特征值表示工业车辆应对上升坡度的能力。特征值以百分比表示，代表仍然允许的上升坡度的度量。可协商的梯度在用于工业车辆的车辆专用数据表中列出，即，对于KB 30的操作（即30分钟的持续时间）为可协商的梯度，对于KB 5（即短期操作）为“最大可协商的梯度”。持续5分钟。数据进一步区分是在有载还是无载的情况下由工业车辆来决定上升斜率。

         Characteristic value expressing the ability of an industrial truck to negotiate upward slopes.. The characteristic value is expressed in percent and represents a measure of the still permissible upward slope. The negotiable gradient is listed in the truck-specific datasheet for industrial trucks, namely as negotiable gradient for an operation of KB 30, i.e. a duration of 30 minutes and as "max. negotiable gradient" for KB 5, i.e. for short-term operation with a duration of 5 minutes. The data is further differentiated as to whether the upward slope is to be negotiated by the industrial truck with or without load.
