Handheld two-way radios for construction sites where mobile signal is unreliable. Licence-free and licensed options, with ATEX models available, plus earpieces, remote speaker microphones and chest packs. Hands-free tower crane radios pair well with tower crane cameras; see all construction site radio equipment.
Licence-free radios work out of the box but share a small number of channels with everyone else nearby, which on a busy site means interference. Licensed radios use allocated frequencies, so the channel is yours. On a congested site or where communication is safety-critical, that difference matters more than the handset specification.
Published range figures assume open ground. Steel, concrete, tower structures and basements all cut it substantially. Where coverage has to reach below ground or through a structure, plan for a repeater rather than a more powerful handset.
Shift length dictates battery capacity and whether spares or a multi-way charger are needed. Earpieces, remote speaker microphones and hard hat mounts affect whether the radio actually gets used properly in noise and PPE.
Licence-free radios need none but share channels with other users nearby. Licensed radios use allocated frequencies and avoid that, which matters on busy or noise-critical sites.
Far less than the published figure in a built environment. Steel and concrete cut range considerably, so plan around the structure rather than the distance.
Yes, and dedicated channels for lifting operations are common practice. Keep lifting communication separate from general site traffic.
