Lifting and carrying loads by drone: construction sites, roofs, hard-to-reach places — rules, price

Getting three hundred kilos of tiles onto a town-centre roof, supplying parts to an antenna on a pylon, provisioning a mountain-hut worksite or replacing a beacon on a cliff face: between what a person can carry and what justifies a mobile crane or a helicopter, there is a logistical no-man's-land that cargo drones are moving into. The promise is not to replace the tower crane: it is to eliminate the hoisting scaffold erected for a day, the crane truck blocking the street, the disproportionate helicopter rotation. Here is what these machines can really carry in 2026, the regulatory framework they fly under, the use cases where the equation works, and observed prices.

What a cargo drone really carries in 2026

Three classes of machine structure the offer. Ordinary work multirotors carry 5 to 30 kg per rotation: tool packages, mortars and consumables, small repeated supplies. Heavy cargo drones, often derived from agricultural spraying platforms or purpose-built for lifting, carry 30 to 100 kg depending on model and conditions: tiles and roofing materials, antenna equipment, timber and bags to landlocked sites. Beyond that, a few experimental machines and unmanned helicopters are preparing the hundred-kilo-plus segment, but most of the French market currently plays below that threshold. Productivity comes from the shuttle pattern: two-to-five-minute rotations, chained, move several tonnes in a day.

The rise of light aerial logistics is an established research object: the review by Otto, Agatz, Campbell, Golden and Pesch published in 2018 in Networks surveys civil drone applications and structures the optimisation problems of load transport — rotations, pick-up points, combination with ground means (see the study on Google Scholar). The practical conclusion holds for a worksite as for delivery: the drone wins when the load can be split and ground access is expensive.

The regulatory framework: specific category, exclusion zone, slung load

Professional lifting almost always exits the open category: the masses involved, worksite overflight, load release or placement. It operates in the specific category, on the basis of a risk assessment (SORA) or an adapted scenario, with an operations file describing machine, zone, winching or slinging procedures and failure cases — the administrative machinery we detail in our BVLOS, STS and SORA guide. On the ground the golden rule is as physical as it is legal: nobody under the load, ever — the lift plan defines a flight corridor and a ground exclusion zone, coordinated with the site.

The site's own rules add on: prevention plan, safety coordination, possibly a municipal order if the corridor skirts public space. Concretely, a drone lift is prepared like a small crane operation: reconnaissance, fixing of pick-up points, briefing of the hooking and receiving crews. The drone that documents cranes and lifting structures and the one that carries the load belong, in fact, to the same ecosystem of site skills.

The use cases where the equation works

Roofing and façade work on constrained sites: supplying tiles, zinc or mortar to a town-centre roof without a material hoist or a closed street — the fastest-growing case among tradespeople. Telecoms and energy: hoisting tools and parts onto pylons and technical roof terraces, pulling stringing lines on power lines. Mountains and landlocked sites: provisioning a hut worksite, an avalanche-defence structure or a beacon, where the alternative is helicopter slinging — billed by the minute and subject to its own availability. Events and industry: placing equipment on tall structures without a lift. In all these cases the calculation is the same: the drone does not beat the crane on tonnage, it beats it on mobilisation — no ground footprint, no blocked roadway, deployment in hours.

Conversely, the equation fails for heavy monolithic loads (frames, machines), long-distance shuttles in dense areas, or sites where a crane is present anyway. A serious provider says so upfront — and then proposes the right solution, not their own. For last-mile logistics and its French trials, see our drone delivery in France guide.

The sizing item is preparation: a safe flight corridor and briefed crews make the shuttle's productivity. Request a quote stating the load's nature and how it can be split, the pick-up and set-down points, and the site's surroundings — feasibility turns on those three elements.

Frequently asked questions

Can a drone replace the mobile crane on an ordinary site?

No, and that is not its ground: a mobile crane lifts tonnes in one piece. The drone wins when the load splits into rotations of a few dozen kilos and ground access is expensive — a street to close, a hoisting scaffold to erect, a landlocked site. It is one more tool in the lifting palette, not a universal substitute.

Who is liable during a drone lift?

The drone operator answers for the aircraft and its load within their operations file and insurance; the worksite remains governed by its own rules (prevention plan, safety coordination, exclusion zone). The precise split is set in the lift plan, as for a crane operation — a document to require from the provider.
