Spoiler: bigger isn’t always better — it’s about the right lift
Mobile cranes come in all shapes, sizes, and “OMG that’s massive” categories. But choosing the right crane isn’t just about flexing with the biggest one in the yard — it’s about getting the job done efficiently, safely, and affordably.
Let’s break it down so you can lift like a boss and rent smart
Why Crane Size Actually Matters
Too small? The crane can’t handle the weight or height = delays, danger, disaster.
Too big? You’re paying for power you don’t even need = wasted budget.
The perfect fit = max efficiency, lower cost, smoother lift.
3 Main Factors to Know Before Choosing
Here’s the holy trinity of crane sizing:
1. Load Weight
How heavy is the thing you’re lifting?
Always know the actual weight — not a guess
Factor in lifting accessories (slings, spreader bars, etc.)
If in doubt, round up, not down
Example: A 5-ton HVAC unit + rigging = don’t rent a crane rated for just 5 tons.
2. Lift Height (aka Hook Height)
How high does the crane need to go?
Include the distance from ground to the highest lift point
Consider roof edges, scaffolding, nearby buildings
Add a bit of clearance — trust us
Lifting to the 6th floor? That’s 60–80 feet — depending on structure.
3. Lift Radius (Boom Reach)
This is where things get spicy
The radius is the horizontal distance from the crane’s center to the load.
The farther the reach, the more power (and stability) the crane needs.
Closer = smaller crane
Farther = longer boom = bigger crane
Don’t forget: boom angle affects capacity!
Tip: Crane capacity drops significantly as radius increases. That’s just physics, baby.
Bonus Factor: Site Conditions
Where’s the crane going?
Rough terrain? You'll need an all-terrain or rough-terrain crane
Tight urban space? Compact or truck-mounted works best
Limited access? Telescopic boom FTW
Crane size isn’t just about the lift — it’s also about where it happens.
Example Setup:
Scenario: You need to lift a 4-ton generator to a rooftop 40 feet high, 20 feet away from the crane.
You’ll Need: A crane rated for ~5 tons at 20ft radius + 50–60ft boom length.
Recommended Type: Truck-mounted crane with telescopic boom.
Operator: 100% yes. Always.
