I run logistics for a heavy equipment rental dealer. In my last three years, I've processed over 200 rental and sales orders for cranes — everything from a 30-ton Tadano to a 600-ton Demag. And here's the thing I've started telling clients straight up: don't buy a Tadano 30-ton crane just because you think you need a 30-ton crane.
That sounds counterintuitive for someone who sells these things, right? But after cleaning up after three separate purchase mistakes last year alone, I'm convinced that the 30-ton segment is one of the most misunderstood in mobile cranes. The problem isn't the machine. It's how people spec it.
The 30-Ton Trap
Most clients call me up and say, 'I need a Tadano 30-ton crane.' I ask, 'What's the heaviest lift?' They say, 'About 12 tons.' Then I ask, 'How far out?' And that's where it gets interesting.
A Tadano 30-ton all-terrain crane (like the GR-300EX or ATF 30G) can lift 12 tons — sure — but at what radius? At 10 feet, no problem. At 30 feet, you're already down to about 5 tons, depending on the configuration. And if you're using a jib? Forget it.
I had a client in July 2024 who insisted on a 30-ton Tadano for a bridge repair job. The heaviest component was 9 tons. The lift radius was 40 feet. The Tadano 30-ton's chart showed maximum capacity at that radius was 3.8 tons. They didn't believe me until I pulled up the Tadano 100-ton mobile crane load chart PDF — which showed that a 100-ton crane could handle that same lift at that radius with margin. They ended up renting a 100-ton for two days instead of buying a 30-ton that would have been dangerous.
Looking back, I should have caught that earlier. But the client had already fixated on the 30-ton number because their competitor had one. (Note to self: always verify radius before recommending a crane.)
Gantry Cranes vs. Mobile Cranes — A Different Conversation
Here's another thing that surprises people. When a client asks about a 30-ton Tadano for indoor or fixed-location work, I often steer them toward a gantry crane instead.
A gantry crane can lift the same load for a fraction of the cost — we're talking $15,000–$40,000 for a decent gantry system versus $200,000+ for a used 30-ton Tadano. But if you've ever had a gantry crane fail, you know that sinking feeling. I've seen a gantry collapse because the support legs weren't level, and the load shifted. The damage was $28,000 in repairs and a three-week delay. The client's alternative was a mobile crane — which would have cost more upfront but eliminated that risk.
So here's my rule: if your lift is predictable, repetitive, and within 10 feet of travel, get a gantry crane. If you need to move the crane around a jobsite or the radius varies, get a mobile crane. And if you need both, you rent, you don't buy.
What the Load Chart PDF Actually Tells You
The most frustrating part of this whole conversation: clients who buy a crane but never read the load chart. You'd think a $200,000 purchase would come with some homework, but I've seen professionals pull up a Tadano 100-ton mobile crane load chart PDF and skip straight to the max capacity number. They see '100 tons' and assume that covers everything.
Here's what that PDF actually shows you, if you bother to read it (and I recommend you do):
- Capacity at maximum radius — At 50 feet, a 100-ton crane might only lift 25 tons. At 100 feet, maybe 8 tons.
- Stability limits — That 100-ton rating assumes ideal ground conditions and no wind. On soft ground or in 20 mph wind, you need to derate by 20–30%.
- Jib configurations — If you're using a jib, the capacity drops drastically. Some charts show separate sections for jib not used vs. jib at specific angles.
- Outrigger spread — Full outriggers give you full capacity. Partial outriggers can halve it. No outriggers? You're at 10–15% of chart value.
A client in March 2024 tried to lift a 14-ton transformer using a 30-ton Tadano with partially extended outriggers. The load chart said the capacity at that radius with 50% outriggers was 6.2 tons. They didn't check. The crane tipped — not fully, but enough to cause $12,000 in damage and a fine from the safety inspector. They called me at 8 PM that night, frantic. I couldn't help them. They should have called me before the lift.
When to Buy Bigger (or Smaller)
So here's my honest recommendation — and this is where I might lose a sale, but I'm fine with that. If 80% of your lifts are within 15 feet of radius, and you're under 15 tons, buy a 30-ton Tadano. It's nimble, reliable, and parts are plentiful. But if any of your lifts are over 30 feet radius or 10 tons weight, you should be looking at the 100-ton class, or at least a 50-ton.
Why? Because the difference in purchase price between a used 30-ton ($150k–$250k) and a used 100-ton ($300k–$600k) is less than the cost of a single accident. And the 100-ton gives you way more flexibility for those occasional big lifts. The 30-ton is a scalpel. The 100-ton is a sledgehammer. Rent the scalpel; own the sledgehammer.
But then again, maybe you don't need a mobile crane at all. If you're working in a fixed location with planned lifts, I'd seriously consider a gantry system or even an overhead crane. You know your operation better than I do. But at least ask yourself: 'Do I need to move the lift point, or do I need to move the crane?' If it's the latter, buy mobile. If it's the former, buy stationary.
The Skeptic's Objection
Now, someone's going to read this and say, 'Sounds like you're just trying to upsell people to a bigger crane.' Fair point. Here's my response: I've turned away sales. I had a client in 2023 who wanted a 100-ton Tadano for a job that needed four lifts over two months. I told them to rent a 30-ton for two days for each lift, at $800/day, instead of buying a $400,000 crane that would sit idle for 90% of the year. They saved $380,000 and got the job done.
Bottom line: don't buy a Tadano 30-ton crane because you like the number 30. Buy it because it matches your specific lift radius, weight, and frequency. And if you're not sure, call someone who's cleaned up the mess when people bought the wrong crane. That's me. And I'll tell you the truth, even if it costs me a commission.
