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 phone 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 messages such as Go Ahead, Copy That and All Clear are sent as chat ^[3]. Anyone who joins can take part in a voice call run from the phone browser ^[3].

Setting it up on a jobsite

OperatorLink runs in a phone browser with no app install ^[3]. The person who starts a jobsite shares a link or QR code, and the crew joins from it ^[3]. Phones can add the app to their home screen as a standalone app ^[3]. A jobsite link stops working 12 hours after the first person joins ^[3], and a jobsite with nobody in it is wiped after 3 idle hours ^[3]. Button presses, chat and voice pass between phones in the browser ^[3]. For Crewplex, the facts gathered here do not describe how a crew is added to a system, how signals pass, or how a jobsite is started.

Things to check before you choose

How many people will be on the crew, and does the size match the Crewplex system you are looking at? CrewPlex describes a small system for small crews and a large system for larger crews ^[1] ^[1].

Does the crew already use two-way radios, and would optional integration with them matter? CrewPlex says it offers that integration ^[1].

Which headset style does the crew need? CrewPlex offers a full range of headset options that fit a variety of jobs and applications ^[1].

Which David Clark Company product line matches the crew's work, and does the crew need mission-critical hardware rather than a phone-based tool? ^[2]

Does a jobsite link that stops working 12 hours after the first person joins suit the crew's shifts? ^[3]

Which signals does the crew need on a jobsite, and how will the crew test that each tool passes them before a lift?
