Google "3 ring release". If you don't mind doing some sewing you can DIY i t, it's cheap, scales to just about any size, and if the rings are sized ri ght it's dead reliable.
For another pennytech option, sounds like you have access to a good supply of scrap vehicles--use a truck axle, wheel, and brake (make sure that the a xle is rated for the load you're dropping). Secure the axle to your lift, rig hydraulics to apply the brake, wrap your lift cable around the wheel, h ook your load to the cable (or strap) set the brake, lift the whole shebang , and release the brake (make sure you have enough hose on the release valv e to get to a safe distance).
