La gr\u00faa se desplaza longitudinalmente a lo largo de la v\u00eda, mientras que el puente se mueve a lo ancho del taller, lo que permite que el gancho alcance diferentes posiciones de elevaci\u00f3n.<\/p>\n<p>Es importante comprender que <strong>La envergadura de la gr\u00faa no es igual al ancho del taller<\/strong>. Las columnas del edificio, la ubicaci\u00f3n de las v\u00edas de rodadura, la disposici\u00f3n de los equipos y los espacios libres requeridos pueden influir en la luz final.
