The present invention is related to the field of fixed constructions of doors, windows, shutters or rolling metal curtains and in general of stairs, whose constituent parts, support pieces or accessories, fulfill the function of fixing devices or hooks for the elements. of the extendable stairs.
ESTADO DE LA TÉCNICA STATE OF THE ART
En la actualidad hay una necesidad creciente en las empresas dedicadas a la manipulación de redes aéreas (energía eléctrica, comunicaciones, Internet, telefonía fija, televisión por cable, etc.), las cuales requieren para la realización de sus trabajos en altura, el uso de escaleras extensibles o fijas cuyas características mejoren las condiciones de seguridad y faciliten la ejecución del trabajo al operario. At present there is a growing need in companies dedicated to the manipulation of overhead networks (electrical energy, communications, Internet, fixed telephony, cable television, etc.), which require, in order to carry out their work at height, the use of of extendable or fixed ladders whose characteristics improve safety conditions and facilitate the execution of the work for the operator.
Para este tipo de trabajo en alturas en redes aéreas, se han detectado escenarios con vulnerabilidades respecto a la seguridad, entre ellos se observa la deficiente estabilidad de una escalera extensible apoyada en un poste, la inexistencia de un punto de anclaje fijo para instalar la línea de vida y garantizar un ascenso y descenso seguro durante la ejecución de trabajos en alturas con escaleras extensibles. For this type of work at heights in overhead networks, scenarios with security vulnerabilities have been detected, among them the poor stability of an extendable ladder supported on a pole, the lack of a fixed anchor point to install the line. of life and guarantee a safe ascent and descent during the execution of works in heights with extendable stairs.
Así mismo, los operarios pueden versen expuestos a fuerzas externas que pueden originar movimientos bruscos y afrontarle situaciones imprevistas durante la ejecución del trabajo en alturas, éstas situaciones pueden ser, por ejemplo, fuerzas aplicadas desde el suelo por personas o vehículos ajenos a la planificación de los trabajos donde se puede ver comprometida la estabilidad del montaje; por otro lado, los errores humanos u omisiones parciales o totales de los procedimientos de seguridad establecidos por las empresas que realizan trabajo en alturas, también son un agravante que acrecienta este problema. Likewise, operators can be exposed to external forces that can cause sudden movements and face unforeseen situations during the execution of work at heights, these situations can be, for example, forces applied from the ground by people or vehicles unrelated to the planning of works where the stability of the assembly can be compromised; On the other hand, human errors or partial or total omissions of the safety procedures established by the companies that carry out work at heights are also an aggravating factor that increases this problem.
Por tales motivos y debido a estas vulnerabilidades, se establece como un factor crítico para el proceso, asegurar adecuadamente la parte superior de la escalera a la estructura. For these reasons and due to these vulnerabilities, it is established as a critical factor for the process, to adequately secure the upper part of the ladder to the structure.
