CASE STUDY IN THE FIELD

Out in the Jost factory parking lot in Frankfurt, CM witnessed and tried coupling a MAN to a tri-axle curtainsider. Despite a slight slope to the ground, the sensors soon worked out what was where, lined up the plug-in and opened the docking sockets ready to link the services.
Once the trailer and tractor sensors were happy everything was hooked up, the air suspension levelled automatically. Only when a green in-cab light indicated everything was completed could the rig be moved (when uncoupling, the filth wheel is opened by an air release).
In the connecting wedges, there are individual pins and sockets for every electrical connection (28 in all, with radiused edges for a tight f tt), so there's no need for data conversion or CAN-bus transmission. There's also two synchronised air connections and three alignment pins, one in the centre and one at each side, to pull the connection straight.
