Improvements to a pulley is disclosed. The rope is threaded through the self-locking pulley in the desired direction. At some places, the threading passes the rope or strap in opposing directions to cause a binding and prevent free movement of the rope or strap in one direction. There are no one-way clutches or self-locking teeth to lock movement in a particular direction. A first part it secured to a spinning mount or ceiling so a user can walk around a suspended self-locking pulley and pull the rope or strap from any direction. The second part can pivot and move up-and-down on the first piece. A threaded member alters a frictional lock between the at least two interconnecting pieces. The interaction of the at least two pieces allows for lifting, locking and lowering of a load on the rope or strap.
