Tech/Engineering - Mechanics / Mech Engineering / pipe-bursting
English term or phrase: spinner
in a pipe-bursting machine (replaces existing underground water, gas lines by breaking them and at the same time setting the new line in place)

machine controls
"Push - tighten: rotates spinner clockwise"
"Pull - loosen: rotates spinner counter clockwise"

"Units without the Rod Spinner must be manually threaded and torqued together."

"Pull the rod spinner lever (6) back to engage the rod spinner and unthread the rods from each other."

...Is this a kind of wrench?
Thanks

Explanation:
It's hard to say much without seeing the actual equipment or good pictures of it, but in a mechanical context a spinner is something that rotates (or can be rotated) relatively freely about an axis. One example you'll find in the dicos is the cap on the hub of a propeller to streamline its shape; another is a device that was formerly used (until around the 1960's or so) to attach the wheel hubs of racing cars to their axles (much faster to dismount and mount than with a conventional set of lug nuts). A third example (and probably closer to what you have here) is a tool resembling a screwdriver but with a recessed socket at the end of the shaft, which is used to quickly thread nuts onto bolts (or unthread them, of course).

In your case, it sounds like it is a power-driven mechanical device that spins a rod or set of rods to thread them together or apart (faster or easier than doing it by hand).
