Apparently that one was lifted on by hand, which proved to be more trouble than it was worth. They eventually just made it a permanent attachment and removed the wings so that it could just act as an extra engine for the carrier. The small planes in this photo are Polikarpov I-5s, which weigh about 1,400 kg fully loaded, so 20-ish people could feasibly lift and move one assuming they’ve all got somewhere to stand.
It’s easy enough to see how they got the planes on the wings, but what did they do for the fuselage? Crane? Angled ramp not shown?
