I'm not sure if you read my earlier post but I'm making a home amusement park.
My current project is a kiddie drop tower. It'll be about 12 feet tall used a from a wooden ladder connected to a sturdy swingset.
I plan on using a hoister/winch to lift the "car" up. My question is..if its brought to the top of the "tower" on a winch, can you have it just become "lose and it'll drop still connected to the winch, or do I have to find a way that the car will unhook from the winch?
I plan on using two bungee cords plus two pieces of sturdy rope to use as brakes. Basically once the car is brought to the top it'll fall and the bungee cords will be the right length to stop it at the bottom. My problem is if I need it to unhook at the top from the winch.
Hey! You should read the "The Great Brain" series. It's a series of childrens books about a kid growing up in Utah around the turn of the century. In a chapter in one of the books, he builds his own Chute the Chutes from the top of the barn.
In short, he makes a bundle of money from all the kids who wants to ride the thing...which ended up being just enough to pay for the doctor bills of a kid who busted his arm when things went ary.
Good luck! Be safe!

Ok, I think I may have a solution for you. I am making a "launch machine" which is pulled back by a winch, then when the whinch releases the car zooms in the opposite direction. (it is a tad hard to explain)
To make the winch unhook from the car I am using a system almost identical to a typical boomerang coaster. It is a very simple and just about failsafe system. There are two pieces to the winch separated by two large springs. When the rear on the whinch gets stopped the springs compress causing the arm to lift up unhoking from the car. Errr, I'm trying to think of a better way to describe this. Well, maybe someone *cough*Dave*cough* could explain this much better than I.
In the event of a bungee break, it would probably be safer just to let it hit the soft dirt rather than jerk to a stop by a rope. Dirt can compress a lot under force where as a rope would stop it instantly.

If one bungy cord breaks, then the seat falls to one side, the person falls out that side, sticks their hand out to stop their fall and breaks their wrist. Not to mention the whiplash from when the cord breaks. Do whatever makes you happy, but I'd leave the ride manufacturing to the pros.
I would love to do that to my kitties. My long-haired tabby cat, Chessie, would freak out. He's afraid of the outside world! ------------------ My mind works in strange ways. Yeah with a chain driven lift hill and gravity.
