Selection of wheel material. Generally speaking, the casters of supermarketShopping Trolley manufacturer cart should be selected according to the road conditions, wheel load and other conditions. Such as rubber wheel (PVC) can not resist acid, grease and other chemicals, while polyurethane and nylon are suitable for different environments;

2. Choice of soft and hard wheels: Super polyurethane wheels, nylon wheels and high-strength polyurethane wheels can be suitable for indoor and outdoor ground driving; high-strength artificial casters are suitable for hotels, hospitals and other quiet ground driving; 

3. The larger the wheels of supermarket Shopping Trolley manufacturer cart, the less effort For supermarket shopping cart casters, how to make customers more labor-saving is particularly important, because customers don't want to push a heavy car to buy goods. Therefore, when choosing shopping cart casters, supermarkets must choose casters with large wheel diameter. 

4. The temperature of the supermarket is relatively appropriate, so when choosing casters, there are relatively few requirements for temperature. Shopping Trolley manufacturerowever, caster materials suitable for different temperatures should also be selected in different places, because Yan Qian and high temperature have a great impact on casters. If you are in the north, you should choose polyurethane castors. Experiments show that polyurethane can rotate flexibly even at a low temperature of minus 45 degrees; 

5. As a caster of supermarket Shopping Trolley manufacturer cart, its bearing weight must also be calculated well. If customers buy relatively heavy goods, such as rice and casters, it will affect customers' shopping desire. To calculate the bearing weight, we must know the dead weight, Zui heavy load, single wheel and quantity of the transport trolley. This formula can be applied: T = e + Z / m * n; T = single wheel or required bearing weight; E = self weight of transport trolley; Z = Zui heavy load; M = number of all single wheels and casters; N = safety factor
