This crane is built to offer smooth and reliable operation even in the most demanding industrial settings.

(1) Features

• Heavy Duty Lifting Capacity: Capable of handling a wide range of heavy loads, making it suitable for large-scale operations and complex lifting applications.

• Double Girder Design: Ensures superior rigidity, load-bearing capacity, and stability for lifting and moving heavy loads across long distances.

• Winch Mechanism: The winch offers high torque and robust lifting capabilities, ideal for lifting heavy loads with powerful and reliable lifting performance.

• High Lifting Height: Perfect for high-lift applications in industries such as construction, shipyards, and manufacturing, where vertical clearance is essential.

• Versatile Control Options: Choose from pendant control, radio remote control, or the cabin control upgrade for added convenience and ergonomic operation, especially in larger or more complex work environments.

• Work Duty: Suitable for A5 to A7 work duty cycles, making it ideal for medium to heavy-duty operations in demanding industrial settings.

• Durability and Power: The winch mechanism ensures reliable performance and high load handling in tough industrial environments, such as steel processing and large-scale material handling.

• Safety Features: Equipped with overload protection, limit switches, and emergency stop systems for safe operation in high-risk environments.

(2) Making an Informed Purchase Decision
 

When selecting the Double Girder Gantry Crane with Winch, it is crucial to evaluate the lifting capacity, required load distribution, and environmental factors. This crane is built for industries where heavy-duty lifting and high load capacities are required, such as steel manufacturing, construction, and shipyards.

The winch mechanism offers significant advantages in handling large and heavy loads with a powerful and reliable lifting system, but it may not offer the same precise vertical movement as a hoist. If your application demands fine control or smooth vertical lifting, a hoist may be the better option. However, if your operations require high lifting capacity, consistent power, and durability under heavy-duty conditions, a winch will provide you with the necessary strength and reliability.

Additionally, the cabin control upgrade offers operators enhanced visibility, ergonomics, and convenience, particularly in larger work environments with more complex operational demands. At Shanghai Hexin, our team of specialists is ready to help you determine the best lifting solution for your project.

Product Structure

Understanding the Structure of a Double Girder Gantry Crane

A double girder gantry crane features two parallel girders that span the width of the crane, providing superior strength and load-bearing capacity. This structure is commonly used for heavy-duty lifting tasks where stability and high load capacities are essential. The crane includes key components such as the main girders, end trucks, hoist trolley, and wheels that travel along rails or tracks mounted on the ground or supporting structure.
The double girder design provides enhanced rigidity, making it ideal for lifting and transporting heavy loads over long spans, commonly used in industries like steel mills, shipyards, and heavy manufacturing plants. Understanding these structural elements helps in selecting the right crane for your lifting needs.

Gantry Structure (Main Girders and Legs)

The gantry structure forms the crane's framework, providing strength and stability for heavy lifting. Key components include:

Main Girders (Beams): These horizontal beams span the crane's width, supporting the hoist and load. The double girder design enhances load-bearing capacity and stability, typically constructed from high-strength steel.

Legs (Columns): The legs support the girders and connect the crane to the ground or rails. For rail-mounted cranes, the legs feature wheels that move along tracks, while in some configurations, they may include adjustable heights for specific lifting needs.

Trolley and Hoisting Mechanism

The trolley is a mobile platform that travels along the main girders, supporting the winch system used for lifting heavy loads. The winch mechanism includes components that provide powerful lifting capabilities.

Winch and Ropes: The winch utilizes high-tensile ropes to lift and lower loads, with the rope winding and unwinding around a drum to control vertical movement. The winch is designed to handle heavy-duty lifting tasks with precision and reliability.

Trolley Motor: Powered by motors, the trolley moves horizontally along the main girders, positioning the winch directly above the load to ensure efficient lifting and placement.

Traveling Mechanism

The traveling mechanism allows the double girder gantry crane to move horizontally along its track or rails. It features motorized end trucks mounted at the base of the crane's legs, which are equipped with wheels.

The number of wheels can be customized to meet the specific needs of the customer, ensuring optimal load distribution and smooth movement. These end trucks are powered by motors, enabling precise and efficient travel across the work area for effective load handling over long distances.

Hook

Our cranes are equipped with a variety of lifting tools designed for diverse applications.

The hook is ideal for general lifting tasks, providing a reliable connection for lifting and moving loads safely.

The grab bucket is perfect for handling bulk materials, allowing for efficient and secure lifting of loose or granular items.

Additionally, we offer a range of other specialized lifting tools tailored to meet specific operational needs, ensuring maximum efficiency and safety for your lifting operations.

Controls 

Control boxs are typically mounted on the crane or hoist and the pendant or remote console allows the operator to run the crane. The controls operate the drive and hoist motors, and can control Variable Frequency Drives (VFDs) to control hoist speed for precise load positioning.

Power Supply System

Insulated conductor bars, festoon systems (flat cables), or cable reels bring power to the crane.

Safety Devices: To ensure the seamless operation of the crane and to prevent potential personal injuries or mechanical failures, our safety apparatus
goes beyond basic electric protective devices or alarm bells. It includes a comprehensive range of essential equipment, as detailed below:

1. Overload Limit Switch
2. Rubber Buffers
