Heavy lifting by drone: when it replaces a crane and what to plan

The short answerA heavy-lift drone suits moving limited loads to places that are hard to reach, such as a roof, a slope or an area with no road. It does not replace a crane on every job. Weight, wind, route and permits decide whether it is possible.

Sometimes the problem is not the weight but the way there. A few dozen kilograms of equipment for the top of a tower, a roof with no lift or a slope with no road can mean placing a crane, opening a track or long hand-carrying. In cases like these, a heavy-lift drone is worth checking.

How much can a drone lift?

It depends on the aircraft, the batteries and the conditions. Two examples from the market, according to a distributor:

Example modelStated maximum weight
DJI FlyCart 3030 kg with two batteries, 40 kg with one
DJI FlyCart 10085 kg with two batteries, 100 kg with one

These are maximum manufacturer figures, not a commitment for a particular job, and they may vary between countries. In practice, the liftable weight depends on temperature, wind, distance and safety margin. The FlyCart 100 winch is listed with a cable of up to 30 metres, which allows a load to be lowered without landing.

What is it good for?

  • Roofs and towers. Moving equipment and materials when there is no lift or a crane is unavailable.
  • Areas with no road. Slopes, open land and remote sites.
  • Power lines and infrastructure. Pulling a pilot line and bringing equipment to poles.
  • Solar installations. Equipment for roofs and difficult ground, according to the weight of each item.

6 things you must plan

  1. Real weight. Including packaging, straps and hook. Weigh it, do not estimate.
  2. Load shape. A wide, or light and bulky, load swings in the wind.
  3. Route. Not over people, with a closed area at the lifting and lowering points.
  4. Weather. Decide in advance up to what wind you work and what happens if it is postponed.
  5. Ground crew. Who attaches, who detaches, and how they talk to the pilot.
  6. Permits. Carrying an external load is an activity to check with the Civil Aviation Authority before the job.
Important: this is not legal advice. The requirements for a particular job are checked with the Civil Aviation Authority and against the insurance documents before committing to a date.

What should you send to get an answer?

  • The weight and dimensions of each item, and how many items.
  • The lifting and lowering points, and the distance between them.
  • Who is in the area and how it can be closed.
  • The preferred date, and whether it is flexible.
