Product Description

400ton hydraulic gantry crane
Hydraulic gantry cranes are primarily utilized in space-limited environments for heavy lifting tasks, including the installation of large transformers, ship propellers, and heavy industrial equipment within workshops.

The system comprises four jacking units, a hydraulic station, mobile spreaders, beams, and wireless remote control. Each unit offers a carrying capacity of 100 tons. The system employs a closed-loop control method with variable speed motors to ensure precise synchronization during lifting and traveling operations.

Features and Advantages

Hydraulic Pump Station
Features a centralized design where one hydraulic station powers four lifting units. Variable speed control allows for flexible adaptation to operational needs, with synchronization maintained via a centralized control system.

Advanced Lifting Unit
Includes jacking cylinders, driving motors, and planetary reducers. Key safety features include dual locking devices (hydraulic and mechanical cam locking). A spherical roof at the top allows for small displacement corrections.

Main Beam and Track
Constructed for high durability with lower deflection (< 1/750). Features C5 anti-corrosion coating and canopy protection for outdoor use. All components undergo shot blasting for superior paint adhesion.

Frequently Asked Questions

1. What are the primary applications for this hydraulic gantry crane?

It is primarily used for heavy lifting in restricted spaces, such as installing large transformers, ship propellers, and moving massive equipment in workshops.

2. How is lifting synchronization ensured between the legs?

Each leg is equipped with height sensors. The PLC control system monitors real-time feedback and automatically adjusts the oil flow to ensure precise synchronization.

3. What safety locking mechanisms are included?

The lifting units feature a dual locking system comprising hydraulic locking and mechanical cam locking to ensure maximum reliability and safety during operation.

4. Can the load position be adjusted after lifting?

Yes, with the optional mobile lifting gear, the load can be moved along the direction of the crossbeam for precise three-dimensional positioning.

5. How does the crane handle environmental corrosion?

The crane is treated with a C5 protection coating and includes rain/sun covers for the control panels, making it suitable for harsh or outdoor environments.

6. What is the maximum lifting capacity available?

Standard configurations range from 100 to 1200 tons, providing solutions for a wide variety of heavy-duty industrial lifting requirements.
