Esto sucede cuando el operador de la gr\u00faa deja de levantar o bajar la carga, pero esta contin\u00faa descendiendo, a menudo m\u00e1s all\u00e1 del l\u00edmite permitido de v\/100 (donde v es la velocidad de elevaci\u00f3n nominal). Esto plantea graves riesgos si la carga se desliza hasta el suelo. Otro problema ocurre cuando el freno no se libera, lo que restringe el mecanismo de elevaci\u00f3n, impidiendo que la gr\u00faa alcance su capacidad de elevaci\u00f3n total.<\/p>\n\n\n\n<p><strong>Causas de un frenado incompleto<\/strong><\/p>\n\n\n\n<p>Un frenado incompleto, que permite que la carga se deslice, puede deberse a varios factores:<\/p>\n\n\n\n<ul>\n<li>Desgaste: el uso frecuente puede provocar el desgaste de componentes como pasadores, orificios y pastillas de freno, lo que genera variaciones en la posici\u00f3n del brazo del freno y una reducci\u00f3n del par de frenado.<\/li>\n\n\n\n<li>Problemas con los resortes: Los resortes principales d\u00e9biles o mal ajustados reducen la fuerza de frenado, a menudo debido a la mala calidad del material o a la fatiga.<\/li>\n\n\n\n<li>Desalineaci\u00f3n: La desalineaci\u00f3n radial de la rueda de freno puede provocar excentricidad, lo que provoca una reducci\u00f3n en la eficiencia de frenado.<\/li>\n\n\n\n<li>Espacio desigual entre las pastillas: el contacto desigual entre las pastillas de freno y la rueda de freno reduce el torque, a menudo debido a imprecisiones en la instalaci\u00f3n o pernos flojos.<\/li>\n\n\n\n<li>Frenos de carrera larga obstruidos: el material de soporte debajo del contrapeso puede reducir el torque de frenado.<\/li>\n<\/ul>\n\n\n\n<p><strong>Soluciones para el frenado incompleto<\/strong><\/p>\n\n\n\n<p>Para restablecer un frenado confiable, se recomiendan los siguientes pasos:<\/p>\n\n\n\n<ul>\n<li>Reemplace los componentes de freno desgastados y elimine cualquier obstrucci\u00f3n.<\/li>\n\n\n\n<li>Limpie la rueda y las pastillas de freno con queroseno o gasolina para eliminar los contaminantes.<\/li>\n\n\n\n<li>Vuelva a alinear o reemplace las ruedas de freno desalineadas.<\/li>\n\n\n\n<li>Ajuste los tornillos y los resortes auxiliares para lograr una holgura uniforme entre las pastillas.<\/li>\n\n\n\n<li>Vuelva a instalar los frenos con precisi\u00f3n para garantizar una alineaci\u00f3n adecuada y elimine cualquier soporte adicional debajo de los contrapesos.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\"

del electroim\u00e1n: una bobina desconectada detiene el im\u00e1n, lo que impide la liberaci\u00f3n del freno y produce un sonido fuerte en el motor.<\/li>\n\n\n\n<li>Varillas de freno dobladas: Las varillas desalineadas pueden obstruir el movimiento, provocando que el freno permanezca cerrado.<\/li>\n\n\n\n<li>Obstrucciones mec\u00e1nicas: Los componentes del mecanismo de freno pueden atascarse,
