工业车辆的设计原理具有高承载能力，并且由于车轮直径较大，还适合在不平坦的行进路线上用于户外。与三轮构造相比，室内使用的缺点是轴距长，尺寸较大，因此，转弯半径较大且过道宽度较宽。

        Design principle for industrial trucks which features high carrying capacities and is also suited for outdoor use on uneven travelways because of the large wheel diameters. Disadvantages for indoor-use is the long wheelbase, larger dimension and, thus, a higher turning radius and wider width of aisle as compared to three-wheel construction.
