This review article investigates the design, development, and optimization of mechanical torque boosters based on the capstan concept in order to improve torque transmission through the frictional interaction between a rope and a drum. Analysis of design processes, operating principles, material choices, and performance metrics, including torque, speed, efficiency, and power amplification ratio, are all prioritized. Prior research and prototypes show that amplification is highly dependent on a number of variables, such as the diameter of the drum, the rope material, and the coefficient of friction. This study identifies the gaps in existing research and shows potential to improve efficiency, dependability, and compactness by combining results from simulation-based methods, analytical models, and experimental studies. The study finds that although additional material and design parameter modification might greatly improve their performance, mechanical torque boosters provide an affordable and useful substitute for industrial applications needing strong torque amplification with little input effort.
