Description
OEM-Quality Komatsu HD785-7 Front Corner Assembly
Maximize haul road tire life, directional stability, and front braking performance with a heavy-duty Komatsu HD785-7 Front Corner Assembly. Precision-engineered for Komatsu HD785-7 (91.7-tonne payload class) mechanical drive haul trucks, this drop-in modular front station unites steering geometry, oleo-pneumatic shock absorption, wheel hub rotation, and continuous force-cooled braking into a single heavy corner group.
Designed to handle severe impacts from mine loader drops and high-speed cornering on steep pit ramps, the HD785-7 front corner utilizes Komatsu’s independent MacPherson strut suspension design, allowing the front wheels to track ground contours smoothly without altering kingpin inclination angles.
Key Features & Benefits
Modular “Drop-In” Front Station Design: Pre-assembled corner group simplifies overhaul procedures by combining the suspension strut, steering knuckle, spindle, hub, and wet brake pack into one installable unit.
Independent MacPherson Strut Damping: Nitrogen-over-oil oleo-pneumatic strut absorbs severe haul road washboards, extending chassis frame fatigue life.
AP-FOUR Wet Multi-Disc Front Braking Integration: Integrates Komatsu’s sealed, force-cooled wet multi-disc brake pack for fade-free retarding down steep mine declines.
Forged High-Tensile Steel Kingpin Knuckle: Precision-machined steering knuckle and spindle geometry eliminate alignment deflection under heavy front axle loading.
Duo-Cone Sealed Wheel Hub Bearings: Heavy-duty tapered roller bearings with lifetime metallic face seals keep wheel bearing oil isolated from abrasive quarry slurry and dust.
