28.00-33/3.5 rim for Construction Equipmen Wheel loader CAT 988H
Description
For the CAT 988H wheel loader, which uses 28.00-33/3.5 rims, the selection and requirements of the rims are crucial, as they directly affect the machine's load-bearing capacity, stability, and operational safety.
The CAT 988H is a large wheel loader with a working weight of approximately 72–75 tons and a bucket capacity of 12–14 m³. The 28.00-33/3.5 rims must withstand the high impact forces when the machine is fully loaded and transporting ore and gravel. The rim material generally requires high-strength, high-quality steel to ensure it does not bend or crack under extreme working conditions.
A 28-inch width supports large, wide-body tires, ensuring sufficient contact area and improving traction. A 33-inch diameter ensures high ground clearance, adapting to uneven terrain such as mines and gravel plants. A 3.5-inch flange thickness provides sufficient bead strength to prevent tire slippage or deflation.
Wheel rims typically employ a 5PC (5-piece concrete) split design, enhancing strength while facilitating maintenance. The high-strength split structure can withstand heavy-load impacts from shoveling, vibrations from uneven road surfaces, and impacts from crushed stone in mines and ports.
The rim surface must be treated with an anti-corrosion coating or paint to resist mud, ore, rainwater, and chemical corrosion. This extends rim life and reduces maintenance costs.
CAT 988H requirements for 28.00-33/3.5 rims can be summarized as follows: 1. High load-bearing capacity, capable of withstanding full-load operation by large loaders; 2. Tire matching to ensure sufficient contact area and traction; 3. Strong structure, split design, impact resistance; 4. Sufficient flange thickness to prevent tire slippage; 5. Corrosion resistance and durability, suitable for harsh environments such as mines and ports; 6. Improved safety and operational efficiency.
