How to Build a Crane

How to Build a Crane

Forecasts show that the global crane and hoist market could reach $4.87 billion by 2028.

Building a crane is not the most complicated process, but it is essential that there are no mistakes. Any oversights in the construction of a crane could result in it collapsing, causing huge amounts of damage.

If you’re interested in the basics of how to build a crane, keep reading.

1. Establish the Location

Making sure the crane is in the most suitable spot is essential. It needs to be in an open space with plenty of room to move, and you should take wind patterns into consideration.

There are also strict placement rules that you must follow. For example, the crane cannot be within 10 feet of power lines.

2. Create the Foundation

Before the crane building can begin a strong foundation is needed to ensure the crane stays stable. The size of the foundation will vary depending on the dimensions of the crane. A rough general size would require a five-foot-deep hole and measure about 30 x 30 feet.

After laying the foundation you should give it a few days to settle before continuing. You’ll want to check the base regularly to be sure it hasn’t sunk at all or settled incorrectly.

If there are any issues the whole foundation may need to be redone. It’s better to make sure it is right from the start to avoid finding out later if the crane collapses.

3. Construct the Initial Tower

The first step of building a crane involves attaching the first mast to the base, usually with anchor bolts that stick out from the substructure. Once secure, you can stack more masts to reach the height needed for the first stage of construction.

Throughout this, and while the crane is in use, the base should be monitored to make sure the load isn’t too heavy and that the elevation is correct.

4. Construct the Slewing Assembly

The slewing assembly consists of a number of components that enable the crane to move in different directions:

• Horizontal jib
• Counter jib
• Cab
• Slewing ring
• Tower top

You can assemble this piece by piece, or if desired it can all be assembled as one part and then lifted onto the initial mast when ready.

5. Adjust the Height

A hydraulic jack along with the top climbing unit makes it possible to lift the slewing assembly while adding new masts. This allows you to increase the overall height of the crane whenever needed.

What to Do After You Build a Crane

Before the crane is used for construction you should carry out a complete inspection and load test. Observing structural elements throughout a load test and re-inspecting after will reveal any issues such as cracks or leaning. It is important to address these immediately.

A licensed technician must also carry out an inspection on any switches, cables, and brakes before use.

These tests may vary for different types of cranes.

Other Crane Building Tips

Cranes are varied, complicated machines, with a lot of different capabilities depending on the type of crane in question.
