Supermarket trolleys getting bigger? And how have its casters changed?

Let me start by telling you a cold fact you probably didn’t know. Supermarket carts are getting bigger.
Today’s supermarket trolleys are twice as big as those of 1975. Why is this? Citizen activist Ralph Nader argues that it’s a way for brazen capitalists to manipulate consumers: the trolleys are so big that you embarrass yourself if you buy just a little something.

You may not have noticed this change, because relatively, the cart under the universal wheel in recent years is also iterative update, you in the process of daily use, and did not give you to bring the implementation of resistance, so you are very noticeable.

A supermarket trolley why choose to use universal wheel?

The reason why supermarket trolleys use universal wheels is because they offer better maneuverability and flexibility to adapt to busy environments in supermarkets. Compared to regular wheels, universal wheels can swivel freely, making it easier for the vehicle to turn and move in tight spaces. In addition, the universal wheel can also reduce the friction between the trolley and the ground when turning, thus reducing the friction between the trolley and the ground and making the trolley easier to move. In supermarkets, shoppers usually choose the busier time to shop, when the aisles in the supermarket will be very busy. Supermarket trolleys with universal wheels are able to move more flexibly through the crowd, thus providing a better shopping experience for shoppers.

Second, where is the change in the supermarket trolley universal wheel?
First of all, the size, the size of the supermarket wheel has gradually evolved from the initial 2-3 inches to 4-5 inches, the size of the change to a certain extent to reduce the implementation of the resistance. In addition, with the iterative upgrading of technology, casters bracket, grease, bearings, wheel surface materials, etc. have undergone slight changes, these changes may seem insignificant, but the fundamental improvement of the supermarket cart propulsion is not enough to solve the problem.

Third, the future of the supermarket trolley

Supermarket trolleys with drive wheels as casters have now appeared on the market, and these trolleys make the shopping process easier in the visualized future. This kind of trolley will be popularized to a certain extent as the industry stabilizes and the price of driving wheels stabilizes. The combination of driving wheel + universal wheel will be another development direction of supermarket trolley.
