Freezer casters are an important accessory for moving the freezer. The quality of the freezer casters directly affects the moving effect of the freezer in real life. So when choosing the freezer casters, what aspects can you consider?
1. Wheel material: This is very important. Generally, there are PU, TPR, PP, rubber, nylon, etc. As for the applicable temperature, surface hardness, and ground environment, etc.
2. Selection of size: The larger the diameter of ordinary refrigerator casters, the less effort it takes to propel, and the better the ability to overcome obstacles. Since refrigerator casters first formed industrialization in the West at the end of the 19th century, the size of refrigerator casters is generally expressed in inches, such as China Most supermarket trolleys use 5-inch and 4-inch freezer casters. At present, the sizes of casters for refrigerators popular in the market range from 1 inch to 10 inches, and the commonly used sizes are 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, etc. For those that often need to be pushed, such as supermarket shopping carts, logistics trolleys, tool carts, etc., it is better to use 4-6 inch freezer casters. However, if the diameter of the caster wheel of the refrigerator is too large, the center of gravity of the equipment will rise and the cost will increase, so comprehensive consideration should be carried out. If the equipment does not need to be pushed frequently, such as furniture, refrigerators, etc., it only needs to be moved when doing hygiene, and the casters of the refrigerator below 3 inches can be used.
3. Look at the load-bearing: For refrigerator casters of the same diameter, ordinary manufacturers will produce several series for different load-bearing, such as light, medium, medium, etc. The method is to make the wheels and brackets have different thicknesses or materials. When calculating the load of a single Wanda refrigerator caster, a certain insurance factor should be given. When the ground is relatively flat, the load of a single refrigerator caster = (total weight of the equipment ÷ the number of installed refrigerator casters) × 1.2 (insurance factor); if the ground is uneven, then The algorithm is, the load of a single caster wheel of the refrigerator = 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. The life of casters is greatly reduced or accidents are caused. In foreign-funded companies, the load-bearing is usually expressed in pounds, while in China most of them are expressed in kilograms. Their conversion relationship is: 2.2 pounds = 1 kilogram.
4. Bracket selection: It is divided into directional and universal. The material is generally carbon steel, which can be subjected to various electroplating, such as galvanizing, copper plating, nickel plating, chrome plating, spraying, etc., and stainless steel is also available.
5. Brakes: In terms of function, there are wheels with brakes, and universal brakes with brake brackets. The two brakes are double brakes. There are also tread brakes, positive brakes, side brakes, etc. Please contact the refrigerator caster factory for details.
6. Installation method: ordinary medium and light loads can use screw rods, insert rods, shrink rubber sleeves, etc., and heavy loads can use bottom plates or be directly welded to the equipment. The installation methods of ordinary large companies are very generous.
7. The arrangement of the casters of the refrigerator on the equipment: the arrangement is different, which not only affects the cost, but also greatly affects the feeling of propulsion.
Casters are now more and more widely used in vegetable cabinets, refrigerators, freezers and other freezer equipment, and their functions are becoming more and more obvious. Therefore, when configuring freezer casters, you must choose from multiple aspects to ensure service life and application performance. , in order to give full play to the maximum effect of the casters on the freezer.
