Thanks in advance.

Hello kwakers,Nick, idris, numi, Rodger and all,
I believe this worker may actually be riveting the axle holding the hook on the 13c Thames Wreck Truck.
The models looks to be almost complete and making their way to the station ready to be trim detailed before being put into a tray prior to being boxed. I would think the hook assembly would have been the last assembly type task prior to boxing.
I would think this machine has a pre-set travel or stroke subject to the length of the axle, so one hand with the fingers are holding the hook to apply pressure to stop axle falling out and the other hand holding the model.
This type of machine can then be operated with a foot operated switch to activate tool. If you look closely at the video you can see her leg move at the same time the lower part rises. The jig in this case would be designed to suit the correct seating of the crane jib.
The amount of travel could also be determined by a bed or jig holding a component and varied accordingly for other tasks.
She does it quickly, but by the look on her face has been told she must work faster.
Footnote
Usually machines like this are guarded to prevent fingers, hand or clothing getting caught as can be seen in another clip where a spare tyre is being riveted in place. In this case the actual tool may be guarded but not visible to my eyes.
