E-fence

An electronic fence is a boundary set in the machine’s control system that the bucket and boom are not allowed past. Set it, and the machine stops itself at the line — it doesn’t rely on the operator noticing in time.

You set them wherever something must not be touched: a depth limit above a service, a wall you cannot swing beyond, a ceiling under overhead powerlines, or a clear line beside a structure that has to stay standing.

Why it matters on your job

Most expensive damage on a site is not a machine going wrong. It’s a swing that goes a bit too far, or a bucket that goes a bit too deep, in a spot where there was no room for a bit. Hitting a service means a shutdown, an emergency repair bill, and a job that stops until someone else fixes it.

An e-fence turns “be careful there” into a limit the machine enforces every time, on every operator, all day — including at the end of a long one.

What it doesn’t replace

It’s a backstop, not a substitute for knowing what’s underground. We still run a Dial Before You Dig search before we start, still pothole to confirm what the plans claim, and still hand-dig the last of it near anything live. The fence is there for the moment when everything else has already been done properly.
