Semi Gantry Crane
A semi-gantry crane is a material handling device that falls between a bridge crane and a gantry crane. Its unique structure features only one outrigger, with the other end supported on a crane beam in the factory building (the running track on the building is commonly called an overhead track, while the track on the ground is called a ground track). This crane combines advantages such as portability, high space utilization, and cost-effectiveness, making it suitable for various light and medium-duty lifting tasks. It is widely used in factories, warehouses, docks, and other locations, balancing operational efficiency and safety, and is especially suitable for space-constrained scenarios and small businesses.
Product Description
A semi-gantry crane is a uniquely structured and highly practical lifting device that integrates the structural features of bridge cranes and gantry cranes. It is suitable for various light and medium-duty lifting operations. Specific details are as follows:
Structural Composition
Composed of core components such as a support frame, cantilever beam, trolley, crane arm, hoisting mechanism, and electrical control system. These components work together to ensure stable and efficient lifting operations.
Structural Features
Equipped with only one outrigger, the other end rests on the crane beam of the factory building. The running track consists of an overhead rail (on the factory building) and a ground rail (on the ground), placing its structure between that of a bridge crane and a gantry crane.
Core Component Details
The support frame is built on the ground and constructed of steel, possessing sufficient strength and stability. The cantilever beam is a crucial component, available in truss and beam-plate structures, allowing for flexible selection based on specific lifting tasks.
Applicable Scenarios
Suitable for working in space-constrained environments, such as factories, warehouses, or production lines. Widely used for cargo loading and unloading, machinery maintenance, and various lifting operations in docks and factories.
Specifications
Available in light, medium, and heavy-duty versions to meet different load requirements. Lifting capacities range from hundreds of kilograms to over a thousand tons, adaptable to various load demands.
Safety Performance
Equipped with an advanced safety protection system, including weight detection and travel limiting functions, effectively ensuring the safety of operators and equipment.
Operational Efficiency
Utilizing a new generation of lifting structure and electrical control system, the crane ensures rapid response and precise operation, effectively improving lifting efficiency.
Cost and Maintenance
The equipment is relatively affordable, suitable for small businesses; its reasonable structural design allows for easy replacement and maintenance of parts, reducing downtime due to equipment failure.
Product Feature
Unique Structure
Positioned between a bridge crane and a gantry crane, it features only one outrigger, with the other end supported by a factory crane beam. The running track is divided into overhead rails (on the factory floor) and ground rails (on the ground), combining the advantages of both types of cranes.
Reasonable Structure
Composed of a support frame, cantilever beam, trolley, and auxiliary trolley, the support frame is a steel structure with sufficient strength and stability; the cantilever beam is available in truss and beam-plate structures, allowing for flexible selection based on the lifting task.
Lightweight and High Space Utilization
Lightweight and compact, it is particularly suitable for working in space-constrained environments (such as factories, warehouses, and production lines), effectively saving operating space. 4. Wide Application: Suitable for light and medium-duty lifting tasks, covering cargo loading and unloading, machinery and equipment maintenance, and various applications in docks and factories; available in light, medium, and heavy-duty versions, with lifting capacities ranging from hundreds of kilograms to over a thousand tons, adaptable to diverse load requirements.
Safe and Efficient
Equipped with an advanced safety protection system, including weight detection and travel limiting functions, ensuring the safety of personnel and equipment; a new generation of lifting structure and electrical control system enables rapid response and precise operation, improving work efficiency.
Affordable and Easy to Maintain
Compared to other types of cranes, it is more cost-effective, suitable for small businesses; its reasonable structural design allows for easy replacement and maintenance of parts, reducing equipment downtime and lowering maintenance costs.
Wheel Assembly Materials
Main Materials of the Product
1. Support Frame and Cantilever Beam: The core is made of high-quality carbon structural steel (mostly Q235B or Q355B). The support frame is welded steel structure. The cantilever beam is made of high-strength steel of corresponding specifications according to the structural type (truss structure, beam-plate structure), possessing sufficient strength, rigidity, and stability to withstand corresponding loads and external impacts during operation.
2. Mechanical Components (Trolley, Auxiliary Trolley, Lifting Mechanism): The trolley and auxiliary trolley frames are processed from high-quality steel, and the wheels are made of wear-resistant alloy steel to improve wear resistance and load-bearing capacity during operation. The core components of the lifting mechanism, such as the hook and gears, are made of high-strength alloy materials to ensure smooth transmission, safe load-bearing capacity, and extended service life.
3. Electrical Control System: Electrical components (controllers, sensors, cables, etc.) are made of high-quality electrical materials that meet industrial standards. Safety components such as weight detection and travel limiting use high-precision, high-reliability materials. The electrical control system has good anti-interference and aging resistance properties, ensuring accurate equipment response and safe operation.
4. Auxiliary components: The tracks (ceiling rails and ground rails) are made of wear-resistant steel with rust-proof and wear-resistant surface treatment; protective parts, connectors, etc. are made of high-quality steel with rust-proof coating to improve the equipment's corrosion resistance, adapt to different working environments, and extend the overall service life.
