Fixed pulleys are similar to, and are considered by many to be, first class levers. In a first class lever, the fulcrum of the lever is placed between the load (resistance) and force (effort). In a fixed pulley, this is essentially the same.
Picture a piece of rope hanging from a ceiling from one end, and with you holding the other end. A weight on a pulley is placed in the middle. Now, if you pull up on the rope, the weight rises, just like with a first class lever. Since the load is between the fulcrum (the pulley) and the effort (you pulling up), the fixed pulley acts like a first class lever.
