车辆地板与平坦行人通道之间的最小距离。对于工业车辆，必须进行特定用途的检查，以确保有足够的离地间隙，以防止车辆底部撞到行人道上，例如通过地面不平整或过渡弯道。

        Smallest distance between truck floor and an even travelway. For industrial trucks, application-specific checks must be made to ensure enough ground clearance to exclude the truck bottom bumping onto the travelway, for example through ground irregularities or transition bends.
