You are in the car wreck. I think the way of the canopy top gets you to the Crane.
Yes, it is attached to the Hood. It is hold open with the red lever.
It can't be just removed. Maybe you could shoot it down?
With the fork, of course!
You get the fork from the French Door. It opens with the Crank you reach from the Left Window.
Go to the Pipe, stick the fork into the Horn and use the Horn to shoot!
