Why do supermarkets use PU wheels as the wheels for manual hydraulic transport vehicles
When shopping in the supermarket, we occasionally see the staff pulling manual hydraulic trucks to transport heavy materials such as flour, rice, and cooking oil. The vehicles do not make any abnormal sounds while carrying heavy loads, as if a calm and quiet person is performing their skilled work without anyone else.
If we observe carefully, we can find that the wheels of the manual hydraulic transport vehicle are made of PU wheel material, strictly speaking, a type of plastic, with more additives than ordinary materials. Therefore, it has the following advantages:
1. It has excellent walking performance, good grip, smooth and lightweight, wear-resistant, and will not cause pressure marks when walking on the ground;
2. And its color is red, which is bright and easy to be noticed during driving. More importantly, the dark colored wheels are more resistant to dirt, even if they are contaminated with oil, mud, and other dirt, they are easier to clean;
3. More importantly, it has good elasticity and is suitable for performing various skillful movements such as rotation, acceleration, retrograde, jumping, and so on.
In addition to PU material wheels, there are also two types of wheels: polyurethane wheels and nylon wheels. However, in comparison, PU material manual hydraulic handling vehicle wheels are more suitable for supermarket use.
