With a professional team of technicians and experienced engineers in the fields of mechanical and electrical systems, Son Tung Company has successfully completed the maintenance service for the hydraulic and mechanical systems of 4 QC cranes.
The main repair and maintenance tasks included:
- Hoist cable tension system for QC cranes
- QC crane adjustment equipment
Son Tung carried out the replacement of control valves, cylinders, bearings, guide rails, sliding wheels, and other mechanical-electrical components. Additionally, we programmed the PLC controller and integrated automatic electrical devices such as linear valves, proportional pumps, load cell scales, and more into the existing crane system, ensuring it met the port’s specific requirements.
Working in harsh outdoor conditions with high lifting capacities, QC gantry cranes are prone to certain faults and malfunctions. Therefore, if these issues are not identified and addressed promptly, they can lead to serious consequences.
This equipment uses three-phase electrical power to unload materials, machinery, and containers at ports, loading or unloading goods from ships or onto the shore.
The QC crane consists of a structural frame, hoisting and lowering systems for the boom and cargo, container frame, grab bucket, magnetic plate, control systems, safety devices, and more.
