For cars, tires are consumables. As driving frequency and usage time increase, tires will gradually age and eventually need to be scrapped. Normally, it takes about 5 years or 60000 kilometers from the beginning of use to disposal. For manual handling vehicles, the wheels are the top consumables among all components.

The wheels are crucial for manual handling vehicles. They are like the "feet" of the handling vehicle and are essential tools for the vehicle to walk on the ground. They not only carry hydraulic oil pumps and cargo, but also play a key role in improving the efficiency of the handling personnel. However, with the prolonged use of the wheels of the transport vehicle, their materials will gradually age, significantly reducing the speed and performance of the transport vehicle. In order to prepare for wheel replacement in advance, we need to know how many years PU material wheels can be used after being installed on the transport vehicle.
There is actually no clear age limit for the service life of PU material wheels for manual handling vehicles, and there is no relevant organization that conducts life tests on PU wheels like testing car tires. However, we can determine whether replacement is necessary based on the degree of damage to the wheels and their actual operating condition.
