Product Description

Product Description

                                                                                      Single Girder Semi Gantry Crane

A semi-gantry crane is a type of overhead crane with a unique structure. One side of its legs is mounted on wheels or rails, allowing it to move freely, while the other side is supported by a runway system connected to the building columns or the side wall of the building structure. This design offers significant advantages in space utilization by effectively saving valuable floor and workspace. As a result, it is particularly well-suited for environments with limited space, such as indoor workshops. Semi-gantry cranes are versatile and can be used in various operational settings, including heavy fabrication applications and outdoor yards (such as rail yards, shipping/container yards, steel yards, and scrap yards).

Additionally, the design allows forklifts and other motorized vehicles to work and pass underneath the crane without obstruction.

Features

	Advantages
Structure	Utilizes and existing building structure as one side of support, saving floor space and reducing costs.
Application	Suitable for both indoor and outdoor settings, versatile for various environments.
Flexibility	Provides larger floorspace for forklifts, trucks, or other machinery to move freely around the site.
Cost	lower material and shipping costs compared to a full gantry crane.
Maintenance	Easy to maintain, with fewer components requiring attention.

Making an Informed Purchase Decision

Before making a purchase decision, it is crucial to have a clear understanding of your workload, lift height, and other specific operational needs.

With years of professional expertise, Shanghai Hexin is equipped with a team of specialists dedicated to helping you select the most suitable lifting solution tailored to your objectives. choosing the right girder form, lifting mechanisms, and components is vital. This ensures optiomal operational efficiency while helping you manage costs effectively, keeping them within your budget.

This single-girder semi-gantry crane is ideal for light to medium-duty applications, offering a cost-effective solution with reduced material and shipping costs.

However, it does have certain limitations. These include constraints in workload capacity, span, and hook height. Additionally, incorporating special features, such as walkways and cabins, can present challenges. Nevertheless, for operations where these limitations are not restrictive and cost-efficiency is a priority, this crane remains a practical and reliable option.

If you're considering investing in a new semi-gantry crane system and require a detailed quote, or if you're seeking expert advice on the optimal lifting solution for your specific operations, don't hesitate to contact us. Our dedicated team is always on standby, ready to understand your requirements and provide tailored solutions that perfectly meet your needs.

Which lifting mechanism should you choose? A hoist or a winch?

	Hoist	Winch
Load Capacity	Best suited for light to medium loads	Wide range, ideal for extremely heavy loads-maybe overkill for light loads
Lifting Speed	Typically slower than a winch	High upper limit, but challenging to achieve very slow and precise movements
Duty Cycle	Suitable for light to medium duty; heavy work duty may reduce lifespan	Perfect for continuous high-duty jobs; overqualified for slow, light-duty tasks
Precision & Control	Preferred for high precision, offering better load positioning	Harder to achieve fine precision; customization is possible at extra cost
Space & Installation	Compact in design, simple installation	Larger size, complex setup, but allows more room for customization
Cost	Lower initial and maintenance cost; may increase with customization	higher cost in general

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.

.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.

.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.
