Dozers Include Intelligent Features

Technology continues to grow in the construction market and that includes equipping heavy machinery with tools designed to make the job easier.

For example, Komatsu America Corp. recently introduced the D155AXi-8 Radio Control dozer, the company’s first radio-controlled machine with intelligent machine-control technology.

The dozer is designed for applications where contractors may want to remove the operator from the machine but maintain high levels of efficiency and productivity.

For many operators, the ability to feel machine response to blade load is an important factor in effective dozing. This is naturally difficult for a radio-control application where the operator is separated from the machine.

The D155AXi-8 RC dozer is unique among radio-control dozers, as it has enhanced “intelligence” that automates operation from heavy dozing to fine grading to efficiently doze material.

The machine has the ability to sense and control blade load, optimize the start of the cut, and minimize track slip.

An automatic gearshift transmission and lock-up torque converter team up to select the optimal gear range, depending on jobsite conditions and load. They are designed to provide maximum operation efficiency.

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 up to 10 percent.

The SIGMADOZER blade, designed to dig and roll up more soil at the blade’s center, holds more material, reduces digging resistance, and dozes up to 15 percent more soil while using less power, compared to a typical semi-u blade.
