HD Hyundai Construction Equipment North America expanded its HX crawler excavator product line with two new large-frame mass excavators. According to Hyundai, the 82-ton HX800A L and the 100-ton HX1000A L are designed to meet the needs of high-volume earthmoving, mining and quarrying applications. The HX800A L has a 528-net-hp engine while the HX1000A L is equipped with a 620-net-hp engine. Each machine can be configured with various boom and arm configurations to match the material being excavated. The HX800A L supports buckets in the 4.5- to 7-cu.-yd. capacity range. The HX1000A L, meanwhile, supports buckets in the 7- to 8.9-cu.-yd. range. As Hyundai describes, both new excavator models offer selectable power modes and an electronic power-optimizing system for control over machine power and efficiency.
New North American excavators replace previous models
Volvo Construction Equipment launched two midsize crawler excavators in North America, expanding its newest generation of excavators. The EC260 replaces the EC250 in Volvo CE’s lineup while the EC300 is an update of a previous series model.

When the new excavator series was introduced, Volvo CE says it represented the most significant update to its excavator lineup in two decades.
Wheel loader comes with several automation features
Komatsu launched the WA700-8 wheel loader as an option for aggregate producers. The company says the WA700-8 offers substantial improvements in performance, efficiency and operator comfort compared to its predecessor: the WA700-3. Compared to the previous model, the WA700-8 delivers up to 8 percent more gross power and 15 percent more torque to handle demanding work environments, Komatsu says. Additionally, the loader provides a 6 percent increase in lifting force and rated load, allowing operators to handle larger volumes of material more easily. The WA700-8 also offers up to 8 percent more fuel efficiency, helping to reduce operating costs while maintaining high productivity, according to Komatsu. Automation features such as an automatic digging system, semi-automatic approach and semi-auto dump systems simplify repetitive tasks, helping operators to optimize load cycles.
