该图显示了典型的牵引车，其额定牵引能力为6吨，即额定DBP 1200N。

以上示例说明：

（如果8％的坡度长60 m，则包括回程在内的整个循环可以每小时执行10次）。
实线所示的荷载/坡度组合可以从坡度的固定位置重新开始。
每小时允许的运输量是总行驶距离，包括回程和任何下坡坡度。
建议将制动拖车用于超过2.5吨的拖车负载以及涉及坡度的所有拖车负载。

The diagram shows a typical tow tractor which has a nominal towing capacity of 6 tonnes i.e. rated DBP 1200 N.

The example shown above illustrates:

(where the 8 % slope is 60 m long, the complete cycle, including the return journey, can be performed 10 times per hour).
Load/gradient combinations shown by full line can be restarted from stationary on the gradient.
The permissible haul per hour is the total distance travelled, including the return journey and any downhill gradients.
It is recommended that braked trailers are used for trailer loads exceeding 2.5 tonne and for all trailer loads where a gradient is involved.
