One article leans towards an approach where the ICE and Electric trucks share the same chassis. In another article, there is mention of the ability to offer "equivalent trucks" between ICE and electric, which could mean anything from common chassis to equivalent run time, load capacity, or any number of other variables. To further complicate the matter, the Order Picker and Turret units have long touted themselves as being "modular", even though masts, platforms, front end attachments, seats, etc. have always been modular (interchangeable) components. As such, i'm confused about what they mean when the word "modular" is used in this context. Can anyone shed some more definitive light on this?
