Doosan Infracore
Doosan Infracore North America, LLC, expanded its wheel loader lineup with the new DL580-5. Capable of heavy-duty construction tasks, it combines extra-large capacity with efficiency and productivity.
Its key feature is the ability to fill a 24-ton, over-the-road truck in just two passes. This comes from an enhanced front workgroup, featuring a reinforced Z-bar, larger-profile arm, and lift-cylinder geometry, that improves lifting capacity and performance.
DL580-5 is also equipped with higher-volume steering pump and cylinders to help maintain steering efficiency with larger loaded weights, and a heavier counterweight that offsets the larger load capacity. Heavier front and rear axles, with six-disc outboard brakes on each hub, produce more efficient breaking with loaded weights.
Double circuit axle coolers, which come standard, improve durability and braking performance. The design also protects against overheating of the axle assemblies, via active cooling and dual radiators with sensor-based automatic temperature regulations.
Other standard features include electric steering, which can be adjusted with a left-hand control. Lower-profile tires, on a larger-diameter and wider rim, enhance traction. Like all Doosan wheel loaders, a rearview camera provides exceptional visibility.
Also increasing efficiency and productivity are three new aggregate buckets. Constructed of high-strength alloy steel with capacities of 8, 9 and 10 cubic yards, the buckets allow for SAE 110-percent overfill – to account for moisture density of aggregate for wetter substrate. Not only designed for oversized capacity, the buckets are durable, built to withstand the abrasive nature of the material.
