Main Features and Advantages of Overhead Crane
As a type of crane used in industrial environments for lifting and moving heavy loads horizontally across a workspace, an overhead crane machine typically consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of the crane, travels along the bridge. Below are the main features and advantages of overhead cranes:
Features
Main Features of Overhead Cranes
Bridge Structure
Single Girder: Features one main girder with a hoist trolley running on the lower flange of the girder. It is suitable for lighter loads and shorter spans.
Double Girder: Includes two girders with the hoist trolley running on rails mounted on top of the girders. This type is ideal for heavier loads and longer spans, providing greater lifting capacity.
Hoist Mechanism
Electric Hoists: The hoist, which does the actual lifting, is typically powered by an electric motor. It can be wire rope or chain-driven, depending on the load and application.
Trolley System: The hoist is mounted on a trolley that moves horizontally along the bridge, allowing for precise positioning of loads.
Control Systems
Pendant Control: A hand-held control device attached to the crane allows the operator to control the crane’s movements from the ground.
Remote Control: Wireless controls give operators the flexibility to move around while operating the crane, improving visibility and safety.
Cabin Control: For large cranes, an operator may sit in a cabin attached to the crane, providing a clear view of operations.
Runway System
Rail-mounted: The crane bridge travels on rails or tracks fixed on parallel runways, which are often mounted on the building’s columns.
Free-standing: For areas without appropriate building support, cranes can be installed on free-standing runway structures.
Safety Features
Limit Switches: Prevent the crane from moving beyond its designated range, protecting against collisions or overloading.
Overload Protection: A system that detects when the load exceeds the crane’s capacity and stops the lifting operation to prevent accidents.
Anti-sway Systems: Reduce the swaying of the load during lifting and movement, enhancing operational safety and precision.
Advantages
Advantages of Overhead Cranes
- Reduces Labor Costs and Long-lasting: By automating the lifting and moving processes, bridge crane machines reduce the need for manual labor, leading to significant cost savings over time. Built with robust materials, the crane equipment have a long lifespan and require minimal maintenance, resulting in lower long-term operational costs.
- Speeds Up Operations and Versatile Applications: Overhead bridge cranes can move loads quickly and efficiently, reducing the time needed for material handling and thereby increasing overall productivity in the workplace. They can be used in various industrial settings, from assembly lines to warehouses, providing versatile solutions for different material handling needs.
- Efficient Material Handling: Overhead cranes can handle very heavy loads, ranging from a few tons to hundreds of tons, depending on the design. This makes them ideal for industrial applications where heavy lifting is required. The cranes can move loads across large areas of a workspace, providing comprehensive coverage that forklifts or other lifting equipment cannot offer.
- Maximizes Floor Space and Flexible Installation: Since overhead travelling cranes operate above the working area, they do not take up valuable floor space, allowing for better utilization of the workspace. The cranes can be installed in existing facilities without major modifications to the floor plan, making them adaptable to different environments.
- Customization and Scalability: Overhead cranes can be tailored to meet specific operational needs, including special lifting capacities, spans, and speeds. They can be expanded or modified to accommodate changes in operational demands, making them a scalable solution for growing businesses.
