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.

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.
  • Bridge Part of Overhead Crane (Colored Part)

  • 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.
  • hoist
