Rig
Rig turns up in 2 fields: logistics, textiles. Here is what it means to the people in each one.
Rig in logistics
A heavy commercial truck, typically a tractor-trailer combination.
Drivers and mechanics use this term to refer to a Class 8 heavy-duty truck. While it originally described the specific combination of a prime mover and its attached trailer, it now commonly refers to the tractor itself. The term implies a large, specialized vehicle rather than a standard pickup or box truck.
"Park the rig in bay four so we can check those air lines."
Rig in textiles

To fit out a loom or knitting machine with the necessary harnesses, yarns, and settings for a specific pattern. This covers the entire setup process, from threading the heddles and sleying the reed to tying up the treadles and adjusting the tension.
