I ran tower cranes and other equipment for a living .
I don't think you realize the things that can go wrong while raising/lowering a human being or any load for that matter..
For instance , a gust of wind blows and that person loses his/her grip and flies off the block ( that's what the hook and cable is connected to ) , or legs/arms , body , neck were entangled in the cable .
By the way , the cable as you refer to it is called a wire rope.
These are the reasons that "riding the hook" was banned and is illegal in the U.S.
If the company owning/leasing the crane were to attempt this lowering , they would than take responsibility for that person's death/injuries.
There are just too many variables involved in lowering a human to attempt this.
This is not a load of iron or a bundle of plywood..
