Komatsu HM300-5 Dump Truck

When the ground is soft and slippery, and loads of earth need to be moved, there is one dump truck that will cut across the job site and get the job done – the Komatsu HM300-5.

Gripping the ground with a state-of-the-art traction control system that is used in dozers and rigid dump trucks, the Komatsu HM300-5 articulating dump truck detects wheel slips and automatically engages the inter axle lock to improve machine performance.

Powered by an 11.2 liter 332 HP Tier 4 Final diesel engine and capable of carrying 30.9 tons of earth and rocks, the Komatsu HM300-5 is a powerful and capable dump truck for construction jobs sites, golf course developments, mining and quarrying, and beach sand replenishment.

The Komatsu HM300-5 is designed for operator control. The center-located operator seat, short-nose design, convex side mirrors and color rearview monitor provides the operator with a clear view of the surrounding area. The ergonomically designed curved dashboard enables quick-glance system checks and position switches within easy reach of the operator.  An electronic hoist control lever is within easy reach, and a body seating shock sensor detects the body and reduces the lowering speed just before seating on the frame.

The cab is mounted with ROPS/FOPS viscous mounts to dampen vibrations. The low-noise engine, hydraulically driven fan and hydraulic pumps are mounted with rubber cushions to further dampen noise pollution and create a quiet, low-vibration, dustproof cab.

The air suspension seat is adjustable to the operator’s weight, dampens vibrations from the machine and reduces operator fatigue. The tilt-away steering column and telescopic steering wheel are adjustable to the desired operator position. Two 12-volt outlets provide the operator with the power to keep phones and music players charged.

Measuring 33 feet, 8 inches long and 9 feet 6 inches wide, the robust Komatsu HM330-5 has a 45-degree articulation.  The 17 foot, 3-inch dump swings up to a 70-degree angle, ensuring that all of the material slides out of the bed.
