Komatsu HM300-2 is a rigid-frame articulated dump truck used in earthmoving, quarry, and construction applications. It is powered by a Komatsu diesel engine and designed for hauling material over rough terrain with high stability and traction. The HM300-2 features a front-mounted cab, articulated steering, and a rear dump body for efficient loading and unloading. Common specifications include all-wheel drive, hydraulic retarder, and operator-focused controls. Although sometimes grouped with wheel loaders in broad equipment listings, the HM300-2 is specifically a haul truck, not a wheel loader. It is used in material transport, site development, and mining support operations.
