.. Getting the gear at supply courtyard

You should tilt the cart so that it can be grabbed.

It is not that easy... Tove can't reach it. She is too short. It has to be Henrik.

You need some counterweight.

Stones. Two stones. ( Other stone is stairs down and the other is other side of the sluice machinery. Only Henrik can take it.)

Put them on the cart. There is now counterweight.

And add Tove. Two stones and one Tove is more than one Henrik. Henrik can now grab the gear.
