A rigorous inspection and preventive maintenance program plays a decisive role in enhancing operational safety, equipment availability, and crane productivity for heavy industrial machinery operating under intense continuous duty cycles.
Rubber-Tired Gantry (RTG) cranes are vital assets in modern container logistics. Weighing upwards of 120–150 metric tons unladen, RTG cranes experience uneven structural stresses depending on container block layouts, handling throughput, tropical monsoon humidity, salty marine air, and operational age. Consequently, each RTG crane requires a customized, data-driven maintenance regimen rather than a generic one-size-fits-all approach.
With over 35 years of specialized maritime engineering heritage, Tan Cang Technical Services Joint Stock Company (Tan Cang Tech) is the leading provider of technical assurance, routine servicing, and major overhauls for container cranes in Vietnam.
Core Modules of Tan Cang Tech RTG Maintenance Programs
- Mechanical & Hoist System Audits: Complete inspection of main hoist wire ropes (discard criteria ISO 4309), wire sheaves, drums, planetary travel gearboxes, and multi-disc hydraulic brakes.
- Gantry Wheel, Steering & Tire Health: Ultrasonic testing of wheel bogie pins, laser alignment of wheel tracks, hydraulic steering pressure calibration, and tire wear profiling.
- Spreader & Twistlock Inspection: Dynamic testing of telescoping chains, hydraulic cylinder seals, proximity sensors, and magnetic particle non-destructive testing (MPI) of twistlock pins.
- Electrical Drives & PLC Automation: Infrared thermography of Variable Frequency Drive (VFD) panels, cleaning of PLC controllers, megger testing of electric motors, and calibration of load cells.
- Structural Integrity & Corrosion Protection: Structural weld inspection, ultrasonic thickness gauging of sill beams, and marine-grade anti-corrosive coating restoration.
Partnering with Tan Cang Tech guarantees container terminal operators maximized equipment uptime, predictable operating budgets, and extended crane operational lifecycle.
