4.3  Transporte y manipulación

• 7

Use las argollas de izado para izar un ERD sin motor eléctrico.

• 7

Las unidades iSave equipadas con motor eléctrico (horizontal)

no deben izarse mediante argollas de izado. 

Las unidades iSave con motor 

(horizontal) deben manipularse sujetando la unidad con dos eslingas. Una eslinga debe sujetar el motor eléctrico; la otra debe sujetar la 

unidad iSave. • 

8

Asegúrese de que la unidad/carga esté equilibrada antes de izarla. El centro de gravedad podría desplazarse.

• 8

Algunos motores y bombas poseen argollas de izado específicas.

• 8

¡No use conexiones/toberas para las operaciones de izado!

• 8

Use siempre dos eslingas.

• 11

El elemento 5.1 muestra una vista en sección del iSave

• 11

El iSave consta de un intercambiador de presión isobárgico giratorio y un bomba de desplazamiento, también llamada bomba 

de refuerzo. La velocidad de rotación del intercambiador de presión y la bomba es exactamente la misma, ya que son acciona-

das por el mismo motor eléctrico.
