Core Responsibilities

Primary Functions

Execute the installation, alignment, and commissioning of new industrial machinery and heavy equipment according to complex blueprints, schematic drawings, and engineering specifications.
Perform comprehensive preventive and predictive maintenance tasks on mechanical systems, including pumps, compressors, conveyors, gearboxes, and production machinery, to ensure operational reliability.
Systematically diagnose and troubleshoot sources of mechanical malfunction or failure in hydraulic, pneumatic, and power transmission systems using diagnostic tools and logical problem-solving.
Dismantle, repair, and reassemble machinery and equipment, replacing defective parts such as bearings, seals, gears, and motors with precision and care.
Fabricate and repair machine parts using a variety of shop equipment, including lathes, milling machines, grinders, and drill presses, when replacement parts are not readily available.
Perform advanced rigging, lifting, and hoisting operations to safely move, position, and secure heavy machinery and components during installation or repair.
Conduct precision alignment of rotating equipment, such as motors, pumps, and fans, using laser alignment tools and dial indicators to minimize vibration and wear.
Read and interpret intricate technical manuals, blueprints, and isometric drawings to understand equipment assembly, operation, and repair procedures.
Perform various welding tasks (e.g., SMAW, MIG, TIG) and cutting operations to fabricate or repair structural components, guards, and equipment frames.
Install and maintain power transmission systems, including belts, chains, sprockets, and couplings, ensuring proper tension and alignment.
Service and repair fluid power systems by replacing hydraulic and pneumatic lines, cylinders, valves, and pumps.
Monitor equipment operation through vibration analysis, thermography, and other predictive maintenance (PdM) techniques to identify potential failures before they occur.
Maintain accurate and detailed maintenance logs, work orders, and repair reports using a Computerized Maintenance Management System (CMMS).
Adhere strictly to all plant safety and environmental regulations, including Lockout/Tagout (LOTO), confined space entry, hot work, and fall protection procedures.
Operate mobile equipment such as forklifts, scissor lifts, and boom lifts to access and transport materials and machinery.
Grout and anchor machinery bases and frames to ensure stable and level installation.
Overhaul and rebuild major equipment components during planned shutdowns and turnarounds.
Perform pipefitting tasks, including cutting, threading, and installing piping for various fluid and gas systems.
Calibrate and adjust machinery components and instrumentation to meet production specifications and quality standards.
Respond to emergency breakdown calls in a timely and effective manner to minimize production downtime and restore equipment to a safe operational state.

Secondary Functions

Mentor and provide on-the-job training and guidance to apprentices and junior maintenance personnel.
Participate in continuous improvement initiatives and root cause analysis (RCA) meetings to prevent recurrence of equipment failures.
Assist in the management and organization of the spare parts inventory, identifying critical components and recommending appropriate stock levels.
Liaise with external contractors, service technicians, and parts vendors to coordinate specialized repairs or source necessary components.
