30 Ton Double Hook Container Gantry Crane Price
Introduction
A Container Gantry Crane, is a large-scale lifting machine commonly installed along quay fronts for container handling. It operates on vertical tracks for lifting motion and horizontal rails for long-distance travel, enabling efficient loading and unloading operations. The crane is composed of a robust gantry structure, lifting arm, slewing and luffing mechanisms, hoisting system, and traveling components. The gantry serves as the foundation, allowing longitudinal movement along the dock, while the luffing arm adjusts height to handle containers at various levels. Combined lifting and rotating mechanisms ensure precise positioning and rapid container transfer, making it an essential piece of equipment in modern port logistics.
Technical Advantages
High Efficiency: Container gantry cranes are engineered for rapid loading and unloading operations. Their powerful hoisting mechanisms and precise control systems enable continuous, high-speed container handling, significantly improving port throughput and reducing vessel turnaround time.
Exceptional Precision: Equipped with advanced electronic control and positioning systems, the crane ensures accurate lifting, alignment, and placement of containers. This precision minimizes handling errors and damage, ensuring smoother logistics operations.
Strong Adaptability: Modern container gantry cranes are designed to accommodate containers of various sizes and weights, including 20ft, 40ft, and 45ft units. They can also operate reliably under diverse environmental conditions such as strong winds, high humidity, and extreme temperatures.
Superior Safety: Multiple safety features—such as overload protection, emergency stop systems, wind-speed alarms, and anti-collision devices—are integrated to guarantee safe operation. The structure uses high-strength steel to ensure long-term stability under heavy loads.
Intelligent Control: Automation and remote-control capabilities allow for real-time monitoring and fault diagnostics, enhancing operational safety and reducing manpower requirements.
Easy Maintenance and Longevity: Modular design and durable components simplify maintenance procedures, extend service life, and reduce downtime, ensuring consistent reliability throughout the crane’s lifespan.
How to Operate a Container Gantry Crane
Operating a container gantry crane involves a series of coordinated and precise steps to ensure efficiency and safety throughout the lifting process.
1. Positioning the Crane: The operation begins by positioning the heavy duty gantry crane above the container that needs to be lifted. The operator uses the control cabin or remote system to maneuver the crane along its rails, ensuring alignment with the container’s location.
2. Engaging the Spreader: Once properly aligned, the spreader is lowered using the hoisting mechanism. The operator adjusts its position so the twist locks on the spreader engage securely with the container’s corner castings. The locking process is confirmed through sensors or indicator lights before lifting begins.
3. Lifting the Container: The operator activates the hoist system to lift the container smoothly off the ground, truck, or vessel deck. The system maintains balance and stability to prevent sway during elevation.
4. Transferring the Load: The trolley then moves horizontally along the bridge girder, carrying the suspended container to the desired drop-off point—either a storage yard, truck, or stacking area.
5. Lowering and Releasing: Finally, the container is carefully lowered into position. Once placed securely, the twist locks disengage, and the spreader is lifted away, completing the cycle safely and efficiently.
