ISUZU CYZ 20 YARD DUMP TRUCK
20 YARD DUMP TRUCK
The Isuzu CYZ (part of Isuzu’s legendary Giga C-Series lineup) is an ultra-rugged, 6×4 heavy-duty commercial dump truck engineered specifically to move high-volume bulk aggregates under punishing off-road conditions. Outfitted with a premium, reinforced 20-cubic-yard high-tensile steel dump body, this truck is highly favored for rental applications in mining operations, mass site excavations, civil infrastructure projects, and heavy quarry hauling.
Driven by Isuzu's massive, high-displacement 6-cylinder common-rail turbocharged diesel engine (such as the 6WF1 or 6WG1 series depending on regional configuration), it generates incredible low-end torque to pull maximum legal payloads smoothly up steep quarry ramps. For reliability in the field, it features a heavy-duty double-channel chassis frame that actively resists torsional bending, paired with an extra-strength leaf spring suspension system built to handle punishing impact drops from large excavators.
The driver's cabin boasts an ergonomic curved dashboard layout, a full air-suspension seat to minimize fatigue on rough haul roads, and a comprehensive, wide-angle mirror system that reduces blind spots on active, high-traffic worksites.
