Theridion grallator, also known as the Hawaiian happy-face spider, is a spider in the family Theridiidae that resides on the Hawaiian Islands.

I've been working at this for days now and every time I think I've found a solution I then work out that there's a flaw in my plan and I wouldn't be able to achieve my intended result.

Basically, there is a fixed platform. On top of the platform at one end is a a fixed vertical wall. On the platform beside the wall there is a block. At the other end of the platform is a hook below the platform. What is the simplest way to get the block to rise by placing weight on the hook, without altering the block's orientation (must remain upright, no tilting)? What kind of pivot mechanism can be used to do this?

Here is a diagram of the problem to make it clearer.

Sorry if you already understand the reason cache exists and how it works, but for those who don't:

When you visit a website like the main page of YouTube, your browser has to temporarily download and store any videos displayed on that screen in an area of your hard drive called the cache. This is so when you visit that website again in the next few days, it loads a lot faster than the first time, because the data it needs is already stored on your hard drive.

When Adobe Flash Player and Flashpoint saved videos and games this way, they would be programmed to self-destruct in a few days. But then it was discovered that if your computer shut down in an unconventional way, like through a power outage or holding down the power button, or if through glitch or virus your computer lacked the file needed to tell your hard drive to delete the cache files after a few days, often the videos and games would take up permanent residence in your cache.

People began searching their caches on old hard drives and stumbling across lost media. And now you can too, even if you know nothing about where your cache is or how to search it.

Youtuber SindexMon has exploited that anomaly through open source software he has created that scans your hard drive frame by frame for over 500 pre-programmed lost media titles. You can check out the video he has made about how this all came about or download the app he created, Decache, here.
