FJD Trion DC100L | 3D Dozer Guidance System

The DC100L puts the design in the cab of a dozer without taking the blade out of the operator's hands. It suits bulk earthworks, pads, dams, farm work and road formation where you want fewer pegs and less checking, and want to start with guidance before deciding on automatic control.

It runs on the same platform as FJD's DC100 automatic dozer control (sold as the H39 PRO until 2026), with the same tablet, software and workflow. The difference is that the DC100L shows the operator where the blade is and doesn't drive the hydraulics.

What Changes on the Job

• Fewer pegs and less checking. The design and the blade position are on the screen, so the operator can see what's left to cut or fill.
• Less material moved twice. Getting close to grade earlier means less trimming and less over-cut to fill back in.
• Works to a design, not one plane. Slopes, benches and complex surfaces come straight from the design file.

Mastless or Dual-Mast

In the mastless set-up, the two GNSS antennas go on the cab roof, with tilt sensors (IMUs) on the body and the blade. Nothing sits on the blade that can be knocked off, the operator's view stays clear and the install is simpler. The traditional dual-mast layout, with antennas on masts at the blade, is still available. FJD quotes about 15 minutes to calibrate dual-mast and 25 minutes mastless.

How It Works

The antennas give the dozer's position and heading, and the IMUs give the blade's attitude. The control box works out where the cutting edge is and the 10.1-inch tablet shows it against the design with cut/fill figures. The operator controls the blade. FJD's dozer software also includes elevation offset, blade-wear calibration and hold-slope tools. Ask us which apply in guidance mode.

Guidance Now, Automatic Control Later

FJD designed the DC100L to upgrade to DC100 automatic blade control by adding a control module, with valve, relay and CAN bus options for hydraulic and electro-hydraulic dozers. We're starting with guidance, so ask us if automatic control is on your radar.

Designs and Coordinate Systems

Import DWG, DXF or XML designs, or build slopes, depths and elevations on the tablet. You can load several designs into one job and switch between them. More than 6,000 coordinate systems are built in, and grid and geoid models download online. FJD's TerraMind cloud platform lets the office plan jobs, send designs and watch progress.

Corrections

The tablet has a 4G modem for network RTK corrections (subscription, or Geoscience Australia's free AUSCORS streams), and the system takes UHF corrections from your own base on 410–470 MHz or 902–928 MHz. The antennas need a clear view of the sky.

What We Need to Quote

Send us the dozer make, model and year, whether it's hydraulic or electro-hydraulic, whether you'd prefer mastless or dual-mast, and how you'll get corrections. We can arrange installation, calibration and operator training.
