilience, and no fading or cracking of the surface)
– Structural Specifications: Integrated assembly structure, including steel plate frame, PU cushioning layer, outer skin covering, height adjustment mechanism (rack and pinion), locking buckle, height adjustable range 80-120mm, angle micro-adjustable 5-10°, conforms to the natural curve of the head and neck, built-in anti-slip positioning structure, combining safety protection and comfortable support, meeting whiplash injury protection design requirements.
– Dimensions: Precisely fits the original factory seats; length, width, and height, as well as the spacing of the mounting pins, perfectly match the seat position and backrest. Dimensional tolerances are IT7-IT8 grade, with installation gaps ≤0.2mm. The headrest width is adapted to the head size of the driver and passengers.
-Installation method: Secured with a pin and locking clip, compatible with original seat mounting holes. Before installation, clean any burrs or dirt from the holes, insert the pin and lock. No professional tools required. After installation, the seat is stable, wobble-free, and allows for smooth adjustment.
– Protective performance: Waterproof, dustproof, and oil-resistant; surface is stain-resistant and easy to clean; salt spray resistance ≥480 hours; wear-resistant, aging-resistant, and UV-resistant; the frame is treated with anti-corrosion coating, making it rust-resistant; effectively withstands dusty and oily working conditions; the foam is not easily collapsed or deformed.
-Service life: ≥4 years under normal working conditions, ≥2 years under harsh working conditions; 10,000 height adjustment tests without failure; impact test meets GB 11550-2019 requirements; headrest backward displacement ≤105mm; foam resilience ≥75%; surface abrasion resistance ≥5,000 cycles.

Whether in bumpy environments, dusty mines, or extreme temperatures, this product consistently provides safety protection and comfort support, alleviating neck fatigue in drivers and passengers, reducing the risk of cervical spine injury in collisions, improving driving comfort and safety, and lowering maintenance costs. Original factory compatible and traceable with a unique code, it is a high-quality genuine part for headrest assembly repair and replacement, and for bulk stocking.
