The HD465-10 and HD605-10 mechanical haul trucks represent an upgrade from the previous -8 models, according to Komatsu. The company says the haul trucks are designed to help increase productivity and improve fuel efficiency in mining and aggregate applications. The HD465-10 is a 60-ton rigid-frame machine with a high-payload capacity and efficient hauling capabilities. The HD605-10 mechanical haul truck, meanwhile, is a 70-ton rigid-frame model designed for reliability and durability. Both trucks offer a tight turning radius for easy navigation on narrow haul roads, as well as ergonomically designed cabin features for operator comfort during long shifts.
Rigid haulers deliver high productivity
Two new sizes joined Volvo Construction Equipment’s hauler lineup for quarrying and light mining. The R60 (55-ton) and R70 (65-ton) rigid haulers feature low centers of gravity, balanced weight and a tough-yet-flexible chassis. According to Volvo CE, the R60 has a body volume of 47 cu. yd. while the R70 offers 55.6 cu. yd. The trucks feature a V-shaped haul body for maximum load retention, the company says, and minimal carryback post-dumping. The dumping process itself is speedy thanks to a fast-tip system, Volvo CE says. Additionally, an optional onboard weighing system helps operators apply the 10/10/20 payload policy by which the machine can take 10 percent overload for 10 percent of the time but should not exceed 20 percent.
Lighter bodies producing higher payload capacity
Philippi-Hagenbuch developed a custom-engineered approach to manufacturing lightweight mining bodies, maximizing capacity and durability. Previously manufactured with Hardox 450 steel, Philippi-Hagenbuch now designs and engineers bodies with Hardox 500 Tuf steel. According to the company, this decreases weight while increasing abrasion resistance, leading to a 10 to 20 percent higher payload capacity and extended body life. Making the switch from 450 to 500 Brinell steel lightens up the mining body, Philippi-Hagenbuch adds, decreasing the body weight by up to 20 percent. This translates to added payload capacity. For a 100,000-pound mining body, the company says the new steel brings that number down to 75,000 to 80,000 pounds, saving about 20,000 to 25,000 pounds and boosting capacity by up to 12.5 tons.
