• Capacity: Ranges from 5 to 450 tons, with some models capable of lifting up to 250 tons[2][5].
• Span: Typically spans from 10.5 to 31.5 meters[1][2].
• Lifting Height: Can vary from 6 to 24 meters[1][2].
• Speeds:
• Lifting speed: 2.1 to 11.5 m/min[2].
• Trolley speed: 27 to 40 m/min[2].
• Crane speed: 42 to 75 m/min[2].
• Work Duty: Generally classified under A3 to A7 work duty[1][2].

Key Components of Overhead Cranes

Bridge Beam

• The bridge beam is the main structural component that spans the runway. Single girder cranes use one I-beam, while double girder cranes use two[5].

Hoist/Trolley

• The hoist/trolley is the lifting mechanism that moves along the bridge beam. In single girder cranes, it is usually an under-hung style trolley. In double girder cranes, the hoist/trolley unit traverses across rails mounted atop the two bridge girders[3][4].

Runways

• Runways are the tracks on which the crane travels. They can be part of the building structure or a freestanding system[4].

Mounting Types

Top Running Cranes

• These cranes are mounted on top of the runway beams, which can be part of the building structure or a freestanding system. Top running cranes offer greater lifting height and are easier to install and service[3][5].

Under Running Cranes

• These cranes are mounted below the runway beams. They are suitable when headroom is a major issue but offer less lifting height compared to top running cranes[3][5].

Specialized Overhead Cranes

European Style Double Girder Cranes

• These cranes adopt European-style design structures, characterized by light weight, small wheel pressure, and reliable performance. They are often used in heavy-duty applications and offer advantages such as uniform load distribution and high performance[1].

Low Headroom Cranes

• Designed for spaces with limited headroom, these cranes have a compact size and low building headroom requirements. They are ideal for areas where traditional cranes cannot be used due to height constraints[1].

Explosion Proof and Special Application Cranes

• These cranes are designed for specific applications such as explosive environments or for handling special loads like grabs or magnets. They are customized to meet the unique needs of various industries[2].

Installation and Maintenance

Installation

• Overhead cranes require careful installation to ensure they are securely mounted and aligned properly. This may involve integrating the crane with the building’s structural elements or using freestanding systems[4].

Maintenance

• Regular maintenance is crucial to ensure the longevity and safety of overhead cranes. This includes checking the hoist/trolley, bridge beam, and runway systems for any signs of wear or damage[4].

Work Environment Considerations

Temperature

• Overhead cranes can operate in a variety of temperature conditions, typically ranging from -20 to +40 degrees Celsius. Some specialized cranes, like those used in casting environments, can operate up to +60 degrees Celsius[2].

Customization

• Overhead cranes can be customized to meet specific user requirements, including adjustments in lifting capacity, span, and lifting height. Customization ensures the crane fits the particular needs of the workspace[1][2].

Conclusion

Overhead cranes are versatile and essential tools in industrial settings, offering a range of capacities, spans, and lifting heights to suit various applications. Understanding the different types, components, and mounting options of overhead cranes is crucial for selecting the right equipment to enhance efficiency and safety in the workplace.
