The Integro-E is the only vehicle in the world designed as an ambulance from the ground up. All other ambulances are vehicle conversions that originate as a chassis-cab or van, which is retrofitted with hardware and equipment to be suitable for healthcare use.
The 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 has always been a three-axle design, with the rear chassis now detachable as an integrated, non-articulated trailer. The double “V” (male / female) is hydraulically actuated to remove the trailer by pressing button number 2, pushing the ambulance off the trailer, then button number 3 is to remove the locking pin. You then back onto another charged trailer and reverse the procedure. You can be 33 degrees off a straight line because the double “V” is self-locating / aligning. The number three button hydraulically presses the locking pin in, then button number 2 pulls the trailer into its lock position. Button number 1 raises and lowers the hydraulic-operated tailgate. The whole procedure takes 4.1 minutes.
