What It Does:

Serves as the heavy-duty 3-piece rim base mounted onto the wheel hubs of Caterpillar 725, 725C, 730, and 730C series articulated dump trucks via a 20-bolt hub pattern. Operating in conjunction with side rings and lock rings, it securely seats 19.5x25 / 23.5x25 earthmover (OTR) tires, maintains air sealing, and transfers high driving and braking torque from the axle to the ground.

Importance:

A critical structural load-bearing wheel component essential for payload distribution, machine stability, and safe hauling over severe off-road terrain, mud, and quarry surfaces. Engineered from a 150 kg high-tensile structural steel construction with precision-machined lock grooves and a reinforced 20-hole bolt circle, it effectively withstands immense vertical payload forces, cyclic torsional stresses, and heavy dynamic side-thrust impacts, preventing rim cracking, air loss, and tire bead slippage under demanding continuous duty.
