Remote Control Dozer

Remote Control Dozer

The D155AXi-8 RC crawler dozer is a radio-controlled machine with Intelligent Machine Control (IMC) technology.

It is designed for applications in which the operator should be removed from the cab in the interest of safety , but the need for high levels of efficiency and productivity remain , the company says. The line-of-sight remote-control allows operation up to 100 meters distant.
The D155AXi-8 RC uses a 15.24-liter , 354-horsepower Komatsu SAA6D140E-7 Tier 4-Final engine that features variable-geometry turbocharging , Komatsu diesel particulate filter , and a selective catalytic reduction system. An automatic gearshift transmission and lock-up torque converter provide the optimal gear range , based on job-site conditions and load , says Komatsu. The electronically controlled transmission locks up the torque converter to transfer engine power directly to the transmission , eliminating horsepower loss and cutting fuel consumption by as much as 10 percent , says the company.

The D155AXi-8 RC’s SIGMADOZER blade , patented by Komatsu and designed to hold more by digging and rolling material to the blade’s center , reduces digging resistance and moves up to 15 percent more soil , while using less power , says Komatsu , compared with using a typical semi-U blade.
