Electric Overhead Crane & Steel Structure Solution
In the contemporary construction landscape, steel structures are gaining increasing popularity. Our company offers a diverse range of steel structure products, including steel structure workshops, steel structure factory, steel structure warehouse, etc.
These steel structures, often requiring overhead cranes for heavy lifting, come in two main categories: light steel structure and heavy steel structure, catering to various customer needs. The light steel structure, suitable for low-load-bearing buildings, typically utilizes H-beams in its construction. On the other hand, heavy steel structures are designed to withstand relatively substantial loads. The choice between these structures depends on factors such as the intended load and crane requirements. The overhead crane and steel structure combined as crane steel structure.
Furthermore, our steel structure warehouses come in different spans, offering flexibility in design. Single span structures have two rows of steel columns supporting the roof, while double span buildings are created by combining two single span structures. Our company also provides customization options, allowing customers to tailor the structure to their specific requirements. Feel free to engage with our experts for a personalized consultation to ensure an ideal product for your projects.
A steel structure factory is characterized by its main load-bearing components being composed of steel, including columns, beams, wind columns, purlins, etc. The growing popularity of steel structure workshops, steel structure factories and steel structure warehouses can be attributed to their numerous advantages.
These workshops can be customized to meet specific needs, offering a cost-effective solution. Whether you require a single span, double span, or multi-span steel structure workshop, our offerings are designed to accommodate diverse project requirements. We also provide steel grid structure solutions.

Main Components of of Electric Overhead Crane
Electric overhead cranes consist of several main components that work together to facilitate safe and efficient material handling operations. Here are the key components typically found in an electrical overhead crane:
- Bridge: The bridge is the main horizontal component of the crane that spans the width of the working area. It consists of a girder or beam supported by end trucks on either side. The bridge carries the hoist and trolley, allowing them to traverse along the length of the runway.
- Hoist: The hoist on the overhead electric hoist crane is responsible for lifting and lowering loads. It comprises an electric motor, gearbox, and drum or chain mechanism. The load is attached to a hook or lifting attachment that is raised or lowered using the hoist. Electric hoists offer precise control over lifting operations.
- Trolley: The trolley is a wheeled mechanism that runs along the bridge. It supports the hoist and allows it to move horizontally across the span of the bridge. The trolley is typically powered by an electric motor and can be operated independently or synchronized with the bridge movement.
- Runway: The runway consists of rails installed along the length of the working area. It provides a track for the bridge and trolley to move along. The runway is usually supported by structural beams or columns and must be designed to withstand the weight of the crane and its loads.
- End Trucks: End trucks are located at both ends of the bridge and support its structure. They house the wheels or rollers that run along the runway rails. End trucks often contain drive motors that power the bridge movement, allowing the crane to traverse the runway.






Overall, electric overhead travelling cranes combine these key components to provide reliable and precise material handling solutions in various industrial environments. Understanding the function and interplay of these components is essential for operators to operate the crane effectively while maintaining safety standards.
Applications of Electrical Overhead Crane
Electrical overhead cranes find extensive applications in various industries and environments due to their versatility, lifting capacity, and efficiency. Here are some common applications of electrical overhead cranes:
- Warehousing and Logistics: In warehousing and logistics facilities, electric bridge cranes are employed for efficient material handling tasks. They are utilized for loading and unloading goods from trucks, organizing and stacking pallets or containers, and transferring materials within the warehouse. Electric overhead cranes help optimize storage capacity and streamline inventory management.
- Construction Sites: Construction sites often require heavy lifting and precise placement of materials and equipment. Electrical overhead cranes provide the necessary strength and control to lift and move construction materials like steel beams, precast concrete components, and machinery. They enable efficient construction processes and enhance worker productivity.
- Foundries and Steel Mills: Foundries and steel mills require robust equipment for handling molten metal, heavy molds, and raw materials. Electrically operated overhead travelling cranes with specialized features for high-temperature environments are utilized in these industries. They enable the safe transportation of hot metal ladles, molds, and ingots throughout the production process.


These are just a few examples of the wide range of applications for electric bridge cranes. Their adaptability, lifting capacity, and flexibility make them an indispensable tool in numerous industries where heavy lifting and precise material handling are required.
