Abstract

DISPOSITIVO DE LIMITACION AUTOMATICA DE LA APERTURA DE UN EQUIPO DE ELEVACION. EL BRAZO DE ARTICULACION (4) ESTA UNIDO EN UN EXTREMO CON LA TORRETA GIRATORIA (2) Y POR EL OTRO EXTREMO CON EL BRAZO TELESCOPICO EXTENSIBLE (6) FORMADO POR UN ELEMENTO TUBULAR (10) AXIALMENTE FIJO Y POR UNO O MAS ELEMENTOS TELESCOPICOS (11) QUE PUEDEN MOVERSE RESPECTO DEL PRIMER ELEMENTO. A UN LADO DEL ELEMENTO (10) ESTA DISPUESTA UNA VARILLA (12) QUE CONECTA POR MEDIO DE UN SISTEMA DE RUEDAS DENTADAS A UN INTERRUPTOR ELECTRICO (19) QUE ACTUA EN COMBINACION CON UNA PLACA (20). ESTA RECIBE UN PERFIL DE TOPE QUE REPRODUCE EL TRAZADO DE LA MAXIMA APERTURA PERMISIBLE EN LAS DIVERSAS CONDICIONES DE USO DEL EQUIPO.
