Treehouse Pulley

The Treehouse Pulley is a machine that Edd built to lift Ed and Eddy to the ground floor of the treehouse that they were building. Like a previous pulley invention, the pulley was initially hand-operated. However, after a few mishaps involving Ed (and in one instance Eddy) falling over the side, a motor was hooked up to the pulley in order to get them back into the treehouse more efficiently. After the treehouse was built, however, the pulley was taken down, as steps had been installed into the trunk of the tree.
