Technical Stuff

Well now I´m going to start explaining the Technical Stuff of the crane.

The Crane

In the crane we used a crank rod mechanism (sistema de biela manivela) to move the crane. We needed a worm gear connected to a cable that goes to the top part of the crane to move the hook. Later we applied a tweezers to catch more easily the objects that the crane have to pick up.

The Catapult

In the catapult we had to use a few gears to hook the part that moves to the part that was fixed where we applied the force in the crank rod mechanism to move it. Also we put to cables one tense and other no so when it moves they change.

The Assault Ladder

 The Assault Ladder is a third class lever. In the Assault Ladder we also use a crank rod mechanism for raise the assault ladder as high as possible. To do this we had to put a worm gear mechanism to move up and down the gears were very big so we have to move the crank rod mechanism a lot to move a little bit.

The Wings

The wings have no lever. We need a few things to build it. there weren´t gears, there were only two cables join to a bar of metal that goes up and down to make it fly (like birds).
