Castor specifications way of judgment

First, to see the bearing capacity of the caster. Bearing capacity is an important factor of castor specifications, current castor altogether is divided into: light super-heavy castor castor, medium casters, heavy-duty casters, and etc. Castor is what type, can be from castor wheels and the thickness of the scaffold materials and qualitative analysis. The wheels and the thicker the stent materials, the material density is higher, the greater the firmness, the stronger the bearing capacity of natural. The bearing capacity of the caster wheel size, although there is a relatively reasonable scientific computing methods, but also basically see the specific use environment, also depends on the roughness of the ground. In general, the bearing capacity of the caster must choose more and more, to ensure the safety in the concrete use of can fully use. Second, look at the size of the caster. In general, the larger the caster wheel size to promote the energy saving, the more suitable environment. Size small, time rate is relatively low, also calls for more clean and tidy environment, can't have too much stuff on the ground. At the same time, the bigger the caster wheel size accuracy is not operation, the smaller the size large accuracy of operation. For the choice of the caster wheel size, in China's big supermarket cart, for example, most of the diameter of 4 - 5 'castor. Different size of caster and the current market, from the smallest 1 to 10 inches, a larger will be made out with application need. In usually use life, diameter of 3 inches below the castor can be meet. / news_175。
