Compressed air is essential for operating the brakes and air suspension on semi-trailers, which is why both the Trailer Mover 40To and Trailer Mover 20To are equipped with a compressor to ensure a sufficient air supply through the red and yellow hoses.
To make sure the system has enough pressure, we measure the air pressure in the hoses. In this case, the red connection shows 8 bar, which is sufficient to release the semi-trailer’s brakes and activate its air suspension.
Both the brakes and air suspension can then be adjusted using the control panel on the semi-trailer. ⚙️
