Industrial logistics trolleys should use casters of different materials for different purposes. Casters of different materials have different physical and chemical properties. The material of the casters is different, the use environment is different, and the service life of the casters is also different. When using casters, the caster purchaser should clarify the characteristics of the casters and use them properly to avoid unnecessary losses. Shangxin Industrial Casters introduces 4 methods of selecting logistics vehicle casters.
1. Size selection of logistics vehicle casters
Generally speaking, the larger the diameter of the caster wheel, the more labor-saving and the more obstacles the better, because the wheel was industrialized for the first time in the West in the late nineteenth century, so the caster wheel is generally expressed in inches. For example, Chinese supermarket carts mainly use 5, 4 inch casters. At present, the popular casters on the market are from 1 to 10 inches in size, such as Huiyi casters, usually 2 inches, 2.5 inches, 3 inches, 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, 12 inches, etc., usually It needs to be promoted, such as supermarket shopping carts, logistics giant wheels, etc. Tool carts are equipped with 4-6 inch casters. However, the diameter of the casters is too large to increase the center of gravity and increase the cost. If the equipment does not need to be promoted frequently, such as furniture, refrigerators, etc., it only needs to be moved when it is hygienic. Choose 3-inch casters.
2. The carrying capacity is not excessively wasted and not overloaded.
Choose the right industrial logistics vehicle casters, don't waste the load-carrying capacity of the casters, light casters can do the work, and heavy casters are obviously a great use. Do not exceed the bearing capacity of the casters, overloading will seriously affect the service life of the casters. For casters with the same diameter, the general manufacturer will produce multiple series for different load-bearing, such as Qingdao Dashi casters, light, medium and heavy. The way to do this is to make the wheels and brackets different thicknesses or materials. When calculating the single foot load, a certain insurance factor is given. When the ground is flat, single foot load = 1.2 (insurance factor); if the ground is not smooth, the algorithm is, single wheel load = 3 of the total weight of the equipment, at least on any uneven ground, at least always. The three wheels support the equipment at the same time, which is equal to the increase of the insurance factor, which is more reliable, and prevents insufficient load, which will greatly reduce the life of the casters or cause accidents. In foreign companies, weight bearing is usually expressed in pounds, while most domestic kilograms are converted to 2.2 pounds = 1 kilogram.
3. Performance of casters
Industrial casters of different materials have different use occasions, and the environment of the place of use should be fully considered when using them. Use different casters according to the environment. In the case of acids and alkalis, cast iron wheels are not suitable. If cast iron wheels are used, the caster will rust and corrode causing it to fail to spin properly. In textile mills and garment factories, where there are many steel wires or thread ends, it is appropriate to use casters with anti-tangle function to avoid winding the bearings or entering the steering rail track when the wheels are turning. In high-temperature occasions, casters made of high-temperature phenolic resin or cast iron wheels or high-temperature resistant nylon wheels should be used to avoid thermal deformation of the casters and prevent them from working properly. In cold regions, industrial casters with larger tolerances are suitable to avoid cold cracking due to cold shrinkage. Cast iron wheels should be used where there are more nails or glass. On uneven ground with uneven ground, casters with large wheel diameter and strong impact resistance should be used. If the wheel is too small and the impact ability is poor, the life of the caster will be greatly shortened.
4. The installation method matches
Choose according to the feasibility of the installation. Generally speaking, for light and medium loads, screw rods, plug rods, bottom plates, etc. can be used, or directly welded to the equipment. The installation methods of casters produced by Shangxin Casters are very rich, which can meet various needs.
5. Brake adaptation requirements
Choose according to braking requirements. From a functional point of view, there is a brake wheel, a brake bracket, and the two brakes are double brakes, including tread brakes, ordinary brakes, side brakes, etc. For details, contact Shangxin caster manufacturers.
