Castor should how to choose and buy? Follow the below small make up look together! There are various casters, medical casters, industrial casters, and so on. In the face of so many castor, how are we to choose appropriate own castor? In the face of numerous castor, we want to see the caster wheel size. General caster wheel diameter, the greater the push, the more energy saving the obstacle ability the better, because castor first at the end of the 19th century western industrialization, so castor generally in inches, such as China's most supermarket trolley with 5 inch, 4 inch caster wheel. The current market popular castor size from 1 to 10 inches, the size of the commonly used 2 inch, 2. 5 inch and 3 inch, 3. 5 inch and 4 inch, 5 inch, 6 ', 8 ', 10 ', etc. , often need to promote commonly, such as supermarket shopping cart, logistics trolley, factory using 4 ~ 6 inch caster is preferred. But too much caster wheel diameter can make equipment center of gravity rises, the cost increase, so must carry on the comprehensive consideration. If the device does not need to often push, such as furniture, refrigerator, etc. , only need to move during cleaning, choose 3 inches below the casters. Castor again, need is the need to bearing, with the same diameter of casters, general manufacturers can produce several series for different bearing, such as light, medium, medium etc. , the method is to make the wheels and stents have different thickness or material. Calculate the load of a single caster to offer certain insurance coefficient, relatively flat on the ground, a single caster wheel load = ( Equipment had been present on the caster and quantity) ×1. 2 ( Insurance coefficient) ; If the ground not level off, the algorithm for the total weight of a single caster wheel load = equipment present 3, because no matter what kind of uneven ground, always at least three wheels support equipment at the same time, the algorithm is equal to increase the coefficient of insurance, more reliable, to prevent the bearing is not enough, lead to greatly reduce or castor life lead to accidents. In foreign company, bearing generally expressed in pounds, and most domestic use kg and their conversion relations are: 2. 2 pounds = 1 kg. Additional, still need to be aware of is the castor material, this is very important, we should choose to suit oneself according to the actual situation of our casters. The function of the brake and so on but also need to see the specific equipment.
