Komatsu K980 Off-highway trucks tech specs

Overview

The Komatsu K980 (2016–2024) is an ultra-class off-highway dump truck aimed at mining operations where production depends on moving hundreds of tonnes in every haul cycle. Its 627.999-ton operating weight and 362.874-ton payload put it firmly in the same working class as the Cat 797 and Cat 798. The Komatsu SSDA18V170 engine produces 2,495 kilowatts and 13,771 Nm of torque, with an AC electric drive system handling power delivery under sustained heavy loads.

Expert rating: 4 stars

Performance & Efficiency

The Komatsu SSDA18V170 engine delivers 2,495 kilowatts and 13,771 Nm of maximum torque, providing the power needed to move a 362.874-ton payload through demanding haul cycles. The AC electric drive system is suited to repeated heavy-load operation, while the 64 km/h maximum forward speed supports productive travel across longer mine roads. The dump body raises in 21 seconds and lowers in 16 seconds, helping reduce stationary time during unloading, while hydraulic relief pressure is rated at 172.4 bar.

In Comparison

Cat 797: Carries a nearly identical 363-ton payload and offers higher stated engine power and maximum travel speed, while using a 7-speed mechanical powershift transmission instead of AC electric drive.
Cat 798: Offers a higher 372-ton payload with the same 64 km/h maximum speed and also uses an AC drive system.
Komatsu K980: Combines a 362.874-ton payload, 2,495-kilowatt engine, and AC electric drive, placing it between the two Cat models as a high-capacity electric-drive option for large mining fleets.

Final Verdict

Rated 4 stars, the Komatsu K980 is a serious ultra-class mining truck within the AED 14,700,000–29,000,000 range. Its 362.874-ton payload, 2,495-kilowatt engine, AC electric drive, and quick 16-second body lowering time make it well suited to high-production mines, although its 627.999-ton operating weight brings the infrastructure and maintenance demands expected from equipment of this scale.
