Block and Tackle Pulley System - Manual Lifting Mechanism Diagram #181773 (License: Personal Use)

This black-and-white technical illustration shows a traditional block and tackle setup with two movable pulleys and one fixed pulley, connected by a continuous rope. A human hand applies force to the free end of the rope, lifting a staved wooden barrel suspended from the lower hook. The design emphasizes mechanical advantage, reducing required effort by distributing load across multiple rope segments.
