This side window assembly is specifically designed for the cabin of Komatsu PC70 series excavators. As a critical component of the construction machinery safety glass system, this product features a combination of a black metal frame and safety glass, with a sliding opening function. It is designed to meet the visibility and ventilation requirements in construction machinery operating environments, while complying with the safety glass certification standards of major international markets.

1. Compliant Safety Glass Configuration:
The glass surface is clearly marked with CCC (China), E1/ECE (Europe), and DOT (USA) certification logos, indicating that the glass fully complies with vehicle safety glass regulations in China, the EU, and the US. It is a standard component for both export and domestic OEM applications. Manufactured with safety glass that meets standards such as JIS R3211, it provides the necessary strength to ensure basic safety for operators during work.

2. Robust Heavy-duty Frame Structure:
The window is fully enclosed by a black metal frame. Compared to pure rubber-bonded windows, this structure better accommodates the mounting holes of the excavator cabin door frame and offers superior resistance to deformation. It features a built-in dual-track sliding system that supports left-and-right sliding operation. The compact frame design ensures that the glass slides smoothly without jamming.

3. Practical Ergonomic Operation:
Equipped with dedicated black rectangular handles, the positioning is designed to align with ergonomic habits, allowing the operator to easily open and close the window with one hand from inside the cabin to adjust ventilation. The frame edges are designed with installation grooves for rubber weatherstripping, ensuring a tight seal when closed and minimizing dust intrusion into the cabin.
