Your primary mission is to extract and move raw materials from the pit to the plant and manage product stockpiles. As a frontline leader in site safety, you are responsible for maintaining organized work areas, ensuring product quality, and directing the traffic flow of haul trucks to maximize production while strictly adhering to MSHA regulations.
KEY DUTIES AND RESPONSIBILITIES

  • Constant monitoring of conveyors, surge piles, and crushers to ensure safe operation and prevent blockages or equipment damage.
  • Conduct mandatory pre-shift and post-shift safety inspections on equipment, documenting all findings and reporting necessary repairs to supervisors or the maintenance shop.
  • Perform daily "walk-around" maintenance, including checking tire pressure, oil levels, and diesel fuel; greasing moving parts; and inspecting hoses for leaks.
  • Keep the loader cab and exterior clean and free of debris. Assist in general plant housekeeping, such as shoveling, sweeping, and clearing areas around hoppers.
  • Visually inspect materials during loading to ensure quality standards are met and prevent the mixing of different product grades.
