Komatsu America Corp. unveiled two excavators and two dozers during its Job Site of the Future event.

The company released the PC360LCi-11 and PC490LCi-11 hydraulic excavators, as well as the D155AXi-8 and D61EXi/PXi-24 crawler dozers. According to the company, all four of the new machines are a part of the expansion of Komatsu’s intelligent machine control family.

Both the PC360LCi-11 and PC490LCi-11 hydraulic excavators can operate on almost any jobsite. The PC360LCi-11 comes with a 257-hp Tier 4 Final engine, and the PC490LCi-11 comes with a 359-hp Tier 4 Final engine. The excavators use an auto grade assist feature that allows the boom to adjust the bucket height automatically, tracing the target surface. Komatsu adds that both models incorporate realistic 3-D displays on LCD screens so operators can view various work conditions around the machine.

The D155AXi-8 radio-control dozer, powered by a 354-hp Tier 4 Final engine, is Komatsu’s first radio-controlled machine. The company says the dozer can achieve high levels of efficiency and productivity even without an operator inside the machine. The D155AXi-8 dozer can sense and control blade loads, optimize the start of the cut and minimize track slip. An automatic gearshift transmission and lock-up torque converter also help to select the optimal gear range on the dozer to fit different jobsite conditions.

Komatsu’s D61EXi/PXi-24 dozer, which features a 168-hp Tier 4 Final engine, can sense blade load and minimize track slips. The machine eliminates the need to install or remove blade-mounted sensors each day, which Komatsu says saves on wear and downtime. The dozer also allows for automated operation from heavy dozing to fine grading.
