Abstract

LOS EQUIPOS COMPRENDEN UNA PLACA INFERIOR (24) PERFORADA POR ABERTURAS DE SALIDA DEL REFRIGERANTE, UNA PLACA SUPERIOR (26), UNAS COLUMNAS PUNTALES (28) QUE UNEN LAS PLACAS Y LAS GUIAS DE RACIMO DESTINADAS A LOS RACIMOS DE MANDO. ALGUNAS AL MENOS DE LAS GUIAS TIENEN UN TRAMO SUPERIOR (30) QUE HACE SALIENTE POR ENCIMA DE LA PLACA SUPERIOR (26) Y UN TRAMO INFERIOR (32) QUE SE EXTIENDE ENTRE LAS PLACAS (24) Y (26). EL TRAMO INFERIOR (32) INCLUYE UNA PLACA (40) DE APOYO SOBRE UN ASIENTO TRONCOCONICO SOLIDARIO A LA PLACA INFERIOR (24) Y ESTA SOMETIDO A LA ACCION DE MEDIOS ELASTICOS (78). LOS TRAMOS (30) Y (32) DE CADA GUIA CONSTITUYEN UN ARTICULO MONOLITICO INSERTABLE DENTRO DE UNA COLUMNA (28) RESPECTIVA. LA GUIA COMPRENDE ADEMAS UN CAPOT (76) DE RECEPCION DE LOS TRAMOS SUPERIORES (30), FIJADO A LA PLACA SUPERIOR (26''), SOBRE EL CUAL TOMAN APOYO LOS MEDIOS ELASTICOS (78).
