Narrow Aisle unveiled its new models which look remarkably like the old ones, in a move described by managing director John Maguire as the 911 (a reference to the Porsche 911 which retains its body shape, but benefits from significant changes under the hood and in the cabin).
At the heart of the Flexi revolution is the adoption of digital technology which Maguire explained was necessary for the move to lithium-ion batteries.
"The introduction of digitally controlled motors for all key functions delivers a more integrated truck performance and results in greater reliability, higher productivity and significantly reduced operating and maintenance costs," he explained.
The innovation has also boosted the performance of the lead acid versions of the Flexi, he added.
Another benefit of the digital platform is the ability to easily add sensors, and Flexi's latest enhancement is the inclusion of proximity sensors - like automotive parking sensors. However, unlike their car equivalents, the Flexi bump sensors can actually "de-activate the truck" rather than just make a noise.
"This technology has allowed us to develop bigger and heavier trucks, like the new Narrow Aisle's Flexi ACiON that can operate safely and efficiently in aisles measuring just 1.6 m wide and can lift loads weighing up to 750 kg to heights of 14 m," he added.
