THE DESIGN DRIVE MOTOR SYSTEM ON ASCENDER GRAPPLING HOOK GUNS

Abstract

The grappling hook gun provides KOPASKA with a major advantage in evacuation or reconnaissance routes in
hard-to-reach areas, allowing the acquisition of advantageous tactical positions in combat, as well as the utilization
of vertical dimensions in military operations. Nonetheless, challenges arise in electric control and ascender
systems that still rely on members' physical exertion, which limits the efficiency and mobility of their operations in
complex maritime environments. Therefore, this study focuses on improving the system to improve the
performance and operational effectiveness of KOPASKA. In overcoming this problem, this research uses a design
based approach to develop more sophisticated solutions. First, in terms of the control system, the study used the
6pin 3 position Toggle Switch to redesign the controls on the grappling hook gun. This toggle switch allows work
orders to be received without having to press buttons continuously, increasing the efficiency of using this weapon.
Secondly, in optimizing the ascender, the study used a 2500Lb ATV Winch motor with 12VDC power and a ratio
of 1:10. This motor is proven to be efficient and has enough lift to handle loads weighing 1133 Kg, providing a
reliable solution to the lifting power problem of grappling hook guns. Finally, to ensure optimal power availability,
this study applied a 12 VDC 7.0 Ah battery accu on the ascender tool. With a measured power consumption of
88.8 W per operation, the battery provides efficient usability, enabling up to five operations on a single charge.
Thus, these solutions contribute positively to KOPASKA's mobility and performance in carrying out their tasks in
a dynamic and diverse maritime environment.
