Swapped from hand signals to radios on a blind pour in Houston and it saved the whole morning
Last month we were pouring a foundation at a site in Houston and the operator cab couldn't see the north side at all, so we tried hand signals like usual. Halfway through the first truck the signal guy got blocked by a rebar bundle and the operator just stopped dead, and we lost about 40 minutes. The next morning the foreman handed out two-way radios with a dedicated channel and it was night and day. The operator could hear exactly where the load was going and we finished the pour by lunch instead of pushing it into overtime. Now I'm wondering if we should use radios on every job where the cab has a blind spot, or if there are setups where hand signals still work better for you all?
