Komatsu has officially approved the K-Tec 1237 ADT scraper for use with its HM460-6 articulated dump truck. This pairing allows a single operator to manage mass earthmoving operations by utilizing the truck as a towing vehicle for the high-capacity scraper.
Why it matters
This approval creates a dual-capability asset for construction projects, enabling operators to streamline earthmoving tasks with a single power unit. Komatsu maintains a one-year unlimited warranty for the truck when paired with the scraper to support this operational shift.
The HM460-6 features a 518-horsepower engine and a nine-speed transmission with intelligent gear control, while the K-Tec 1237 ADT offers a 37-cubic-yard capacity. The truck delivers a 23% torque increase over the previous HM400-5 model.
The players
Komatsu
This multinational corporation is a leading manufacturer of construction, mining, and military equipment.
K-Tec
This company specializes in the design and manufacturing of pull-pan earthmoving scrapers for heavy construction.
The details
The scraper attaches directly to the articulated truck chassis, while the HM460-6 utilizes a traction control system paired with cross-axle differential locks to manage heavy loads. The vehicle is powered by an all-new DBA127 diesel engine designed without exhaust gas recirculation technology.
Timeline
The HM460-6 was introduced in 2026 at CONEXPO-CON/AGG.
Compatibility approval for the scraper was confirmed on October 22, 2026.
Roadmap
This integration marks a broader industry trend toward maximizing the versatility of heavy machinery through modular attachments. By certifying third-party tools for its latest dump trucks, Komatsu is evolving its equipment strategy to compete with multipurpose earthmoving solutions.
Owners can secure extended warranty coverage for the HM460-6 for up to 60 months or 10,000 hours of operation. This certification provides contractors in North America with verified operational guidelines for optimizing their existing fleet assets.
The takeaway
Operators should utilize the approved pairing to increase efficiency in mass earthmoving while ensuring warranty compliance. Leveraging modular attachments on high-torque platforms remains a primary strategy for reducing overhead costs in large-scale construction projects.
