There are many different specifications and sizes for the wheels of a flatbed handcart, and there is no fixed and unified standard for selection. It mainly depends on the purpose and the required load capacity:
1. If it is mainly used to push heavy goods, a wheel diameter of around 200mm is more suitable. The wheel material should be rubber or PU, and it is recommended to choose a shaft with bearings for easier lifting.
2. If the goods cannot be pushed too heavy, a wheel diameter of about 120mm is sufficient. The tires can be made of foam material, which is relatively cheap. Of course, rubber or PU materials can also be used. The shaft axis does not need to be equipped with bearings, but lubricating oil should be regularly added to the shaft axis to make pushing easier.
