Abstract

This study redesigns a Grappling Hook Guns system by integrating improvements to the projectile, pneumatic chamber-barrel, electric ascender, and body harness to enhance structural capacity and operational performance. The research combines literature review, field observation, engineering calculations, SolidWorks-based structural analysis, prototype development, and experimental testing. The redesigned chamber-barrel uses Aluminum 6061-T6 and operates at an effective working pressure of 17.01 MPa, producing a projectile velocity of 19.8 m/s and reaching an operational height of approximately 15 m. The projectile load capacity increased from 150 kg to 200 kg without permanent deformation. The modified electric ascender, incorporating pulley and transmission improvements, lifted loads up to 110 kg while improving rope movement stability. The redesigned body harness showed a safety factor of 9.2 under a 100 kg load. These results indicate that the integrated redesign improves the mechanical performance, load-bearing capability, and functional reliability of the Grappling Hook Guns system for personnel
