There are only two fixed points at the bottom corners of the cab for the high and low grade air pipes, and there are no fixed points at corners, so the state after installation cannot be guaranteed. <br>There are only two fixed points at the bottom corners of the cab for the high and low air pipes, and there are no fixed points at corners, so the state after installation cannot be guaranteed. It causes interference between the air pipe and the plug of the auxiliary water tank liquid level sensor after the cab is assembled. <br>1. Interference between the air pipe and the plug will easily cause the plug to fall off during driving; <br>2. Long-term vibration interference may easily cause the air pipe to wear out; <br>it is recommended to add a fixed point at the slope of the corner to increase the distance between the air pipe and the auxiliary water tank.

There are only two fixed points at the bottom corner of the cab for high and low gear air pipes, and there is no fixed point at the corner, so the state after installation cannot be guaranteed.<br>There are only two fixed points at the bottom corner of the cab for high and low gear air pipes, and there is no fixed point at the corner, so the state after installation cannot be guaranteed. As a result, the air pipe after assembling the cab interferes with the plug of the liquid level sensor of the auxiliary water tank.<br>1. The interference between the air pipe and the plug is easy to cause the plug to fall off during driving;<br>2. Long time vibration interference is easy to cause air pipe wear;<br>It is recommended to add fixed points at the slope of the corner and increase the distance between the air pipe and the auxiliary water tank<br>

There are only two fixing points at the corner at the bottom of the cab for the high and low air pipes, and there is no fixing point at the bend, which cannot guarantee the installed state.There are only two fixing points at the corner at the bottom of the cab for the high and low air pipes, and there is no fixing point at the bend, which cannot guarantee the installed state. The rear air pipe of the assembled cab interferes with the plug of the auxiliary water tank liquid level sensor.1. The interference between the trachea and the plug easily leads to the plug falling off during driving;2. Long-term vibration interference is easy to cause tracheal wear;It is suggested that the fixed point should be added at the inclined plane of the corner to increase the distance between the air pipe and the auxiliary water tank.
