What is FJDynamics GPS Installation for Excavators?
A FJDynamics GPS installation equips your excavator with a sophisticated retrofit 3D machine control system. This technology moves beyond traditional 2D laser levels by using advanced GNSS (Global Navigation Satellite System) and RTK (Real-Time Kinematic) technology to achieve centimetre-level digging accuracy. By referencing satellite constellations, including the well-known Global Positioning System (GPS), the system provides the operator with a real-time, 3D view of the bucket’s position relative to the site design.
For UK contractors, this shift from traditional methods to 3D machine control is a game-changer. It directly addresses key operational challenges by delivering significant, measurable improvements in efficiency and safety. The core benefits include:
-
Reduced Over-digging: Work precisely to the design grade, eliminating costly rework and saving on expensive backfill materials.
-
Lower Fuel Costs: Achieve the target depth and slope in fewer passes, which cuts down on machine hours, fuel consumption, and overall wear and tear.
-
Improved Site Safety: Minimises the need for a grade checker to work in close proximity to the excavator, reducing the risk of accidents on site.
One of the most compelling advantages of the FJDynamics gps installation is its broad compatibility. The system is designed to be retrofitted onto almost any machine, breathing new life and precision into older 360 excavators and integrating seamlessly with modern fleets.
The Components of the FJDynamics 3D System
The system’s precision comes from a combination of high-quality, rugged components working in unison. The main hardware includes:
-
Dual GNSS Antennas: Mounted on the excavator, these establish the machine’s exact position and heading on the site.
-
High-Precision IMU Sensors: These track the real-time angle and movement of the boom, arm, and bucket.
-
The 10.1-inch Control Terminal: Installed inside the cab, this rugged touchscreen tablet acts as the operator’s interface, displaying the design plans and bucket position.
Why Retrofitting Beats Buying New Integrated Machines
While factory-fitted GPS systems are available on new machines, retrofitting your existing fleet offers distinct advantages. This approach is highly cost-effective, allowing you to upgrade your current 360 excavators for a fraction of the cost of a new machine. The system is also portable and can be transferred between compatible machines, offering excellent flexibility. Finally, it allows operators to continue using the cabs they know and trust, reducing the learning curve and maintaining productivity.
Pre-Installation Checklist: Tools and Environment
A successful FJDynamics GPS installation depends entirely on diligent preparation. Before a single tool is picked up, taking the time to prepare your machine, workspace, and equipment ensures accuracy, safety, and operational efficiency. A precise setup is the foundation for effective construction machine control guidance , preventing costly rework and maximising your investment from day one. Always prioritise safety; this process involves working with heavy machinery and sensitive electronics.
Your pre-start check should cover three key areas: safety protocols, essential tools, and software readiness. Following these steps methodically will make the physical installation process significantly smoother.
- **Safety First:** Before starting, ensure the machine is parked on level ground, the parking brake is engaged, and the ignition is off with the keys removed. Isolate the machine using your company's lock-out/tag-out procedure. Safely ground all hydraulic attachments, like the bucket, to release any residual pressure.
- **Tool Requirements:** Gather all necessary tools. You will need a comprehensive metric socket and spanner set, a high-quality magnetic digital level for sensor alignment, a torque wrench for securing mounts to factory specifications, and consumables like cable ties and protective wiring loom.
- **Software Preparation:** Check the official FJDynamics support website for the latest firmware for your control box and GNSS receivers. Download this to a USB drive beforehand to avoid delays caused by poor internet connectivity on-site.
Site Conditions for Calibration
The environment where you perform the initial setup is critical for system accuracy. The ground must be completely flat and level, as this is the baseline for all sensor calibrations. Your chosen location must also have a clear, unobstructed view of the sky to acquire a strong GNSS satellite lock. Avoid working near high-voltage power lines, radio towers, or large metal buildings, which can cause signal interference and corrupt your calibration data.
Hardware Inspection
A thorough hardware check is a vital step in any professional FJDynamics gps installation. Unpack all components and verify them against the shipping manifest. Critically, confirm that the sensor mounting brackets are compatible with your specific machine model, as a bracket for a 20-tonne excavator will differ from one for a smaller unit. Lay out the wiring loom and check that the cable lengths are sufficient for the full articulation of the boom, stick, and bucket, preventing snags or damage during operation.
Step-by-Step FJDynamics Hardware Mounting
Correct hardware placement is the foundation of an accurate and reliable machine control system. This section provides a clear, step-by-step guide to mounting the components, ensuring your FJDynamics gps installation is both dependable and durable from day one. Follow these professional-standard procedures to guarantee optimal performance and safety.
The core installation process involves five key stages:
- **Step 1: Mount the GNSS Antennas.** Secure the dual GNSS antennas onto a stable, vibration-free surface with a clear view of the sky. The machine's counterweight or cab roof are ideal locations. Ensure they are positioned symmetrically for the most accurate heading information.
- **Step 2: Attach the IMU Sensors.** Fit the three high-precision IMU (Inertial Measurement Unit) sensors to the main moving parts: one on the boom, one on the arm (dipper), and one on the dog-bone or bucket linkage.
- **Step 3: Install the Terminal Display.** Inside the cab, install the control terminal using the supplied heavy-duty RAM mount. Position it for easy operator access and clear visibility without obstructing the view of the work area.
- **Step 4: Route the Wiring Harness.** Carefully route the main wiring harness from the antennas and sensors back to the terminal. Secure it along existing hydraulic lines using high-quality zip ties, leaving enough slack for full machine movement.
- **Step 5: Connect to Power.** Finally, connect the system to the machine’s power supply. The FJDynamics system is compatible with both 12V and 24V systems, making it suitable for almost any piece of plant machinery.
Sensor Placement Precision
Achieving sub-centimetre accuracy hinges on correct sensor placement. The sensor on the bucket linkage (dog-bone) is the most critical, as it directly measures the bucket’s angle and provides the final data for vertical accuracy. For permanent installations on rough terrain, welding the mounting plates is the most robust solution. Heavy-duty magnets offer flexibility but must be checked regularly. Always ensure each sensor is perfectly aligned with the centre-line of the component it is mounted on.
Cable Management for Heavy Plant
Protecting your wiring is paramount for system longevity. During your FJDynamics gps installation, identify and avoid all “pinch points” where cables could be crushed or sheared during boom and arm articulation. We strongly recommend using protective conduit for wiring in high-wear areas, especially near the bucket. To withstand the UK’s unpredictable climate, ensure all connections are tight and use the supplied weatherproof plugs to prevent water and dust ingress, which can lead to system failure.
Configuring Signals and Centimetre Calibration
Once the physical hardware is mounted, the next phase of your FJDynamics gps installation is to configure the software and calibrate the system to your specific machine. This is a critical stage where precision is established, ensuring every movement of the bucket is accurately tracked. Proper calibration is not just about performance; it’s a cornerstone of site safety and project compliance.
Setting Up RTK for UK Sites
To achieve centimetre-level accuracy, the system requires Real-Time Kinematic (RTK) corrections. In the UK, you have two primary options: using a dedicated FJDynamics base station on-site or connecting to an Ntrip network via a SIM card. A base station is ideal for large, long-term projects, while an Ntrip subscription offers flexibility for operators moving between sites. In remote areas like rural Gloucestershire or the Highlands, signal drop-outs can occur. Always ensure you have a reliable data provider to maintain the sub-3cm accuracy threshold essential for modern civil engineering projects.
The Excavator Dimension Input
The system’s accuracy depends on precise measurements of your excavator. Using a tape measure, you must input the exact dimensions into the control terminal with millimetre precision. Key measurements include:
-
Distance from the machine’s centre of rotation to the main boom pin.
-
Length of the boom and the stick (dipper arm).
-
Dimensions of the bucket, including tip-to-pin distance.
-
Offsets for any quick-hitch attachments.
It is vital to account for different buckets and hitches, as each will alter the final position of the cutting edge. Offset calibration is the process of aligning the digital bucket tip with the physical ground.
With the dimensions entered, the system requires both static and dynamic calibration. Static calibration verifies the angle sensors while the machine is stationary. Dynamic calibration is a crucial part of the FJDynamics gps installation, involving moving the boom, stick, and bucket through their full range of motion to teach the system precisely how all the components move together. This ensures the digital model perfectly mirrors the machine’s real-world articulation.
Finally, perform a “benchmark” test. Place the bucket tip on a known survey point and verify that the coordinates on your terminal match the benchmark’s coordinates within your project’s tolerance. This final check confirms your professional setup is complete and ready for safe, accurate work. For expert, hands-on training with machine control systems, visit us at vallyplanttraining.co.uk .
