The short answer

A crane crew member needs to get signals to the whole crew while the crane moves. OperatorLink shows STOP, HOLD and SLOW to the jobsite crew and passes button presses, chat and voice between phones in a browser ^[1].

Sonetics is named on this page, but the facts gathered say nothing about what it does, so this page cannot describe it. A crew should decide whether it wants signals handled through phones or through a wireless headset system.

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 ^[1]. A STOP releases every held direction on every phone and shows a full-screen alert to everyone else ^[1]. HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves ^[1]. 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 ^[1]. One-tap messages such as Go Ahead, Copy That and All Clear are sent as chat ^[1]. Anyone who joins can take part in a voice call run from the phone browser ^[1].
