额定容量是物料搬运车辆（牵引车除外）的量度。它规定了如果遵守车辆的所有安全条件，则可以由车辆安全运输的货物的重量。
重要的是要知道额定容量和实际容量之间的差异。

• • 额定容量

-在卡车的标准起升高度和规定的（标准）负荷中心确定。

• •实际容量

-由卡车站在倾斜平台上确定，并显示在各种提升高度以及各种载荷中心下的实际载重量。实际容量还受到叉车各种附件使用的影响。
必须在叉车驾驶员座椅附近的图表中显示在各种提升高度和载荷中心处的剩余实际容量，以便驾驶员得到通知。
应当知道，给出的实际容量仅适用于标准驾驶条件-即在水平地板上驾驶，降低负载驾驶，在车辆站立时举升。
如果卡车配备了附件，则必须注意容量和负载中心的变化。

The Rated Capacity is a measure for Material Handling Trucks (with the exception of tow tractors). It states the weight of the load that can be transported safely by the truck if all the safety conditions for the truck are adhered to.
It is important to know the difference between the Rated Capacity and the Actual Capacity.

• • Rated Capacity

- is determined at standard lifting height for the truck and at stated (standard) load centre of the load.

• • Actual Capacity

- is determined with the truck standing on a tilting platform and shows the actual capacity at various lifting heights as well as with various load centres. The Actual Capacity is further influenced by the use of various attachments for the lift truck.
The remaining Actual Capacity at various lifting heights and load centres has to be shown by a diagram near the drivers seat of the forklift truck so that the driver is informed.
It should be known that the Actual Capacities given are for standard driving conditions only - i.e. driving on level floors, driving with load lowered, lifting with truck standing.
If trucks are equipped with attachments, the changed capacities and load centres have to be observed.
