SkyLifters are solar-electric air-cranes that help customers build big infrastructure projects by overcoming the limitations of land-crane access and helicopter payload weights.
SkyLifter air cranes are designed to vertically lift payloads up to 25 tonnes. This is beyond the technical limits of the largest helicopters.
The payload hook is suspended permanently in the sky using an aerostat, which also supports the entire mass of the aircraft. The hook position is controlled using a combination of the winches and propulsion.
The SkyLifter hook is supported from above, not below as with land-cranes. The design of the system allows us to achieve hook heights of over 300 metres.
As the hook moves horizontally, the vertical support remains constant. Therefore the maximum payload can be carried across the hook’s entire reach.
SkyLifters fly from job to job, so they can do work in locations that would be challenging for land cranes.
Plus this avoids potential disruption and environmental impact on the land access routes.
