What Is An Overhead Crane？

An overhead crane features a bridge-shaped main structure frame. Therefore, it is also known as a bridge crane. It consists of a bridge frame that spans the workshop or work areas and columns or brackets that support the track. It also includes a running mechanism that carries a lifting trolley. The trolley can work with an electric wire rope or a chain hoist to lift.

How Does An Overhead Crane Work?

The horizontal movement of the crane, the longitudinal movement of the trolley, and the vertical lifting of the hook together form the three-dimensional working space. The operator controls the coordinated actions of various mechanisms to achieve precise handling of goods in three-dimensional space. This design enables it to cover a large area of ​​work within a limited ground space, thus improving space utilization.

  • Bridge structure: It bears the weight of the entire crane. Usually made of welded steel, it has sufficient strength and stability.
  • Crane running mechanism: Drives the bridge to move horizontally along the fixed track to cover the entire work area.
  • Trolley running mechanism: Mounted on the bridge, it can move longitudinally and is responsible for the precise positioning of the hook.
  • Lifting mechanism: Wire ropes or chains helps realize the vertical lifting of goods.
  • Control system: Includes an operating console, remote control or automation system for precise control.

What Is An Overhead Crane Used For?

An overhead crane has high efficiency, flexibility, large lifting capacity, durability, safety and high space utilization. Therefore, it is suitable for diverse industrial scenarios and environments.

  • Industrial workshop: In the machinery manufacturing workshop, an overhead crane can lift large machine tool parts, blanks, finished products, etc. It also cooperates with the production line to complete the transfer and assembly of materials. For example, it lifts heavy parts such as steel molds in the plastic injection molding manufacturing workshop. In the metallurgical workshop, it can lift high-temperature or heavy materials such as ladles, ingots, and steel. It can meet the material handling needs during smelting and rolling.
  • Warehousing and logistics: In large warehouses and logistics centers, a bridge crane stacks and moves containers, pallets and other goods. Especially in automated stereoscopic warehouses, it can combines automated control systems to achieve efficient storage and turnover of goods.
  • Power industry: In power plants, it installs and repairs large equipment such as steam turbines and generators. And it lifts heavy power materials such as transformers and cables. In hydropower stations, it can lift turbine parts, gates, etc..
  • Building materials: In prefabricated component factories, concrete prefabricated panels, steel structure components, etc. are lifted. At the bridge construction site, it cooperates with the lifting of large components such as bridge sections and steel box girders.
