Double Girder High Capacity Gantry Crane

Product Specifications

Key Features & Benefits

Robust Double-Girder Structure

The dual main beam design enhances load-bearing capacity and structural rigidity, enabling safe lifting of large-tonnage heavy loads without deformation. This design ensures long-term operational durability even in high-intensity working environments.

Low Headroom Optimization

With low headroom design, the distance between the hook and the main beam is minimized, maximizing the effective lifting height and utilizing vertical space efficiently—critical for outdoor yards with height restrictions.

High-Precision Variable Frequency Control

Equipped with a VFD motor, the crane offers smooth speed adjustment, reducing load sway during lifting and horizontal movement. Precise positioning ensures accurate placement of heavy components, improving work efficiency and reducing material damage.

Superior Safety Configuration

Integrated safety features include overload protection, lifting limiters, emergency stop buttons, and long-life brakes. The IP55/IP65 protection class shields internal components from dust, moisture, and harsh weather, ensuring operational safety in extreme industrial conditions.

Cost-Effective & Space-Saving

The gantry structure eliminates the need for overhead building support, reducing construction costs for workshops or yards. Its modular design simplifies transportation and installation, lowering overall project investment.

Application Scenarios

Ideal for loading, unloading, and stacking bulk materials such as pipes, steel coils, and construction materials in open-air storage facilities. Handles heavy cargo containers, marine equipment, and oversized components, supporting efficient logistics and shipping operations. Facilitates the assembly and movement of large machinery parts (e.g., engine blocks, industrial boilers) in manufacturing plants. Used in power plants, steel mills, and smelters for lifting raw materials, finished products, and maintenance equipment. Suitable for assembling wind turbine components, bridge segments, and other oversized structures requiring precise, heavy-duty lifting.

Installation & Maintenance Tips

Professional Modular Installation

Follow the manufacturer’s guidelines for rail alignment and beam assembly. Ensure the ground rails are level and stable to prevent operational vibration. It is recommended to hire certified technicians for installation to guarantee safety and performance.

Regular Safety Inspections

Conduct weekly checks on brakes, limiters, and steel cables for wear or damage. Monthly inspections should focus on electrical systems, motor performance, and structural integrity.

Lubrication & Wear Monitoring

Apply high-quality lubricants to gears, bearings, and trolley wheels every 3 months. Monitor the condition of steel ropes and replace them immediately if fraying or corrosion is detected.

Weather Protection for Outdoor Use

For IP55 models, install protective covers for electrical control boxes in rainy or dusty environments. Regularly clean the crane’s surface to remove debris and prevent corrosion.
