Tadano 120 Ton Crane Load Chart: What a Fleet Buyer Checks Before Sourcing City Cranes and Wholesale Packages

Short version: if you are sourcing a Tadano 120-ton crane, ask for the load chart first. Ask before the price, before the delivery date, and before you get attached to a paint job. I will not authorize a purchase order for any crane until I have read the load chart for the exact configuration we intend to run. That habit has saved our fleet budget roughly $180,000 over the past six years because it caught three cases where a '120-ton' machine could not do the lifts our customers needed.

I'm a procurement manager at a 140-person equipment rental company. I've managed our fleet purchasing budget—about $4.2 million annually—for eight years, negotiated with 60+ vendors, and documented every order in our cost tracking system. I don't sell cranes and I don't get paid by any manufacturer. I am the annoying person who asks for documents nobody else requests.

The conventional wisdom is that in crane buying, the brand is the main decision. My experience with 60-plus vendors suggests otherwise—at least for 120-ton-class all-terrain cranes. The brand gets you to the short list. The configuration and the load chart make the final decision.

I don't have hard data on every 120-ton-class chart in the market. What I can say from the 14 charts I have reviewed in the past three years is that 3 out of 14 had a mismatch between the quoted configuration and the actual chart. That is not a rarity. That is a reason to verify.

What 120 Tons Actually Means

A Tadano crane with '120' in the model name does not lift 120 tons at every radius. It lifts 120 tons at a short radius, with the right counterweight, outrigger setup, boom length, and ground condition. Move the load out to the end of the chart, and capacity can drop dramatically. I am not going to give you a single load number here because there isn't one.

Why does the load chart matter more than the brand? Because a crane's capacity is an engineering calculation, not a marketing claim. According to ASME B30.5 (asme.org), the rated load is the maximum load for a specific set of conditions. In the U.S., OSHA (osha.gov) requires the operator to have access to the load chart. This is not a sales document. It is a compliance document.

What I Check on a Tadano 120 Ton Crane Load Chart

• Boom length and jib configuration for the lifts I actually have
• Counterweight options and whether they require extra transport
• Outrigger spread at full extension and at the intermediate position
• Serial number and revision date on the chart

The model number alone is not enough. A modern all-terrain crane load chart can run ten pages or more: main boom, fly jib, counterweight variations, rubber versus outriggers, even tire pressure. If a dealer sends me a one-page chart with no serial number, I ask for the full package.

One 120-ton quote in Q3 2024 had a 4% gap between the base price and the delivered price once freight, rigging, and the first service kit were added. The base number looked good. The real number was not on the first page. Actually, that is the kind of hidden cost that makes procurement managers insist on itemized quotes.

Crane Wholesale: Where the Savings Are

Now for the word everyone wants to hear: wholesale. Wholesale in cranes is not a straight discount. It is a commitment to buy a defined package. I learned that the hard way in 2022 when we bought a three-crane package. The headline price per unit looked great. But the cranes were not identical: different boom lengths, different counterweight configurations, and one had an older control system. Our cost tracking system later showed an extra $47,000 for parts and training to standardize them. A lesson learned the hard way.

What I should have asked for: one specification, three units, a common spare parts kit, and two days of operator training in the price. That sounds obvious. But in a three-unit quote, it is kinda easy to miss.

Wholesale price should be a line item in a total cost of ownership model, not a standalone victory. Whether you buy one crane or five, the verification steps are the same. The load chart, the serial number, and the after-sales support structure should be in the same email as the payment terms.

This matters even more if you are buying one crane. A supplier that treats a single crane inquiry like a nuisance is telling you something. When I was starting out, the dealers who took our first small orders seriously are the ones I still call for larger purchases. Small does not mean unimportant—it means potential.

City Crane Sourcing: What to Prioritize

City crane sourcing is a different problem. A city crane is a compact machine designed for jobs where a full-size all-terrain is too long or too heavy for the street. The marketing number says 'tons.' The actual decision often comes down to the width of the outrigger stance and the turning radius.

When I compared a city crane and a full-size all-terrain side by side for the same urban job, I finally understood why footprint beats peak capacity in a crowded jobsite. The all-terrain could lift more. It could not set up where the work was. The city crane got through the gate and set up with the outriggers partially extended.

Ask for the load chart with the outriggers in the intermediate position. Ask how long it takes to go from travel mode to lifting mode. Ask about counterweight travel. The intermediate outrigger position means less capacity. Not ideal, but workable if the chart says so and the site engineer signs off.

What a Tower Crane Specification Guide Can Teach You

If your project actually needs a tower crane, stop here and find a tower crane specification guide. Tower cranes and mobile cranes are different machines. But a good tower crane specification guide teaches one thing that carries over: a spec sheet is a set of constraints, not a single capacity number.

For a tower crane, the constraints include hook height, working radius, foundation load, and power supply. For a Tadano mobile crane, the constraints include boom length, counterweight, outrigger position, and ground bearing pressure. I do not have enough tower crane experience to offer a safely detailed guide. What I can tell you is that a specification guide is not a pricing sheet. It is a compatibility check.

Boundaries and Confessions

This advice has limits. First, a load chart is necessary but not sufficient. You still need a qualified operator, a site engineer, and a crane that has been properly inspected and maintained.

Second, the load chart must match the actual crane. I once assumed a used crane's chart would match the original brochure. Didn't verify. Turned out the previous owner had shortened the boom, so a machine quoted as a 120-ton unit was really doing the work of a 90-ton unit. The chart on file did not match the chart on the machine. Now I check the serial number on the chart against the serial number on the crane.

Third, prices change. I am not giving you a price list. The 4% gap quote I mentioned was from a Q3 2024 dealer quote, and the numbers moved before we signed. Verify current pricing at the date you are buying.

If you buy a tower crane, use a tower crane specification guide. If you buy a mobile crane, use the load chart. And get the load chart before the price. The price tells you what the machine costs. The load chart tells you what it can do. One of those numbers matters a lot more.
