Types of Overhead Cranes
Understanding the different types of overhead cranes is crucial for selecting the right one for your business. Below is a comparison table that outlines the main types of overhead cranes, their uses, and key characteristics.
| Crane Type | Description | Common Uses | Cost Range |
|---|---|---|---|
| Gantry Crane | A crane that uses a movable framework to support the hoist and trolley. | Shipping yards, construction sites, garages. | $4,000 – $40 million |
| Jib Crane | A crane with a horizontal arm that can rotate to lift materials. | Assembly lines, factories, and workshops. | $3,000 – $10,000 |
| Bridge Crane | A crane that runs on overhead runways and is typically used indoors. | Manufacturing plants, warehouses, and mills. | $10,000 – $100,000+ |
| Monorail Crane | A crane that runs along a single track and is often used for specific tasks. | Assembly lines, production facilities. | $5,000 – $50,000 |
Gantry Cranes
Gantry cranes are versatile and can be used in various settings, from shipping yards to small garages. They are built on a movable framework that supports the hoist and trolley. Gantry cranes come in different sizes, making them suitable for both heavy-duty and light-duty applications. Their mobility allows for easy relocation, making them ideal for tasks that require flexibility.
Jib Cranes
Jib cranes are characterized by their horizontal arm, which can rotate to lift materials over short distances. They are typically mounted on a wall or a dedicated support structure. Jib cranes are commonly used in assembly lines and factories due to their efficiency in lifting and moving materials within a limited radius. They are cost-effective and provide excellent reliability for short-distance lifting needs.
Bridge Cranes
Bridge cranes are the most common type of overhead crane, typically found in manufacturing plants and warehouses. They consist of two overhead runways built into the building’s support structure, with a bridge that moves along these runways. Bridge cranes can be configured as single girder or double girder, with double girder cranes offering higher lifting capacities and more hook height. They are ideal for moving heavy loads within a facility.
Monorail Cranes
Monorail cranes are unique in that they run along a single track, allowing for efficient movement of materials in a straight line. They are often used in production and assembly lines where space is limited. Monorail cranes can be designed to follow curves, making them adaptable to various layouts. Their simplicity and cost-effectiveness make them a popular choice for many manufacturing applications.
Conclusion
In conclusion, understanding the different types of overhead cranes and their technical features is essential for optimizing material handling in your business. Whether you need a gantry crane for mobility, a jib crane for short-distance lifting, a bridge crane for heavy loads, or a monorail crane for efficient movement, there is a solution that fits your needs. Companies like PWI Works, Mazzella Companies, Konecranes, and American Crane offer a range of options to help you choose the right crane for your specific requirements.
