The short answer

A crane crew member needs a way to send stop, hold, and slow signals to every worker while the crane moves. Clear-Com provides wired and wireless intercom systems that deliver real‑time professional communication across a range of hardware from compact partyline sets to large networked platforms [1] [1]. INVISIO develops integrated communication systems for defense and public safety professionals [2]. OperatorLink shows STOP, HOLD and SLOW on each phone and passes button presses, chat and voice in a browser, giving a software‑only signal solution [3]. The choice depends on whether crews want full‑intercom hardware, hearing protection headsets, or a browser‑based signal tool.

What Clear-Com, INVISIO is built for

Clear-Com has provided broadcast solutions worldwide since 1968 [1]. Its product line runs from compact partyline units to large‑scale networked platforms, covering broadcast production, theatre, cruise ships, festivals, corporate events, and rentals [1] [1]. The company also serves military, aerospace, and government markets with command‑and‑control communication solutions [1]. In the industrial sector, Clear-Com offers real‑time communications for marine, offshore, medical, power, oil & gas, public safety, transportation and retail environments [1]. Its Arcadia Central Station provides a scalable IP intercom platform that integrates wired and wireless stations [4]. The DX Series Wireless delivers a compact, two‑way, hands‑free system in the 2.4 GHz band [4]. FreeSpeak Wireless operates on 1.9 GHz, 2.4 GHz and 5 GHz bands [4]. Clear-Com’s wireless solutions give hands‑free, full‑duplex communication [4].

INVISIO develops integrated communication systems for defense and public safety professionals [2]. Its personal, mounted and intercom kits are based on simplicity, modularity and flexibility [2]. The personal system includes headsets, control units and cables with accessories [2]. The RA4000 headset provides ultimate hearing protection in high‑noise environments [5]. The T7 is a submersible, lightweight over‑ear headset for tactical use [2]. The X5 offers in‑ear hearing protection with natural situational awareness [2]. INVISIO also supplies tactical hubs: the V60 II for advanced users [2], the H4 compact 4‑port hub for agile missions [2], and the H6 6‑port hub for complex missions [5] [2]. The Control app lets users manage the intercom system before a mission or on the go [5].

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; if it stops arriving for 2 seconds, the other phones drop it [3]. One‑tap radio‑style calls such as Go Ahead, Copy That and All Clear are sent as chat messages [3]. Anyone who joins can take part in a voice call run from the phone browser [3].

Pricing and fees

The facts gathered for this page give no price for Clear-Com’s intercom systems, so Clear-Com’s prices are not published here. The facts also give no price for INVISIO’s headsets, hubs or systems, so INVISIO’s prices are not published here either. OperatorLink is currently free to use, and no paid plan is built yet [3]. The card fee is not published for any of the three options. Crews that expect a card fee should ask each provider before choosing.

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].

Clear-Com’s facts describe wired and wireless intercom systems, scalable IP platforms and hands‑free wireless communication, but they do not describe how a crew is added or how a jobsite is started [1] [4] [4]. INVISIO’s facts describe personal systems with headsets, control units, tactical hubs and a Control app, yet they do not explain how a crew joins or how signals pass on a jobsite [2] [5]. Crews should confirm setup steps with each provider directly before a shift.

Things to check before you choose

Does the crew need hearing‑protection headsets for high‑noise work? If so, check whether INVISIO’s RA4000, T7 or X5 headsets meet the site’s noise levels [5] [2] [2].

Does the crew need hands‑free full‑duplex communication? If so, check how Clear-Com’s wireless systems perform in the field [4].

Does the crew prefer a browser‑based signal tool with no app install? If so, verify that OperatorLink’s browser approach works on the phones the crew carries [3].

What are the total costs, and which hardware packages or software plans would be required? Prices are not published for Clear-Com or INVISIO on this page.

Which signals (STOP, HOLD, SLOW) does the crew need, and how will each tool be tested 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 [3]. If the crew needs HOLD and SLOW to stay on for everyone until the jobsite empties, OperatorLink’s sources describe that as well [3]. If the crew wants a free start with no paid plan, OperatorLink is currently free to use [3]. If the crew requires wired or wireless intercom hardware for real‑time professional communication, Clear-Com’s pages describe systems from compact partyline to large‑scale networked platforms [1] [1]. If the crew needs hearing‑protection headsets and tactical communication hubs for defense or public safety work, INVISIO’s pages describe personal systems, hubs and a Control app [2] [5]. Crews that need both signal handling and intercom hardware should check each option against both needs, because no single source covers both.

The T7 is a submersible, lightweight over‑ear headset [2], and the X5 is an in‑ear headset with natural situational awareness [2].
