## What OperatorLink is built for

OperatorLink is made by the team that publishes this site. For a crane crew member, it shows STOP, HOLD and SLOW to the jobsite crew, and passes button presses, chat and voice between phones in a browser [^3]. A STOP releases every held direction on every phone and shows a full-screen alert to everyone else [^3]. HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves [^3]. Holding a move button keeps sending that move to the other phones, and if the move stops arriving for 2 seconds, the other phones drop it [^3]. One-tap radio-style calls such as Go Ahead, Copy That and All Clear are sent as chat messages [^3]. Anyone who joins can take part in a voice call run from the phone browser [^3].
