NewRoadProducts KOMATSU AMERICA Artic offers more than an engine update It's one thing to fulfill a mandate to meet emissions requirements. o True to form, however, Komatsu has used the opportunity to enhance the performance and productivity of its HM400-3 articulated dump truck. Powered by a Tier 4 Interim-certified SAA6D140E-6 engine generating 469 horsepower, the new 40-metric-ton-capacity artic has an updated body design that increases payload. In load-and- haul applications, the truck's low loading height of 10 feet 5 inches matches easily with 40- to 60-metric-ton hydraulic excavators or 5.5- to 6.5-cubic-yard wheel loaders. Two single-staged body lift cylinders provide the truck with a 70-degree dump angle. The new Komatsu Traction Control System (K-TCS) automatically provides optimum traction when operating in soft ground conditions. As ground conditions worsen, speed sensors located on four wheels detect tire slip- page, and automatic application of the inter-axle differential lock occurs. If tire slippage continues to be detected, four independent brakes can be applied to slipping wheels to regain traction. The HM400-3's six-speed, fully-automatic transmission uses an advanced electronic system to elimi- nate shift shock and torque cutoff.

Keeping good tires under big iron is essential to quar- ries operating at optimum 24/7 productivity. To that end, the Michelin X-QUARRY S tire features a square, reinforced shoul- der providing a large contact area, resulting in even tire wear. A thick sidewall band protects the rigid-dump-truck tire from abrasions and damage caused by rocks or other site debris. The tire's non-directional tread is unbroken in the center – with deep, angled grooves – to reduce vibration and enhance the ride comfort for the operator. Easy to repair, the X Quarry S tire has low rolling resistance, increasing the fuel efficiency of the truck, says Michelin.
