How does it work metal wires, and pulleys?
Had a quick chat with a crane operator, using a wire for lifting. Asked what the max load he could lift. He said X amount, but if he uses a pulley, he could lift almost 2 times X.
Is this true? Is there a max to how many pulleys you can use/weight you can lift
Is the lifting curve linear or exponential?

The max will eventually be the physical limitations of the equipment. A wire rope can only take but so much load before it breaks. A crane can only lift but so much weight before it topples over. But if you ignore the basic physics of it there is no limit. I have heard of trucks using multiple snatch blocks and literally pulling the winch off the frame of their vehicles. Force multiplication is powerful.
