Sovella's workbench

This is my entry to the challenge. It's a concept based on the movement of a socket wrench. I chose to dwelve into this movement rather than a crank, because I believe it is more of a natural movement for the human arm. Also I believe humans are far more familiar with this "lever" movement. We deal with it everyday, be it a door knob or a car hydraulic jack. The table has a height adjustable between 650 and 1050 mm, and it requires less than 10 kgs of force to move the maximum allowed weight (500 kgs as per instructions).
