World Scan Project has successfully conducted a flight test with a prototype flying crane called the Sky Crane. The company is working on the development of sky cranes as part of the development of future construction infrastructure.
A sky crane is a crane that can literally fly through the air. It is operated by humans like a regular crane, but instead of moving on the ground, it moves in the air.
During flight tests, the prototype levitated to a height of 1 meter above the ground. A sky crane with a weight of 70 kg carried a load weighing 80 kg while maintaining its flight altitude for 7 minutes while successfully moving 5 to 7 meters forward, backward, left and right.
