The Isoperfect ECO system stands up because it has an automatic vertical KA Hidra loading bridge instead of the telescopic ramp, which makes it a lower cost system that involves less maintenance to run effectively. This aspect does not affect the efficiency of the whole system since the doors of the truck open inside the building achieving a significant energy saving. The loading bridge can have a fixed or a telescopic lip to better accomodate the gap between the loading bridge and the truck. Adjustment up to 500 mm.
