• Specification

• Function and Application

1. Guiding Window Movement
The primary function of the center rail is to serve as a precision guide for the sliding window panel in the operator’s cab. It provides a stable, linear track that allows the window to slide smoothly open or closed along a fixed path. This guided movement ensures the window operates with minimal friction and remains properly aligned, preventing jamming or misalignment during use.

2. Structural Support
The center rail acts as a reinforcing component for the cab window assembly. It helps maintain the structural integrity of the window frame, especially in heavy-duty environments where equipment is subject to vibration, impact, or rough terrain. By stabilizing the window panel, it reduces stress on the window glass and surrounding frame, extending their service life.
