Device to hold and release heavy weights?
(OP)
I'm trying to build a test setup that lifts, holds, and then drops a heavy weight. A user would manually hook, latch, or somehow fasten a heavy weight (~100 lbs) to a frame, a motor would pull this weight up, and then the user would click a button on a screen and some mechanism would release the holding mechanism and allow the weight to free fall. Ideally it would be some electromechanical mechanism that would take some digital or analog input. The problem I've run into is that I'm not sure what to search for. I know there are mechanisms out there that will allow me to do this, but if someone could point me in the correct direction, I'd appreciate it. The system could be purely electromechanical, pneumatic, hydraulic, pretty much anything. The one restriction would probably be the actual actuating device would have to fit on a 1'x1 platform and be less than a couple inches tall. Any ideas?
Thanks,

2) what material is the weight?
NX 7.5.5.4 with Teamcenter 8 on win7 64
Intel Xeon @3.2GHz
8GB RAM
Nvidia Quadro 2000

Try a rotary latch such as those made by Eberhard or Southco. A fairly small latch can hold 750lb and have a trigger arm that relases is. They are fairly inexpensive. Of course, I'm sure they are not rated for overhead load applications becuase of safety concerns, but with proper guarding and safety precautions they should work. Here is a link to the Southco site:

Heck just a 2x4 frame with a rope, a pulley setup, and a quick release latch will get the job done..
Use multiple pulleys to decrease the user effort if needed.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

I'm sure you could rig up a solenoid to pull the cable out.
