Tadano Cranes: Load Charts, Used Units, and the Questions I Keep Getting

If you're here because you typed 'Tadano 30 ton crane load chart' into a search bar, I get it. You need a load number, not a sales pitch. I've been handling crane rental and purchase orders for nine years, and I've personally made (and documented) 17 significant mistakes, totaling roughly $50,000 in wasted budget. This post is the FAQ I wish I'd had before I started. It covers load charts, used Tadano cranes, and a few odd search terms that keep landing on this page.

Here are the questions I get asked the most:

• What exactly is on a Tadano 30 ton crane load chart?
• Does a 30-ton Tadano actually lift 30 tons?
• Buying used Tadano cranes: what should I check?
• What's the deal with Tadano and Demag?
• Can I use a Hess truck to move a Tadano crane?
• Do I need a Dewalt air compressor on a Tadano jobsite?
• Heron vs crane: is that a bird question?
• Which Tadano crane is the right one for me?
• What's the mistake nobody warns you about?

1. What exactly is on a Tadano 30 ton crane load chart?

A load chart is a table of rated capacities for one crane configuration. On a Tadano 30-ton rough-terrain crane (like the GR-300EX), the 30-ton figure only appears in a narrow window: outriggers fully extended, counterweight installed, boom at minimum length, and the load as close to the crane as the chart allows. Move the load out to 25 or 30 feet, and rated capacity can drop by more than half.

I learned this by paying for it. In 2019, I quoted a steel package using the top number on a 30-ton chart without subtracting hook block and rigging weight. The lift plan came back with barely 3% margin. We had to add a second lift, which meant $2,900 in extra mobilization and a three-day delay. The lesson: load charts are not marketing pages. Use the chart mounted inside the cab for the exact serial number of the crane.

According to OSHA's construction crane standard (29 CFR Part 1926, Subpart CC), the employer must keep operation within the load chart capacity. ASME B30.5 covers mobile crane safety. You don't need to become a standards expert, but you do need to treat the load chart like a legal document.

2. Does a 30-ton Tadano actually lift 30 tons?

Yes, but only in the right configuration. In real work, you're lifting at a radius, and radius reduces capacity. Exact numbers depend on the model, boom extension, and whether a jib is fitted. If someone tells you 'a 30-ton crane will lift 30 tons anywhere,' that person hasn't read the chart.

Honest advice: if a planned lift is running above 90% of rated capacity, get a bigger crane or rethink the method. Operating at the edge of a chart is not how you want a Friday to end.

3. Buying used Tadano cranes: what should I check?

If you're shopping for Tadano used cranes, start with the load chart. I've lost count of used-crane deals that fell apart over missing or mismatched load charts. One seller told me the load chart was the same as a newer model. It wasn't. The counterweight and boom nose were different, so the capacity was different.

Before you commit to a used Tadano crane, work through this checklist:

• Request the load chart with the serial number. If it doesn't match the machine, don't buy it.
• Confirm the machine is in the Tadano parts portal, especially for Demag-branded units after the 2019 acquisition.
• Inspect winch, slew ring, cylinder seals, and tires. Don't trust the hour meter alone.
• Test the load moment limiter and anti-two-block system before payment.
• If the crane was imported from another market, check certification and safety labeling for your local rules.

On one 30-ton unit I went back and forth for two weeks. The used price was 30% lower than a factory-certified unit, and the crane had decent hours. But the load chart didn't match the exact configuration, and the seller couldn't explain why. I walked away. That decision saved more than the price difference.

Used Tadano cranes are a smart choice for a contractor who knows the lift profile and can handle maintenance in-house. But if you want plug-and-play with no surprises, consider a factory-certified used unit. Honest limitation: I can't tell you which route is cheaper for your tax situation. That depends on your own numbers.

4. What's the deal with Tadano and Demag?

Tadano acquired Demag's mobile crane division in 2019. People still ask if that makes every Demag crane a Tadano. No. Demag models keep their own load charts, and older machines have their own parts quirks. What has changed is the support network. In my experience, parts availability has improved after the acquisition, not gone backward.

I'm not a Demag integration specialist, so I won't pretend to know every part number. What I can tell you from an ordering perspective: always check the serial number in the current Tadano parts portal before you buy a used unit. If it's not there, call a dealer first.

5. Can I use a Hess truck to move a Tadano crane?

This question shows up because people search 'hess truck' and end up on a crane blog. Maybe you're thinking about a heavy-haul truck, or maybe about the toy trucks with the same name. Either way, no. You don't move a 30-ton Tadano on a regular truck. You use a lowbed or drop-deck trailer rated for the axle loads, or you drive the crane itself if it's a roadable all-terrain.

The hard part isn't finding a big truck. It's permits, route surveys, bridge ratings, and escort requirements. I'm not a transportation engineer, so for exact numbers, talk to a heavy-haul carrier. What I've learned from watching bad moves: never let a broker call it 'just a big flatbed.'

6. Do I need a Dewalt air compressor on a Tadano jobsite?

Another odd search term that lands on crane pages. A portable Dewalt air compressor—or any small jobsite compressor—is useful for inflating tires, dusting out control cabinets, running small pneumatic tools, and testing air horns. I keep one in the service truck.

But don't connect an external compressor to the crane's brake reservoir. An external unit can over-pressurize the system and damage valves. I watched a rental return turn into a brake valve rebuild because someone tried to 'help' with an air chuck. Read the crane's service manual first.

7. Heron vs crane: is that a bird question?

Yes. And I'm not an ornithologist, so I'll stay in my lane. Herons and cranes are different bird families. In flight, herons tuck their necks into an S-shape; cranes keep their necks straight. The construction crane got its name because the machine's boom resembles the bird's neck.

If you typed 'heron vs crane' looking for a bird ID, now you know. If you typed it looking for a lifting crane, the 'neck' is called a boom, and the load chart tells you what it can carry. No bird identification is required.

8. Which Tadano crane is the right one for me?

There's no single best Tadano. There's the one that fits your lift profile. Tadano's lineup covers rough-terrain, all-terrain, crawler cranes, and boom lifts, roughly from 20 tons up to over 600 tons.

• Firm ground, tight sites, indoor work: a rough-terrain crane like the 30-ton GR series.
• Road travel between distant jobs: an all-terrain model makes more sense.
• Soft ground or heavy long-reach lifts: a crawler crane is worth the setup time.

For many contractors, a 30-ton Tadano is the practical middle ground. It's small enough to maneuver and big enough for most equipment moves. But if your regular lift is in the hundreds of tons, don't try to save money with a 30-ton machine. Rent the size that covers your lift plan with some margin.

9. What's the mistake nobody warns you about?

Site access and clearance. I once rented a 50-ton crane for an indoor job and didn't measure the ceiling height. The operator arrived, looked at the building, and said the boom needed four more feet to assemble. We paid standby, brought in a smaller crane, and lost a day.

The data sheet said the crane would fit. My gut said the building was tight. I trusted the data sheet. The data sheet wasn't on site. Now every booking starts with a site walk: gates, overhead lines, ceiling height, ground slope, and outrigger room. It basically comes down to access. If you can't get the crane to the lift, the load chart doesn't matter.

Bottom line: Tadano makes a broad range of mobile cranes, and the load chart is the only honest starting point. For a 30-ton crane, get the chart for the exact serial number. For used cranes, verify the documentation before you get excited. And if you got here looking for a Hess truck, an air compressor, or a bird with long legs, at least now you know what a load chart is. That's more than I knew in 2016.
