Daily Walk-Around Tech Checks (Antenna, Cables, Sensors)

Introduction

Before starting work, it’s important to inspect the technology components that power the Intelligent Machine Control (iMC) system. These checks only take a few minutes and can prevent loss of accuracy or downtime during the shift.

⚠️ Safety Notes

  • 🔴 Always park safely: Lower the bucket to the ground, lock the control levers, and shut off the engine before doing checks.

  • ⚠️ Do not pull on cables: Always check connectors by hand, never yank wires.

  • ✅ Check daily: Make these inspections part of your regular walk-around.

Step-by-Step Instructions

  1. GNSS Antennas

    • Locate the GNSS antennas mounted on top of the cab.

    • Make sure they are:

      • Securely fastened to their brackets.

      • Clean, with no dirt, snow, or debris on the dome.

      • Free of cracks or damage.

    • Confirm both the main and auxiliary antenna are present (some jobs require dual-antenna setup).

  2. Antenna Cables

    • Follow the coaxial cables from the antennas into the cab.

    • Check that:

      • Connectors are tight (hand-snug).

      • Cable jackets are not cut, pinched, or worn.

      • Cables are routed away from sharp edges and moving parts.

  3. GNSS Radio or Modem (if equipped)

    • If using UHF radio corrections, check the radio device and antenna:

      • Confirm antenna is upright and firmly mounted.

      • Check that the coaxial connection is secure.

    • If using NTRIP/cellular corrections, confirm the modem box and SIM slot covers are closed and sealed.

  4. Sensors (IMU, bucket, and boom)

    • Inspect the visible sensor housings on the boom, arm, and bucket linkages.

    • Make sure:

      • Sensor brackets are firmly bolted on.

      • Wiring harnesses are not loose, pinched, or rubbing.

      • Protective covers are intact.

    • For tilt bucket or quick coupler sensors, confirm wiring connectors are fully clicked in.

  5. ICT Monitor in Cab

    • Check that the monitor is clean and free from cracks.

    • Confirm all connectors on the back of the unit are secure.

    • Ensure the mounting bracket is tightened so the monitor will not shift during operation.

Tips

  • If you find loose connectors, tighten them gently by hand.

  • If a cable or sensor looks damaged, do not operate until it is inspected by service personnel.

  • Keep a rag in the cab to wipe dust or rainwater from antenna domes.

  • If you regularly work in heavy brush or demolition, inspect more frequently.

Conclusion

Daily walk-around tech checks keep your iMC system accurate and reliable. By catching issues early, you avoid signal dropouts, incorrect bucket positions, or lost production time. A few minutes each morning can save hours of downtime later.
