Pig Release idea

I took a few minutes and drew this with microsoft paint. the question is; How do you release your heavy pig from the anchor while you are at the top of the pitch? This is ideal for using a counterweight haul (aka body haul). This gadget would come in two pieces. Au unintentional perk with the long thin handle on the left is as you are docking the pig to the power point, this device could lift the pig up an inch or 2, thus releaving the tention on your haul system for easier take down. This is just an idea I cooked up. Should someone else decide to mass produce these things, better talk to me first!
