A mine air crossing includes opposite side walls and a deck extending from side wall to side wall. One or more alignment lights may be provided, along with mounts for adjusting the positioning of the lights and sensor. A separate mechanism provides a count of available credits from the receiver, the separate mechanism not necessarily being current. Each air spring is disposed between an L arm rigidly attached to the trike swing arm, and the trike frame. The apparatus also has a pair of connecting devices positioned opposite of each other.
