Casters are used to reduce labor intensity and improve work efficiency. According to the application mode, conditions and requirements (convenient, labor-saving and durable), choose the casters suitable for your use correctly.
1. Size selection: Generally, the larger the diameter of casters, the more labor-saving it is, and the better the obstacle ability is. Because casters were first industrialized in the West at the end of the 19th century, casters are generally expressed in inches. For example, most supermarket trolleys in China use 5-inch and 4-inch casters. At present, the popular casters in the market range from 1 inch to 10 inches, and the commonly used casters are 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, etc. Generally, it is better to use 4 ~ 6 inches of casters for shopping carts, logistics trolleys and tool carts in supermarkets. However, too large a diameter of casters will increase the center of gravity of equipment and increase the cost, so comprehensive consideration should be given.
2. installation method: Generally, screw rods, plug rods, expansion rubber sleeves, etc. can be used for medium and light loads, while bottom plates can be used for heavy loads, or they can be directly welded to equipment. Generally, large companies have rich installation methods.
3. Brake: Functionally speaking, there are brake wheels, brake brackets universal, and the same brake is double brake, as well as tread brake, positive brake, side brake, etc. Contact caster factory specifically
4. Casters on the equipment layout: The layout is different, not only affect the cost, the feeling of driving is also greatly different!
5. Support selection: It is divided into directional and universal. Carbon steel is generally used as material, and various electroplating can be carried out, such as zinc plating, copper plating, nickel plating, chromium plating, spraying, etc., and stainless steel is also used.
6. Load-bearing: For casters of the same diameter, manufacturers generally produce several series for different load-bearing, such as light, medium and medium, etc. The method is to make the wheels and brackets have different thicknesses or materials. When calculating the load of a single caster, a certain safety factor should be given. When the ground is relatively flat, the load of a single caster = (total weight of equipment ÷ number of casters installed) × 1. 2 (safety factor); If the ground is uneven, the algorithm is as follows: the load of a single caster = the total weight of the equipment ÷ 3, because no matter what kind of uneven ground, there are always at least three wheels supporting the equipment at the same time. This algorithm is equal to increasing the safety factor, which is more reliable and prevents insufficient load-bearing, which leads to greatly reduced caster life or accidents.
7. Wheel material: This is very important, generally PU, TPR, PP, rubber, nylon, etc. As for the applicable temperature, surface hardness, ground environment, etc.
