Hitachi ZW220 is often used in construction sites, gravel yards, ports, mining and other complex terrains with sharp rocks and potholes . The rims used must take into account factors such as working strength, load capacity, stability and tire matching . We produce 19.50-25/2.5 rims to match it according to its performance.
The 19.50-25/2.5 rim is a rim specification widely used in medium-sized construction machinery, especially suitable for 19.5-25 or 20.5-25 construction tires. It perfectly matches the weight and tire specifications of the loader, while providing high load-bearing capacity, good impact resistance and easy-to-maintain structural advantages .
What are the advantages of using 19.50-25/2.5 rims on a Hitachi ZW220 wheel loader?
Hitachi ZW220 wheel loader is equipped with 19.50-25/2.5 specification rims, which has the following obvious advantages and is particularly suitable for heavy-load and high-intensity working environments such as quarries, mines, steel mills, etc.
The main advantages of matching with 19.50-25/2.5 rims:
1. Match larger tires to improve load-bearing capacity
It is usually equipped with 23.5R25 large-size tires to provide higher load-bearing capacity, making the ZW220 more stable and reliable when loading heavy objects (such as stones and slag).
2. Larger contact area and stronger traction
The matching tire has a wider tread, which increases the contact area with the ground; it enhances traction performance and effectively prevents slipping on soft and slippery surfaces.
3. Strong impact resistance, suitable for harsh working conditions
The 19.50-25/2.5 rim is usually a 5PC reinforced structure with stronger resistance to deformation and impact; it is more suitable for coping with the impact stress of uneven roads and frequent loading and unloading in mining areas.
4. Improve the stability of the whole machine
Larger rims with higher tire pressure make the center of gravity of the whole machine more stable; when loading high-density materials or the center of gravity is offset, the risk of overturning is lower.
5. Long service life and low maintenance cost
Thickened material + 5PC split structure design facilitates quick repair and replacement of parts; reduces downtime and maintenance costs of the whole machine caused by rim damage.
Hitachi ZW220 is equipped with 19.50-25/2.5 reinforced rims, which is an upgraded option designed for heavier, harsher and more efficient working environments. It not only improves the performance of the entire machine, but also enhances operational reliability.
