11 Types of Cranes Commonly Used in Construction
Cranes have a long history of being a staple in construction that reaches back thousands of years. Records indicate the ancient Greeks invented the first cranes and used them as early as 515 BC. Some reports indicate cranes were used for water irrigation in ancient Mesopotamia, thousands of years earlier. In fact, many ancient structures, if built today, would need to use some sort of crane.
It was during the Industrial Revolution that cranes became integral to the modernization of the world, replacing the manual pulley system with an engine and an operator that preceded them. Today, different types of cranes can be found on almost any construction project, each one specializing in its own specific task.
There is a downside to this variety, however: because there are so many cranes available, it can be challenging to know which one does what. Due to the specificity each crane provides, getting the wrong type can cause delays and budget issues. Understanding the differences between each crane can help you figure out which one to use on your project, so you can rent the right crane at the right price.
To help you choose the right machine, we’ve broken down the different types of cranes (mobile and fixed) and their uses below.
Types of Cranes
Mobile Cranes
Mobile cranes are mounted on crawlers or tires and offer greater mobility than standard cranes. Some mobile cranes are even able to be driven on the highway. Their ability to navigate around job sites and carry large amounts of weight makes mobile cranes a very popular addition to many projects.
| Crane Type | Key Features | Primary Applications |
|---|---|---|
| Carry Deck Crane | Small, four-wheeled, rotates 360 degrees | Confined spaces, easy setup |
| Crawler Crane | Track vehicles, adaptable on soft ground | Long-term projects, heavy lifting |
| Floating Crane | Used at sea, crane vessel or ship | Marine construction, ports, oil rigs |
| Rough Terrain Crane | Four large rubber tires, off-road capabilities | Off-road operations, rough terrains |
| Truck-mounted Crane | Carrier truck with boom, easy road travel | Road transport, bridge construction |
Fixed Cranes
Fixed cranes are typically fixed in one location or spot, and most need to be brought in and assembled at the site of the project. What fixed cranes lack in mobility, they make up for with the ability to lift heavier loads and reach even greater heights. These crane types are set in place for the duration of a project.
| Crane Type | Key Features | Primary Applications |
|---|---|---|
| Bridge/Overhead Crane | Resembles a bridge, hoist travels along beams | Industrial environments, heavy lifting |
| Gantry Crane | Supported by A-frame legs, built on a track | Shipping docks, cargo handling |
| Jib Crane | Mounted over a workstation, used for repetitive tasks | Factories, assembly lines |
| Bulk-handling Crane | Specialized hook for bulk materials | Coal, minerals, large volumes |
| Hammerhead Crane | Horizontal swiveling lever on a fixed tower | Construction projects, heavy lifting |
| Stacker Crane | Automated, forklift-like mechanism | Warehouse storage, cold environments |
| Telescopic Crane | Hydraulic cylinder for changing length | Versatile lifting, adaptable for various tasks |
| Tower Crane | Fixed structure, high lifting capabilities | Tall buildings, large construction projects |
Choosing the Right Crane
When selecting a crane, consider the project’s terrain, the size of the project site, the weather, and the weight of the materials. You also want to consider the length of the project, as some cranes, like the crawler crane, are better used for long-term projects than their counterparts. Once you have all of your project specs, you’ll be able to determine which type of crane you’ll need for a successful construction job.
Conclusion
Cranes are essential tools in the construction industry, providing the necessary support for lifting and moving heavy materials. Understanding the different types of cranes and their specific applications can help ensure that you choose the right equipment for your project. Whether you need a mobile crane for flexibility or a fixed crane for heavy lifting, knowing your options will lead to a more efficient and successful construction process.
FAQs
1. What is the primary function of a crane?
Cranes are used to lift and move heavy objects, making them essential in construction and industrial applications.
2. How do mobile cranes differ from fixed cranes?
Mobile cranes are designed for mobility and can be moved from site to site, while fixed cranes are stationary and typically used for heavy lifting in one location.
3. What type of crane is best for rough terrain?
Rough terrain cranes are specifically designed for off-road operations and can navigate uneven surfaces effectively.
4. Can cranes be used in marine environments?
Yes, floating cranes are specifically designed for marine construction projects, such as ports and oil rigs.
5. What safety measures should be taken when operating cranes?
Operators should be certified, conduct daily inspections, and ensure clear communication during lifting operations to prevent accidents.
