Articulated Truck FAQs


How does the Komatsu articulated rock truck compare to 40 ton rock truck models in payload and fuel efficiency?
The Komatsu HM400 5 stands out in the 40 ton rock truck class, offering a heaped capacity of approximately 24 m³ (31.4 yd³) and around 466 HP—providing more hauling power and productivity. In contrast, the HM300 5, though lighter, delivers excellent fuel efficiency and agility for tighter work sites. These features make each model an ideal choice depending on your site conditions and payload needs.

What rock truck specs matter most when comparing articulated dump trucks?
Key specs include payload capacity, heaped volume, horsepower, and transmission type. Komatsu’s HM-series delivers Tier 4 Final compliance, Komatsu Traction Control, and proven K‑ATOMiCS transmissions. Higher horsepower boosts performance on grades, while payload meters and smart features improve productivity and safety.

Is rock truck rental in Canada available for Komatsu articulated dump trucks?
While SMS Equipment primarily sells Komatsu HM300 5 and HM400 5 models, we also offer tailored rental options across Canada—combining flexibility with trusted rock truck reliability. Contact your nearest branch for availability and pricing.

What safety systems are in place that echo rock guarding a truck or rock guard for trucks functionality?
Both HM300 5 and HM400 5 include features like hydropneumatic suspension, durable body design, and standard rear view cameras, minimizing rock damage and maintaining stability during heavy haul cycles. These systems act like passive rock guarding to preserve equipment integrity and safety on rugged sites.

How do Komatsu wiggle wagons fare in terms of remote operation?
Komatsu HM-series trucks are renowned for durability and remote-service readiness. With KOMTRAX telematics and robust dealer support across Canada, operators benefit from proactive maintenance and minimal downtime—even in remote sites.
