Hang
Hang turns up in 2 fields: powder coating, hydrography. Here is what it means to the people in each one.
Hang in powder coating
To load parts onto hooks or racks at the start of the line.
The loading station is where parts get hung, and the crew there are the hangers or loaders. How a part is hung sets where the contact mark lands, whether water drains from it in the washer, whether powder can reach every face and whether it swings into its neighbor. Hang density, often quoted as parts per hook or per foot, sets the line's output.
"Hang the brackets every other hook and turn them so the holes face down, they need to drain."
Hang in hydrography
In a wire drag sweep, the moment the wire catches on an obstruction, and the obstruction that caused it.
Wire drag talk for a snag: the drag wire catches on something rising above the set sweep depth, seen as the wire tightening and the marker buoys towing out of line. The crew marks the position, then divers, lead line or sonar find out what it is and how shallow it reaches. An area counts as clear only when every hang is explained.
"Hang on the west section at 9 metres, buoy it and get the divers down at slack water."
