• Haul Briefing – Coordinate with dozer, grader, and excavator operators on daily load volumes and routes.

Midday: Loading, Hauling, Dumping

Most of the shift is spent cycling between loading and dump zones:

• Hauling Loads – Maneuver massive vehicles through rough terrain while maintaining constant radio contact with site control.
• Dumping Material – Back into stockpiles or overburden areas safely, following site flagger or spotter instructions.
• Environmental Monitoring – Watch for changing weather or ground conditions, including mud, dust, or icy surfaces.
• Equipment Awareness – Stay alert for other machines, light vehicles, and overhead hazards.

Afternoon: Wrap-Up and Reporting

Toward the end of the day:

• Final Loads – Complete scheduled hauls before the end-of-shift cut-off.
• Post-Operation Check – Grease fittings, report wear or damage, and log mechanical issues.
• Daily Report – Submit haul counts and inspection logs via tablet or paperwork.

Challenges and Rewards

Challenges:

• Physical endurance in heat, cold, or dusty conditions.
• Navigating tight spots with 100+ ton loads in constantly changing environments.

Rewards:
