They usually weigh it at the check in desk. Take your heavy stuff out and have whoever takes you to the airport hold onto your stuff whilst you check in. After checking in pick up your stuff an go through security![]()
I've flown with lots of different airlines, and never once had carry-on luggage weighed.
They might notice when it goes through the scanner that it is full of equipment though, and if so they would weigh it at that point.
