The short answer

A crane crew member needs to pass voice and 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 browser ^[5]. ESChat's page describes group push-to-talk calling with groups of up to 3,000 members ^[2]. Zello's page says it offers Zello free for first responders ^[4]. Which one fits depends on whether the crew needs signal handling, large group calls, or a plan for first responders. The cited sources say nothing about signals on a jobsite for either rival, so a crew with that need should check it directly.

What ESChat, Zello is built for

The facts gathered for this page describe a few things about ESChat and Zello, all taken from their own pages. ESChat supports group push-to-talk calling with groups of up to 3,000 members ^[2]. ESChat's page describes it as FedRAMP Certified, GovRAMP Authorized, TX-RAMP Certified and FirstNet Certified ^[2]. Commercial customers receive a 10% discount on annual cloud hosted service ^[1]. Zello's page says it offers Zello free for first responders ^[4], and Zello Work subscriptions can be changed or cancelled any time without penalty ^[3]. Those facts do not describe how either tool handles signals, stops or hand signals on a jobsite, so this page does not say what they do for those jobs. A crew that wants a first-responder plan or a discount should check how it applies to its own account before relying on it.

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 ^[5]. A STOP releases every held direction on every phone and shows a full-screen alert to everyone else ^[5]. HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves ^[5]. 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 ^[5]. One-tap messages such as Go Ahead, Copy That and All Clear are sent as chat ^[5]. Anyone who joins can take part in a voice call run from the phone browser ^[5].

Pricing and fees

Prices for ESChat and Zello are set out in the table, where each price carries its source. ESChat's commercial customers receive a 10% discount on annual cloud hosted service ^[1]. Zello Work costs $8.00 per user per month, or $6.80 with an annual subscription ^[3], and subscriptions can be changed or cancelled any time without penalty ^[3]. OperatorLink is currently free to use, and no paid plan is built yet ^[5]. The card fee is not published for either option. 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 ^[5]. The person who starts a jobsite shares a link or QR code, and the crew joins from it ^[5]. Phones can add the app to their home screen as a standalone app ^[5]. A jobsite link stops working 12 hours after the first person joins ^[5], and a jobsite with nobody in it is wiped after 3 idle hours ^[5]. Button presses, chat and voice pass between phones in the browser ^[5]. The facts gathered for ESChat and Zello do not describe how a crew is added to either tool, how its signals pass, or how a jobsite is started, so the crew should confirm those steps with each provider directly before a shift.

Things to check before you choose

Does your crew use push-to-talk voice, and how large are the groups you need? ESChat's source describes groups of up to 3,000 members ^[2], so check whether the tool you pick covers your shift size. Is part of the crew made of first responders, and does the free claim apply to their accounts ^[4]? Does a jobsite link that stops working 12 hours after the first person joins suit your shifts ^[5]? Which signals does the crew need on a jobsite, and how will you test that each tool passes them before a lift?

How to choose

If the crew needs a stop that reaches every phone, OperatorLink's sources describe a STOP that releases every held direction and shows a full-screen alert to everyone else ^[5]. If the crew needs HOLD and SLOW to stay on for everyone until the jobsite empties, OperatorLink's sources describe that as well ^[5]. If the crew needs large group push-to-talk voice, ESChat's page describes groups of up to 3,000 members ^[2]. If the crew is made of first responders, Zello's page says it offers Zello free for them ^[4]. A crew that needs both signal handling and a rival's voice plan should check both needs, because no single source here covers both.
