Tadano Crane Buying: Load Charts, Private Label Risks, and Used Crane Compliance

If you are buying a Tadano crane under a deadline, the smartest thing you can do is ignore the paint and ask to see the load chart. In my role coordinating crane purchases for contractors and rental fleets, I’ve handled more than 200 rush orders over the last nine years—including same-day callouts when a project was about to trigger penalty clauses. The machines that caused my worst headaches were rarely the ones with mechanical problems. They were the ones with missing documents.

So here is the conclusion: a Tadano crane is only as useful as the compliance paperwork that comes with it. That rule applies to new cranes, used cranes, mobile crane private label deals, and overhead crane OEM purchases. If the original manufacturer can’t be connected to the load chart and inspection records, you aren’t buying a crane. You’re buying a future delay.

I don’t write about this from a sales desk. I’m the person who gets called when the first crane failed and a second one has to be found before the road closure expires.

What a Tadano 75 ton crane load chart actually tells you

The phrase “I need a Tadano 75 ton crane” doesn’t tell a lift planner enough. A 75 ton load chart is only valid under specific conditions: radius from the crane’s center of rotation, boom length, counterweight, outrigger position, and in some cases, the jib configuration. At a very short radius, a 75 ton crane may be rated to lift 75 tons. At the radius your job actually needs, the number may be far smaller.

In March 2024, a contractor called at 10 a.m. with a permit expiring in 36 hours. They asked for a “75 ton Tadano.” The machine we found could handle the job, but only because the lift planner checked the exact radius and the load chart that matched the crane’s serial number. The capacity class alone never would have flagged the problem.

The best question to ask when you see a used or rebuilt machine is simple: “Does this load chart have this crane’s serial number on it?” If the seller shows you a generic brochure from the internet, that is not a load chart. That is a hint.

Mobile crane private label: the real question is the OEM trail

A mobile crane private label arrangement is not automatically a red flag. A manufacturer builds a crane; another company rebadges and sells it. If the seller can prove which OEM built it and provide the original load chart and design documentation, you may get a good machine at a better value.

The trouble starts when the brand on the boom doesn’t match the original manufacturer’s records. “This is basically the same as that OEM model” is a phrase I don’t accept. “Basically” is not an engineering document.

I saw this happen on a private-label crane priced about $75,000 below comparable units. The seller was honest and said the load chart was identical to the OEM model. He just didn’t have the file. The lift planner would not certify the crane, and it took eleven weeks to get an engineer-signed chart. All of the price advantage disappeared in backup rental costs.

So when someone mentions a mobile crane private label, don’t panic. Do ask for the original OEM name, the serial number, and a chart that can be traced back to that OEM.

Overhead crane OEM: same rule, different building

If your project also involves an overhead crane, the same discipline applies. An overhead crane OEM is responsible for the structural design, rated load, duty classification, and documentation that tells your maintenance team how the crane should be used.

A local rep can paint a bridge, change the hoist, and put a higher capacity sticker on the beam. That doesn’t change the original OEM’s calculations. Ask the overhead crane OEM for original drawings, rated load documentation, and duty class information before you approve the design. In North America, that is often tied to CMAA specifications; in other regions, FEM classifications are common. Either way, the documentation should come from the manufacturer that did the engineering.

Used crane compliance requirements: the checklist I won’t skip

Used cranes are where procurement shortcuts show up. I treat used crane compliance requirements as part of the purchase decision, not as paperwork to handle after delivery. Here is the checklist I run through before I commit:

• Load chart and operator manual matching the serial number. For mobile cranes, ASME B30.5 treats the manufacturer’s load chart as the basis for safe operation. If the chart doesn’t match the machine, the capacity is unproven.
• Inspection and maintenance records. For construction cranes, OSHA’s regulations under 29 CFR 1926 Subpart CC include inspection and documentation duties. If the file is missing, count on spending time and money to get the crane inspected before it can work.
• Import, title, and emissions paperwork. A used crane moved across a border can have customs, registration, and engine emissions requirements. Ask for the title and any export certificates before you get emotionally attached.
• Certified modification records. If the crane has been reboomed, repowered, or structurally repaired, those changes need engineering approval. Without it, the original load chart may no longer be valid.
• Load test documentation. If a load test certificate exists, ask for it. If not, check whether your insurer, rental contract, or local jurisdiction requires one before the crane enters service.

This is general guidance, not legal advice. Used crane compliance requirements change by jurisdiction and machine configuration, so verify current requirements with someone qualified for your specific situation.

Why I’ll happily pay more for a complete paper trail

I am not saying you should ignore price. I am saying that the total cost of a crane includes the cost of waiting. A crane with missing load charts can sit at a job site while the crew is still getting paid. The replacement rental, the rescheduled lift, and the missed deadline can wipe out any purchase price advantage.

When I compared two similar 75-ton class machines side by side—one with complete documentation and a higher asking price, one cheaper with a thin file—I understood why value is not the same as price. The more expensive crane could be dispatched the next morning. The cheaper one was a guess. Buy the guess only if you can afford the downtime.

The exception: when I’m okay moving faster

There is one situation where I move quickly without turning over every page: when the seller is a dealer I’ve used for years, the machine history is known, and the documentation will be written into the purchase agreement before payment is released. Trust reduces checking time. It does not remove the need for a load chart and compliance records.

Get the documents before the truck arrives, not after. The deadline you can still meet is the one before you sign.
