ABSTRACT
This research article arises from the project
modified pelvic chair with brake support
device for descent, this project is based on the
experiences of contingencies presented in the
first man when descending in the Air Assault
tower of the National Army of Colombia,
seeking to reduce the risk of accident of the
user, implementing a braking device that
consists in the adaptation of a carabiner
located in a specific point (lateral part of the
left or right leg) of the pelvic chair, being a
fixed point with greater adaptability and
anchorage security, allowing to continue with
the tasks that are being performed, giving
orientation and control to the rope, avoiding
knots due to oscillation when releasing the
brake rope.
Keywords: Descent, support device, national
army, pelvic chair.

RESUMEN
El presente artículo de investigación surge del
proyecto silla pélvica modificada con
dispositivo de apoyo al freno para descenso,
este proyecto se realiza con base en las
experiencias de contingencias presentadas en
el primer hombre al momento de descender en
la torre de Asalto Aéreo del Ejército Nacional
de Colombia, buscando reducir el riesgo de
accidentalidad del usuario, implementando un
dispositivo de freno que consiste en la
adaptación de un mosquetón ubicado en un
punto específico (parte lateral pierna izquierda
o derecha) de la silla pélvica, siendo un punto
fijo con mayor adaptabilidad y seguridad de
anclaje, permitiendo continuar con las tareas
que estén realizando, dando una orientación y
control a la cuerda, evitando nudos por
oscilación al soltar la cuerda de freno.
Palabras clave: Descenso, dispositivo de
apoyo, ejército nacional, silla pélvica.
Introduction
The Air Assault School trains officers, non-commissioned officers and professional
soldiers of the Colombian Armed Forces in the planning, development and execution
of air assault operations with emphasis on jungle, combining strategic speed with the
tactical mobility of air elements. As a specialty, they have the maneuvers of insertion
and extraction of personnel in the most remote and jungle areas of Colombia. This
implies the descent from helicopters by means of ropes, which generates a risk for the
personnel who descend, especially for the first man, for not having the support of the
rope master who is on the ground.
The Air Assault School of the Colombian Armed Forces seeks to specialize military
personnel in the highest tower in South America, so that the user socializes with the
tower and loses fear, with the above, at the time of certification in aircraft through a
