Proper maintenance is paramount for ensuring the longevity, reliability, and peak performance of a Hydraulic Conductor pulling machine, given the heavy loads and demanding environments they operate in:

• Adherence to Manufacturer's Manual: This is the foundational rule. Strictly follow all recommended service intervals and procedures for fluid changes, filter replacements, and inspections.

• Hydraulic System Management:

  • Fluid Quality: Regularly check hydraulic fluid levels and cleanliness. Change hydraulic oil and filters (return, pressure, suction) according to schedule. Contaminated or degraded fluid is the leading cause of hydraulic system failure.

  • Leak Detection: Daily inspect all hydraulic hoses, fittings, and cylinders for any signs of leaks, chafing, or damage. Address leaks immediately to prevent fluid loss and contamination.

• Engine Maintenance: Perform routine engine checks including oil levels, coolant, fuel filters, air filters, and fan belts. Ensure the engine is running smoothly without unusual noises or excessive smoke.

• Bullwheel/Drum Inspection:

  • OHTL Pullers: Regularly inspect bullwheel linings for wear, cracks, or grooves. Replace linings if significant wear is present to prevent conductor damage. Check bullwheel bearings for smooth rotation and excessive play.

  • underground Pullers: Inspect the pulling drum for damage, wear, or debris. Ensure the level winder mechanism operates smoothly.

• Brake System Check: For machines with braking systems, regularly inspect brake pads, discs, and hydraulic components for wear and proper function.

• Rope/Cable Path Inspection: Ensure all guides, rollers, and fairleads that the pulling rope or cable passes through are clean, free of debris, and in good condition to prevent abrasion and friction.

• Electrical System Check: Inspect wiring, connections, sensors, and the control panel for any signs of damage or loose connections.

• Structural Integrity: Periodically inspect the machine frame, chassis, anchoring points, and lifting points for cracks, bends, or corrosion.

• Cleanliness & Storage: Keep the machine clean, especially hydraulic components and control panels. Store the machine in a dry, protected environment when not in use to prevent weather-induced degradation.

• Calibration: Ensure that integrated tension sensors and dynamometers are regularly calibrated by certified technicians to maintain accuracy.
