For cars, tires are consumables that gradually age with the increase of driving frequency and time, until they face disposal. Generally speaking, it takes about 5 years or 60000 kilometers from the beginning of use to disposal. For manual handling vehicles, their wheels are the top consumables among all components.
Wheels are extremely important for manual handling vehicles. They are the feet of the handling vehicle, an essential tool for walking on the ground, a carrier for carrying the hydraulic oil pump and heavy objects of the handling vehicle, and a key factor in improving the work efficiency of the handling personnel. However, as the running time of the wheels of the transport vehicle prolongs, their material gradually ages, greatly reducing the speed and performance of the transport vehicle. In order to prepare for replacing the wheels in advance, we need to know how many years PU wheels can be used after being installed on the transport vehicle.
There is actually no clear deadline for the service life of PU material wheels for manual handling vehicles, and no relevant unit tests the service life of PU wheels like testing car tires. But we can determine whether replacement is needed based on the damage and operation of the wheels.
