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 crew and passes button presses, chat and voice between phones in a phone browser ^[1]. No David Clark Company facts are detailed in this section. The cited facts do not describe its crane signal handling, so a crew with that need should check it directly with David Clark Company. A crew that needs STOP, HOLD and SLOW on phones in a browser has that need covered, and a crew that wants other communication options should ask David Clark Company what products it offers.

What David Clark Company is built for

A crane crew member who wants to know what David Clark Company is built for should ask the company directly. The crew should ask about its communication systems, including any mobile or stationary products it provides for jobsite safety.

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 ^[1]. A STOP stops every phone's moves and shows a full-screen alert to everyone else ^[1]. HOLD and SLOW stay on for the whole jobsite until everyone has left ^[1]. Holding a move button keeps that move going on the other phones, and the move stops if it fails to arrive for 2 seconds ^[1]. One-tap messages such as Go Ahead, Copy That and All Clear are sent to the crew as messages ^[1]. Anyone who joins can take part in a voice call run from the phone browser ^[1].

Pricing and fees

No price for David Clark Company is published here. A crew that wants to know what David Clark Company charges for its products, or whether it has monthly fees or setup costs, should ask the company directly before choosing. OperatorLink is currently free to use, and no paid plan is built yet ^[1]. The card fee is not published for either option, so a crew that expects to pay a card fee should ask each provider for it before choosing.

Setting it up on a jobsite

OperatorLink runs in a phone browser with no app install ^[1]. The person who starts a jobsite shares a link or QR code, and the crew joins from it ^[1]. Phones can add the app to their home screen as a standalone app ^[1]. A jobsite link stops working 12 hours after the first person joins ^[1], and a jobsite with nobody in it is wiped after 3 idle hours ^[1]. Button presses, chat and voice pass between phones in the browser ^[1].

This section does not describe how David Clark Company sets up its products. The crew should ask the company how members are added, how signals pass, and how a jobsite is started. Because of this, the crew should confirm the setup process with David Clark Company directly before a shift to see how its products are set up at the jobsite. Ask the company about any necessary hardware, how connections are established between headsets, and how it confirms that communication is working before a lift.
