Caster is specially designed to reduce the physical burden of people when moving objects. It is not only suitable for professional large-scale use occasions, but also suitable for supermarkets. It will make our shopping environment more relaxed and pleasant to install casters on the trolleys of supermarkets. And in the supermarket cleaning is to promote all kinds of obstacles no longer need a lot of effort, so that there is no hiding place in the health dead corner. When the goods are placed, it is no longer necessary to worry about the difficulty of moving large and heavy goods. The goods can be easily moved to the desired position, and the casters can be slowly turned until they are satisfied.
General supermarket carts are installed with universal casters, which is mainly convenient for everyone in the shopping process to adjust the direction at any time. In the process of loading, the caster will bear the gravity of goods and the reverse force of the ground, and the impact force of obstacles when walking. Due to the eccentric distance of universal caster, the front and rear parts of the universal support rail will bear the force from opposite directions; and because the hardness of the bracket material is lower than that of the steel ball, when used under heavy load and high steering frequency, the rear edge of the upper rail and the front edge of the lower rail of the bracket are worn by the steel ball. In order to reduce wear and increase the service life of the bracket, it is necessary to add lubricating oil to the bracket frequently. In the case of small load, soft wheel can be selected to reduce vibration. For the case of large load, caster with plane bearing bracket can be selected.
The temperature of supermarket is relatively suitable, so when choosing caster, the requirement of temperature is relatively less. But in different places, we should also choose suitable castor materials with different temperatures, because the situation of cold and high temperature has a great impact on casters. The bigger the wheel of supermarket shopping cart, the more labor-saving. As a supermarket shopping cart caster, how to make customers more labor-saving is particularly important, because customers do not want to push a heavy car to buy goods. Therefore, supermarkets in the selection of shopping cart casters, must choose the wheel diameter of the caster.
