This is a lightweight sliding window assembly specifically designed for the side doors of Komatsu excavator cabins. The product features a precision black metal frame encapsulating a single pane of safety glass. Its contour has been custom-cut to match the lines of the cabin door frame (with special attention to the rounded arc in the upper left corner), ensuring a perfect fit after installation. As a light-duty window, it effectively controls the overall weight while maintaining clear visibility and operational flexibility, making it a standard accessory that balances cost-effectiveness and practicality.
Product Advantages
1. Customized Irregular Frame Process
Unlike standard rectangular windows, this window features a specific rounded/cut-corner design in the upper left corner, strictly corresponding to the door frame shape of Komatsu excavator cabins. This high-precision molding process ensures uniform gaps when the window is embedded into the door panel, providing a strong OEM-like appearance and avoiding the poor fitment issues commonly seen with universal parts.
2. Lightweight Single-Glass Design
High-strength single-pane tempered glass is used instead of a bulky double-pane structure, significantly reducing the overall weight. For excavator side doors, reducing the window's weight effectively lowers the long-term load on door hinges and limiters, preventing door sagging or operational noise caused by gravity, and extending the service life of the door mechanism.
3. Dual Independent Control Layout
Both the front and rear glass panes are equipped with independent black rectangular handles, supporting overlapping sliding in either direction. The operator can flexibly adjust the opening size based on wind direction or cooling needs, ensuring both operational convenience and excellent side visibility.
4. Certified Compliance and Safety Details
The corners of the glass are clearly marked with international safety certification logos such as CCC and E1/ECE, complying with safety regulations for construction machinery vehicles. The edges of the frame are blunted and feature pre-installed weatherstrip grooves, providing basic protection while meeting the dust-proof requirements of daily operations.
