The smallest crane in the world is sold in China. You can buy it through the online marketplace Alibaba for just 12 thousand dollars.

The Baisway BWQY-3 crane is built on a motorcycle chassis. Not an ordinary one, of course, but a cargo tricycle like the Muravey. For this, it had to be extended to 4.8 m. This miracle weighs 1300 kg.
The crane boom is telescopic and allows lifting loads to a height of up to 18 m at a speed of 26 m/min. It is driven by a separate 15 hp electric motor. The load capacity of the Baisway BWQY-3 is three tons. There are even outriggers.

The motorcycle is equipped with a 22 hp engine and can reach 40 km/h. An open two-seater cabin is provided at the front.
To show that the Baisway BWQY-3 is not a toy, the Chinese recorded a video of its operation. It turned out to be quite impressive.
