Concept
The ongoing construction boom has far-reaching consequences. In order to build new, it is often necessary to demolish. Not only harmful substances from past decades complicate the job, but also the separation of raw materials. Where the wrecking ball was often used in the past, today a closer look is taken.
This makes it all the more important to simplify this process and thus guarantee separation by type - starting with old nails.
There are several aspects to consider here. First, the nail must be lifted a little from the corresponding component so that the head of the nail can be grasped. The force required to pull out the nail should then not be too great and it should be prevented from being catapulted through the air just before it comes completely out of the wood, thus endangering people.

Implementation
Lift up uses several innovative techniques in the manufacture and construction of the tool. The entire mold can be 3d printed from one plastic in one pass. This saves material, time and is recycling-friendly, as no separation of raw materials has to take place.
All Lift up joints are made of highly resistant film hinges, which minimize the play in the mechanism compared to conventional bearings, while ensuring economical production.
To remove a nail from a beam, the Lift up's pincer mechanism grips the nail in the first step. By pushing the lever further back, the nail is then pulled out a little. The tool can then be repositioned by moving the lever forward, which opens the pliers and allows the tool to be reattached to the bottom of the nail.
