The Integro E is the only purpose built vehicle in the world designed as an ambulance from the ground up. All other ambulances are vehicle conversions that originate as a commercial chassis-cab or van, which are then retrofitted with hardware and equipment to be suitable for healthcare use.

The Integro-E chassis is made of 4003 Stainless Steel that is manufactured with a small amount of chrome and carbon making it magnetic and guaranteed for 100 years against corrosion. It is formed from a 1.5 mm sheet that is folded into double “C” sections with a height of 295mm, plus an additional vertical section making it three verticals with eight 90-degree bends per chassis rail giving a world-leading torsional rigidity.

The chassis was originally conceived as a three-axle design with all the vehicles batteries carried within it. It has now been developed so the rear chassis section incorporating the rear axle is now detachable as an integrated, non-articulated trailer. 25% of the vehicles batteries are now located in this trailer unit. The idea being that you can quickly and easily swap a depleted trailer for a fully charged one to eliminate vehicle down time.

The trailer / main chassis features a double “V” (male / female) shape for ease of attachment. The trailer is hydraulically actuated. The trailer is ejected from the ambulance by the press of a button. The locking pin is then removed by the press of another button and the depleted trailer is left to be recharged. The ambulance is then reversed onto a fully charged trailer and the procedure is reversed and the vehicle can be driven away fully charged in a matter of minutes.
