JOB SUMMARY
The Equipment Operator is a foundational role responsible for the safe and efficient operation of mobile heavy equipment used in the extraction, transportation, and processing of aggregate materials (sand, gravel, and crushed stone).
As a key contributor to the production cycle, the Operator ensures that raw materials move seamlessly from the pit to the plant and that finished products are managed effectively in stockpiles. Beyond machinery operation, this role is deeply integrated into the site's maintenance and safety culture, requiring a "Safety First" mindset and a willingness to perform cross-functional duties, including manual labor and plant housekeeping-to maintain an elite operational environment.
KEY DUTIES AND RESPONSIBILITIES
Safely operate entry-to-mid-level mobile equipment, including but not limited to Haul Trucks (off-road), Water Trucks, and Front-End Loaders (e.g., CAT 980/988 series).
Transport raw materials from the extraction pit to the primary crusher and move finished aggregate products from the plant to designated stockpiles.
Maintain the integrity of product stockpiles by ensuring materials are separated correctly to prevent contamination.
Operate water trucks to manage dust control on haul roads and utilize equipment to maintain berms, ramps, and safe traffic flow throughout the facility.
Conduct rigorous daily inspections of vehicle systems (brakes, steering, fluids, tires, and gauges) to identify potential hazards or mechanical issues.
Perform routine PM tasks, including greasing moving parts, checking oil levels, cleaning cabs, and assisting mechanics with minor repairs (e.g., replacing idlers, belts, or bearings).
Use Standard Operating Procedures (SOPs) to identify and report equipment malfunctions or unusual sounds to the maintenance team immediately to minimize downtime.
Operate all machinery in strict accordance with MSHA (Mine Safety and Health Administration) regulations and Martin Marietta's internal safety policies.
Participate in the "Guardian Angel" safety program by identifying "near miss" hazards, wearing all required PPE, and looking out for the safety of coworkers and visiting contractors.
Ensure all operations comply with environmental standards, specifically regarding dust control and spill prevention in the yard.
When not operating equipment, assist in plant operations which may involve manual shoveling, sweeping around conveyors, cleaning under crushers, and general site cleanup.
Maintain constant contact with plant operators and other drivers via CB radio or hand signals to coordinate safe movement and material flow.
Accurately complete daily production logs, maintenance reports, and safety forms.
