What It Does:

Serves as the heavy-duty 5-piece steel wheel rim assembly bolted to the front, center, and rear drive axle hubs on Caterpillar 740 and D series 35-40 ton articulated dump trucks to mount 29.5R25 (29.5-25) earthmover (OTR) tires. Composed of a rim base, two side rings, a bead seat band, and a lock ring, this 5-piece configuration securely anchors and locks the tubeless tire beads under high pneumatic pressure, maintaining airtight containment and transferring massive 6x6 drivetrain tractive and retarding torque directly to muddy, uneven, and rocky haul routes.

Importance:

A vital structural and safety load-bearing wheel assembly designed to carry massive payloads and withstand severe operating stresses across challenging terrain in quarrying, mining, and heavy civil earthmoving. Precision-engineered from a 350 kg high-tensile structural alloy steel construction with precision-machined gutter sections and reinforced bead seating areas, it effectively absorbs heavy cyclic side-thrust loads, harsh ground impacts, and torsional articulation stresses, preventing rim fatigue failure, gutter cracking, and air loss under demanding continuous site duty.
