I was under the impression that someone got in on the ground and then made the arm go up while carrying things and at the end of the day, the person made the arm go down and went home.
But cranes are always up at night. So what do they do? How do they work?
In: Technology
so cranes are like giant robotic arms that lift stuff. they have a cab at the top where a person controls it. they dont just go up and down like you thought. they use pulleys and counterweights to be stable and lift heavy things. even at night they stay up to keep construction sites safe. nobody wants to step on a crane in the dark right?
