Product Description

Product Description

Truss Girder Gantry Crane With Two Hoists

The truss girder gantry crane is a robust, reliable lifting solution designed for outdoor and heavy-duty applications. Featuring a truss-style girder, this crane provides enhanced wind resistance and structural stability, making it ideal for use in ports, construction sites, and other environments exposed to moderate to high wind loads. The truss girder design offers superior strength, rigidity, and reduced weight compared to traditional crane designs, ensuring a stable, efficient, and safe operation even in challenging working conditions.

This crane comes equipped with two hoists, providing versatility and enhanced load-handling capabilities, whether lifting independently or in tandem. The standard material is Q235B steel, offering a reliable, cost-effective solution, with Q355B steel available as an upgrade for more demanding applications.

(1) Features

• Truss-style Girder Design: Provides superior wind resistance, strength, and stability while minimizing weight for easier maneuverability and reduced wind load.
• Dual Hoists: The crane is equipped with two hoists, offering flexibility for lifting loads independently or in tandem for improved operational efficiency and safety.
• Euro-Style Hoists: Available as an upgrade option, these hoists are designed for high-duty operations, offering smooth, efficient, and precise lifting capabilities, ideal for heavier and more demanding loads.
• Flexible Control Options: Hoists can be operated in tandem for synchronized lifting or separate control for independent operation, offering versatility in managing different load configurations.
• Durable Construction: Constructed with Q235B steel as the standard material, this crane is built to last, offering strong resistance to wear and corrosion. Q355B steel is available as an upgrade for more demanding environments.
• Weather-Resistant: Engineered to withstand moderate to high wind loads, providing stability and safety in exposed locations.

(2) Making an Informed Purchase Decision

When choosing a truss girder gantry crane, it's essential to evaluate the specific needs of your operation. Consider the maximum lifting capacity, type of loads, and the environmental factors where the crane will be used. If your site is exposed to moderate to high winds, the truss girder design offers enhanced resistance and stability compared to other types of girders, making it ideal for such conditions.

For greater operational flexibility, consider the dual hoist system, which allows for simultaneous or independent lifting operations. If your work requires high precision and heavy lifting capabilities, the euro-style hoist option provides smoother operation and higher work duty cycles.

Finally, assess the crane's control options-whether tandem control or separate control will best suit your operational needs. Shanghai Hexin's team of specialists is ready to guide you in selecting the perfect solution for your lifting requirements, ensuring optimal performance and safety.

Product Structure

Understanding the Structure of a Single Girder Gantry Crane

The structure of a single girder gantry crane is a strong and efficient system designed for lighter to medium-duty lifting tasks. Understanding its key components, such as the main girder, legs, hoist, and end trucks, helps operators maximize the crane's performance, ensure smooth operation, and extend its service life. A clear grasp of the crane's structure enables users to operate with confidence, minimize maintenance needs, and enhance overall safety and productivity.

Gantry Structure (Main Beams and Legs)

The gantry structure forms the framework of the crane, providing the strength and stability required to lift and move heavy containers. The main components of the gantry structure include:

Main Beams (Girders): These horizontal beams span the width of the crane and support the weight of the trolley, hoisting system, and the container being lifted. The main beams are designed to withstand significant loads, often constructed from high-strength steel.

Legs (Columns): The legs support the main beams and connect them to the ground or rail system. In a rail-mounted gantry container crane, these legs run on tracks along the length of the crane's working area. For a rubber-tired gantry container crane, the legs are equipped with rubber tires, enabling mobility within the container yard.

Trolley and Hoisting Mechanism

The trolley is a mobile platform that runs along the length of the main beams. It houses the hoisting mechanism, which is responsible for lifting and lowering containers. The hoisting mechanism includes a system of ropes, pulleys, and a motor-driven hoist drum that enables the lifting operation.

Hoist Drum and Ropes: The hoist drum winds and unwinds the steel ropes that are attached to the spreader, controlling the vertical movement of the container. High-tensile ropes are used to ensure the safety and durability of the hoisting system.

Trolley Motor: The trolley is powered by motors that allow it to move horizontally along the crane's main beams, positioning the hoist directly above the container being lifted or placed.

End Truck

Located at each end of the crane, the end trucks enable the gantry crane to travel along the rails using a set of wheels that run smoothly on the tracks. Depending on the crane's capacity, each end truck can be equipped with 2, 4, or 8 wheels, ensuring optimal stability and performance.

 

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
3. Electric Protective Devices
4. Emergency Stop System
5. Voltage Lower Protection Function
6. Current Overload Protection System
7. Rail Anchoring
8. Lifting Height Limit Device

Of course, we also offer a customized service.To provide you with the most accurate and tailored design solution, please share the following details:

1.Lifting Capacity:
Please specify the maximum weight your crane needs to lift. This critical information enables us to design a system that can handle your loads safely and efficiently.

2.Span Length (Rail Center to Rail Center):
Provide the distance between the centers of the rails. This measurement directly impacts the overall structure and stability of the crane we'll design for you.

3.Lifting Height (Hook Center to Ground):
Indicate how high the hook needs to reach from the ground level. This helps determine the appropriate mast or girder height for your lifting operations.

4. Rail Installation:
Have you already installed the rails?If not, would you like us to supply them?Additionally, please specify the required rail length. This information helps us plan the complete setup for your crane system.

5. Power Supply:
Specify the voltage of your power source.Different voltage requirements affect the electrical components and wiring design of the crane.

6. Working Conditions:
Describe the types of materials you'll be lifting and the ambient temperature. These factors influence the choice of materials, coatings, and mechanical properties for the crane to ensure its durability and optimal performance.

7. Workshop Drawing/Photo:
If possible, sharing a drawing or photo of your workshop would be highly beneficial. This visual information helps our team better understand your space, layout, and any potential obstacles, allowing us to tailor the crane design more precisely to your site.
