Komatsu HM300-2 is a rigid-frame articulated dump truck used in heavy construction, quarrying, and earthmoving applications. It is designed for hauling large volumes of material over rough terrain and short to medium distances. The HM300-2 typically features a diesel engine, all-wheel drive, and a high-capacity dump body for efficient material transport. Its articulated steering improves maneuverability in confined job sites, while the suspension system supports stability and operator comfort. Common uses include site development, road building, mining support, and bulk material handling. The model is part of Komatsu's HM series of off-highway haul trucks.
