The Flexi truck is widely used in Europe and it is growing as a choice for customers. I have experience as both a customer and a trainer with these trucks. I found as a customer the equipment appears as great value for money on paper but when in practical operation our KPI and order picking times were seriously affected. The trucks should not be the only choice for a user as they are cumbersome when compared to other designs. As a trainer and safety provider I find these trucks dangerous and have yet to be won over to another view. It is a truck which is both a counterbalance and a reach truck. I am sure you aware the slight disorientation of operators when 'jumping' from one truck type to another but this is continual with the Flexi(Bendi). Drivers have difficulty in coordinating activities, even experienced operators. another point is that when the truck moves into a position in a narrow aisle I am unhappy with the weight vs counterweight movement as I believe that the stability triangle is compromised. If you need to see some videos of the trucks in operation they are available on the Bendi website.
I hope this helps.
Best of luck.
