Asphalt Plant Mechanic at O.K. Isokariari & Sons Nigeria Limited

Job Description

• The Asphalt Plant Mechanic is responsible for the continuous mechanical integrity of the asphalt production facility.
• Your primary focus is to troubleshoot, repair, and maintain heavy industrial machinery, including conveyors, dryers, elevators, and mixing units.
• You will be expected to minimize downtime through rigorous preventive maintenance and rapid emergency repairs in a high-temperature, fast-paced environment.

Responsibilities

• Preventive Maintenance (PM): Execute daily, weekly, and monthly PM schedules. This includes greasing bearings, checking oil levels in gearboxes, and inspecting wear liners.
• Heavy Mechanical Repair: Repair or replace defective parts such as conveyor belts, rollers, chain drives, sprockets, and pugmill paddles.
• Welding & Fabrication: Perform structural repairs and modifications using Arc, MIG, or Oxy-acetylene welding. Fabricate chutes or patches for worn-out steel components.
• Hydraulic & Pneumatic Systems: Maintain and troubleshoot high-pressure hydraulic pumps, cylinders, and pneumatic air compressors used for gate operations.
• Burner & Dryer Maintenance: Inspect and repair the aggregate dryer drum and burner systems to ensure efficient heating and fuel consumption.
• Safety Compliance: Strictly follow Lockout/Tagout (LOTO) procedures and ensure all machine guarding is in place to maintain a zero-accident workplace.

Requirements

• Experience: 4+ years of experience in heavy industrial maintenance. Prior experience specifically with Asphalt Plants (Batch or Drum) or heavy crushing plants is highly preferred.
• Technical Proficiency:
  • Expert-level welding and metal fabrication skills.
  • Deep knowledge of power transmission systems (gearboxes, couplings, and drive chains).
  • Proficiency in reading mechanical drawings and assembly blueprints.
  • Basic understanding of diesel engines (for auxiliary plant equipment).
  • Tool Usage: Skilled in using torque wrenches, dial indicators, hydraulic pullers, and various power tools.

Core Competencies:

• Diagnostic Ability: Can hear a failing bearing or identify a misaligned belt before it causes a total plant shutdown.
• Physical Resilience: Comfortable working at heights (on elevators/silos) and in confined, hot, or dusty spaces.
• Sense of Urgency: Understands that plant downtime translates to massive financial loss and lost paving time.
• Resourcefulness: Ability to perform "field repairs" to keep production moving safely until permanent parts arrive.
