A single bridge girder erected on top of a runway structure makes up a single overhead crane, sometimes referred to as a single girder overhead crane. It is a well-liked option for many industrial applications because of its simplicity, economy, and versatility.
Here are some of the main characteristics and parts of a single overhead crane:
1. Single Girder: The crane's bridge is made up of a single, horizontal beam that spans the whole working space. The trolley and hoist are supported by the girder, allowing for runway movement at an angle.
2. Runway System: Installed on raised beams or columns are parallel rails that make up the runway system. A tram system that travels along the rails is used to move the crane along the runway. The necessary coverage area determines the runway's length.
3. Trolley System: The trolley is the device that moves along the bridge girder while transporting the hoist. It allows for the load's horizontal movement, enabling precise positioning inside the working area.
4. Hoist: The hoisting device attached to the trolley is known as a hoist. A motorised drum or chain is used to raise and lower the weight. Depending on the precise lifting needs, the hoist's capacity, speed, and control options can be altered.
5. Controls: To manage the crane's movement and hoisting operations, single overhead cranes are frequently fitted with a control pendant or a wireless remote control. Advanced elements like computerised control systems and automatic positioning may also be found in some cranes.
In many different industries, such as manufacturing, warehouses, workshops, and assembly lines, single overhead cranes are frequently utilised. They are intended for mild to moderate lifting capacities and are perfect for lifting and transporting loads within a constrained space.
Single overhead cranes have several benefits, such as:
- Cost-effective: Single girder cranes are an economical choice for many applications since they are often less expensive than double girder cranes.
- Single overhead cranes are versatile and can be used for a variety of lifting operations as well as carrying a variety of loads, including machinery, materials, and equipment.
- Installation is simple: Compared to more sophisticated crane systems, a single girder crane's design makes installation simpler and quicker.
- Compact design: Since single girder cranes have just one girder, they require less vertical space and are therefore appropriate for installations with restricted height.
It's vital to remember that a single overhead crane's lifting capacity and specifications depend on the model and maker. The best single overhead crane for a given application can be chosen with the assistance of a crane supplier or engineer.
