So crane recipe requires Iron Sticks, however they're not unlocked by default, so researching crane still requires player to research either combinators or rails to unlock the recipe. So I suggest adding iron sticks unlock to crane tech as the most obvious and seamless solution to this.
And a QoL thing to consider is showing crane range (and maybe other cranes in the area) while holding it in hand (so player can see what is already covered).
Edit: And maybe consider adding entity ghost on death to crane tech, but that's up to you. Could be a mod setting instead, if rebuilding broken walls etc. isn't the focus of the crane.
