The upper front windshield of an excavator cab typically refers to the upper area of the windshield or a separate observation window. Its main purpose is to provide the operator with forward and upward visibility, increase lighting, and protect the operator from external environmental factors such as debris, dust, and wind and rain.

1. Common Names and Locations

Standard Name: In the construction machinery industry, this component is often referred to as the "Upper Front Windshield" or "Upper Observation Window." If designed as a separate window, it may also be called the "Front Skylight."

Location: It is located directly above the front of the cab, adjacent to the upper edge of the main windshield. In some excavator models, it is an openable ventilation window or a fixed glass panel used to supplement the main field of vision.

2. Main Functions

Expanded Visibility: Helps the operator observe the situation above the boom, stick, and working area in front (such as during hoisting operations or when approaching obstacles), improving operational safety.

Lighting and Ventilation: Increases natural light entering the cab, reducing eye fatigue; some designs can be opened to provide additional ventilation.

Safety Protection: Made of safety glass, it can withstand impacts and flying debris, and has UV protection, heat insulation, or anti-fog coatings to ensure operator comfort in harsh environments.
