What Size Crane Do I Need?
If you’re planning a construction or lifting project, one of the first questions you might ask is: "What size crane do I need?" Choosing the right crane size is super important to keep your job safe, efficient, and within budget.
In this guide, we’ll break down everything you need to know to pick the right crane size for your project. Whether you're lifting a hot tub over a house, erecting steel beams, or managing a big commercial build, we’ve got you covered.
Why Crane Size Matters
Using the wrong crane can lead to delays, higher costs, and even safety risks. If the crane is too small, it might not lift your load. If it’s too big, you could waste money and space. Picking the right size crane means safer lifts, smoother planning, and better value for your money.
Factors That Affect What Size Crane You Need
There’s no one-size-fits-all when it comes to cranes. Here's what you need to consider:
Weight of the Load
You need to know the total weight of what you're lifting. That includes the main object and any rigging gear like chains or spreader bars. Even small extras can add up, so be precise!
Lift Height
How high does the crane need to lift the load? Whether you're going over a building or placing materials on a rooftop, lift height will affect the type and size of crane you need.
Horizontal Distance (Lift Radius)
This is the distance from the crane to where the load is going. The further out the crane has to reach, the more lifting capacity it will need.
Site Access and Terrain
Think about where the crane will sit. Is the ground flat and solid? Or will the crane be on soft soil or in a tight space? These conditions help determine what type of crane is best and any other equipment requirements, such as crane mats.
Type of Load
Is your load heavy, wide, or awkwardly shaped? Irregular or fragile loads may need special rigging or more lifting power.
Weather Conditions
Wind, rain, or ice can impact crane stability. If your job is outdoors, factor in weather conditions when selecting your crane.
Common Crane Sizes and What They're Used For

Ideal for small residential projects
25-Tonne Crane
Good for small to medium construction jobs
Often used for roofing, steel erection, or lifting containers
60-Tonne Crane
Versatile for larger construction sites
Strong enough for heavy lifting, but still mobile
100+ Tonne Cranes
Best for major infrastructure or high-rise work
Requires careful planning and setup
How to Calculate the Right Crane Size
Here’s a step-by-step approach you can follow:
-
Know the exact weight of the load.
Include the weight of the rigging gear.
-
From pickup to placement.
Include obstacles like walls, fences, and buildings.
The radius is the distance measured from the centre of the crane’s slew ring to the centre of gravity of the load at its furthest point from the crane.
-
Make sure there’s enough room for crane setup.
Consider if extra support (like mats) is needed.
-
These charts show how much a crane can lift at different distances and heights.
A crane expert can help interpret it.
-
Every lift is different. That’s why only a qualified Lifting Appointed Person should choose the appropriate crane and rigging equipment for the job.

FAQs About Crane Sizes
Can a crane lift over a house?
Yes! As long as the crane has the right reach and lifting power, it can lift over buildings. Always measure accurately and check for overhead wires.
What’s the smallest crane available?
Mini cranes or spider cranes are great for small, indoor, or restricted access areas. They can lift surprising amounts despite their size.
Do I need to provide any measurements before hiring a crane?
Yes. The more details you provide (load weight, height, distance, site access), the more accurate the crane recommendation will be.
