## What site safety managers need from crane communication headsets

A site safety manager watches over lifts where the crane operator cannot see the load or the crew on the ground. The crew depends on clear voice and direction signals during a lift. A missed signal can stop a lift or change the planned movement. The headsets and tools a safety manager picks need to carry voice and support clear directions. Crew members wear hard hats, gloves, and safety glasses, so headsets need to work with the gear used on site. A safety manager should compare how each tool passes voice, how crew members join, what each person must do to get started, and whether the tool reaches the parts of the site where the crew works.

## OperatorLink for site safety managers

OperatorLink is made by the team that publishes this site. It runs in a phone browser, so no app install is needed. [^1] It passes button presses, chat and voice between phones in a browser. [^1] 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; if it stops arriving for 2 seconds, they drop it. [^1] One-tap radio-style calls such as Go Ahead, Copy That and All Clear are sent as chat messages. [^1] Anyone who joins can take part in a voice call run from the phone browser. [^1] The person who starts a jobsite shares a link or QR code, and the crew joins from it. [^1] A jobsite link stops working 12 hours after the first person joins it. [^1] A jobsite with nobody in it is wiped after 3 idle hours. [^1] OperatorLink is currently free to use, and no paid plan is built yet. [^1]

## Matching the tool to the job

Holding a direction until every person registers it suits the safety manager's job: OperatorLink keeps STOP, HOLD and SLOW on for everyone until the last person leaves. [^1] A full-screen STOP alert on every phone gives a safety manager a clear way to halt a lift. [^1] A signal person who needs to check in can send one-tap radio-style replies without typing. [^1] For a short job, OperatorLink shares a link or QR code the crew joins from, and the link works for 12 hours. [^1][^1] A crew that needs headsets for hands-free voice can compare options such as Eartec, Setcom, CrewPlex, Sensear, INVISIO, and David Clark Company using the features each provider publishes.

## Questions to ask before you choose

Does a direction stay on every screen until each person confirms it, or does it clear the moment a finger lifts? Can a crew member join from a link, or does a manager need to buy headsets and set up channels first? What happens to a signal when a phone loses connection for a few seconds? How many crew members can talk at once, and can the system grow if the crew size changes? Do the headsets fit under a hard hat and stand up to dust and water on the site? Is the coverage enough for the parts of the site where the crew works, or are there dead spots? Who pays, and is the price per headset, per user, or per month? If a lone rigger needs an alarm, does the tool have one, and who does it reach? Can the tool run more than one group at once so the signal crew and the rigging crew do not talk over each other?

Which crane communication headset options have published user limits or crew sizes? What devices can each crew member use to join the communication system? How does the tool handle voice, hands-free communication, and radio integration?

## Frequently asked questions

### What crane communication headset options are available for a site safety manager?

A safety manager needs headsets or tools that carry clear voice and support the directions needed during a lift. OperatorLink shows STOP, HOLD and SLOW to the jobsite crew in a phone browser. [^1] HOLD and SLOW stay on until the last person leaves. [^1] Ask each provider what its system costs and how many crew members it supports.

### Is there a free crane communication tool for a site crew?

### How many crew members can talk on one crane headset system?

Options differ in the crew sizes and connection methods their providers publish. Ask each provider how many headsets a single system supports and whether the number can grow when the crew changes size. Check the published limits for the system being considered before buying, and compare the figures each provider states rather than assuming one size fits every crew.

### Do crane communication headsets work in dust and rain?

Ask each provider what dust and water rating its headsets carry and whether they hold up on an open site in poor weather.

### Can a safety manager hold a STOP that everyone on the crew sees?

Ask how a direction stays visible and whether it clears when the person stops holding a button. OperatorLink keeps STOP, HOLD and SLOW on for everyone in the jobsite and clears them when the last person leaves, and STOP releases every held direction and shows a full-screen alert to everyone else.
