Used Crane Distributor Buying Guide: Tadano 90t Cranes, Bulk Overhead Cranes, and Hoist Specifications

There Is No Single Right Way to Buy a Used Crane

I'm a senior equipment procurement coordinator at a crane distributor. In my role, I've handled 60+ rush orders in 9 years, including a same-day turnaround for a steel mill that was losing $30,000 an hour. So this is not a normal "used crane distributor buying guide" written from a glossy brochure. It's the way I actually think about a purchase when the cost of being wrong is measured in downtime, contracts, and safety.

Here's the thing: there's no universal answer. A used Tadano crane might be a great buy for one contractor and a terrible buy for another. A bulk overhead crane order can look perfect in a spreadsheet and fail in a real factory. The difference is which of three scenarios you're in. Let's identify yours before you ask one distributor for a quote.

The Three Buying Scenarios

• Scenario A: You need a specific Tadano crane model. This is where the spec sheet says "Tadano or equivalent" and the load chart already assumes a machine like a Tadano 90t crane.
• Scenario B: You're buying a bulk overhead crane package. Multiple units for a plant, not just one little hoist. Hoist specifications and duty class matter more than the unit price.
• Scenario C: You need a part or hoist replacement now. Production is stopped or a deadline is hanging over your head. Speed matters, but wrong speed matters more.

If you're not sure which one you're in, keep reading. The last section gives you a quick way to decide.

Scenario A: When You Need a Specific Tadano Crane

If you've ever been handed a load chart that didn't match the serial number, you know the sinking feeling. That's why my first question when someone says they need a Tadano 90t crane is never "what's the price?" It's "where is the load chart for this exact crane?"

Under ASME B30.5, a mobile crane's load chart and operation manual are supposed to remain with the crane. If a distributor can't show you the chart for the exact serial number, assume the crane has been modified, had its counterweight changed, or lost its paperwork. Any of those can turn a "90-ton crane" into a liability.

Counterintuitive advice: a high-hour Tadano crane that spent its life in a rental fleet can be a better buy than a low-hour privately-owned crane. Rental fleets have inspection schedules, oil sample records, and repair logs because their business depends on it. A private crane with low hours might have sat in a yard for years, or been run by one operator who never looked at the maintenance dashboard. When I compared two identical models side by side—one from a rental auction, one from a distributor with full service records—the cheaper rental auction crane cost me $38,000 in repairs before it ever worked a full week. The distributor option, with a $2,800 third-party inspection report and a serial-number-matched load chart, turned out cheaper even though the sticker price was higher.

What to ask for in this scenario:

• Original load chart for the exact serial number.
• Service history from the last 48 months, including any boom or cylinder repairs.
• Third-party inspection report from the last six months.
• Written list of what's NOT included in the price: freight, rigging, load test, export documents, commissioning.

That last question matters more than you think. The distributor who puts every fee in the quote—even if the total looks higher—is the one who usually costs less at the end. I've learned to ask "what's not included" before I ask "what's the price."

Scenario B: Buying a Bulk Overhead Crane Package

When I say "bulk overhead crane," I mean an order for multiple cranes in one purchase—maybe a new fabrication shop, maybe a production line with several bays. This is a completely different animal from buying one mobile crane.

The trap is comparing quotes by price per crane. A 10-ton overhead crane is not a fixed product. It's a combination of hoist specifications, bridge design, duty class, runway, controls, and installation. Two quotes for "10-ton overhead cranes" can differ by 20% and the cheaper one can be the wrong machine.

Start with the hoist specifications. I don't mean "capacity and lift height." I mean:
- rated capacity and class of hoist
- lifting speed and motor horsepower
- voltage, phase, and control voltage
- duty class under CMAA Specification 70 (Class A through F)
- headroom and hook path
- trolley travel and bridge speed
- mounting dimensions and existing runway constraints

Why duty class? A Class C crane is fine for light assembly. If you're running 20 full-load lifts per hour, you need Class D or heavier. It's a bigger upfront number, but it's the difference between a hoist that lasts and a hoist that burns up during the busiest season. The most expensive overhead crane is the one that's down.

I also made the cheap mistake once. I saved $4,000 by skipping a third-party load test on a used overhead crane. End result: $17,000 in hoist repairs and a shutdown that cost a week of production. Net loss: $13,000 plus trust from the plant manager. Don't do that.

For a bulk purchase, ask for a common spare parts list. If you standardize on one brand and one hoist configuration, you only need to stock one set of brakes, contactors, and limit switches. That's a hidden cost that never appears in the initial quote.

The distributor who lists all fees upfront—even if the total looks higher—usually costs less in the end.

And don't let anyone skip the marking and inspection requirements. OSHA 29 CFR 1910.179 requires the rated load to be marked on each overhead crane, and load testing is part of the acceptance process. If a distributor treats a load test as an optional upsell, that's your signal to keep looking.

Scenario C: When You Need a Hoist or Part Yesterday

In March 2024, a client called at 4:15 PM. Their overhead crane was down, and the factory was losing $12,000 per hour of downtime. The original hoist was dead, and they needed a replacement by the next morning. The normal lead time from the OEM was six weeks. Their supplier said "no chance."

That was a real rush order, and it taught me the difference between "fast" and "right." The fastest fix isn't always the closest supplier. It's the supplier who asks more questions before giving an answer.

I said "I need a 10-ton hoist." They heard "same dimensions and electrics as the last one we sold you." We discovered the mismatch when the replacement arrived: the hook path was two feet shorter and the control voltage didn't match. That mistake cost more than the part.

Now the first thing I do is photograph the nameplate. The exact hoist specifications matter: capacity, model number, rated lifting speed, motor duty, voltage, phase, hook approach, mounting style. If a distributor asks for the nameplate and the serial number, they understand how cranes work. If they say "it's the same thing" without seeing it, run.

This applies to Tadano cranes too. For a Tadano crane part, "compatible" is not a spec. You need the actual rating and a drawing or part number that matches your crane's serial number range. Aftermarket parts can be fine, but only if someone verifies the engineering, not just the price.

And in an emergency, be honest about your deadline. "As soon as possible" means different things to different people. I've learned to say "I need it on site by Friday, and here's what I'll pay for freight." That gets a real answer. A vague "rush it" gets a vague response.

Use This Quick Test to Know Which Scenario Applies

Ask one question: what are you really buying?

• If you're buying a specific lifting solution for a known load, you're in Scenario A. Verify the load chart and the crane's exact configuration before you worry about price.
• If you're buying many cranes or cranes for a facility that has to run all day, you're in Scenario B. Compare duty class, hoist specifications, and spare parts commonality first.
• If you're buying time because something is already broken, you're in Scenario C. Get the nameplate, get the exact specs, and get the deadline in writing.

Most buyers are not in one scenario. Maybe you're buying a used Tadano 90t crane for a rental fleet—that's Scenario A plus B. Maybe you're buying one hoist to replace a failed unit and hoping to standardize the rest of the plant later—that's Scenario C plus B. When in doubt, apply the stricter test. The cost of being wrong is not the purchase price; it's what happens after the crane is installed.

Bottom Line: Buy the Crane You Can Prove

If you take one thing from this used crane distributor buying guide, take this: the goal isn't to find the cheapest crane. It's to find the crane whose history, specifications, and total cost you can actually verify. The supplier who shows you numbers without hiding the fees is the supplier who will be there after the sale.

I've made expensive mistakes. I've also made good calls. The difference is almost never the brand price. It's how much I knew before I committed. Know your scenario, know your hoist specifications, know your load chart, and ask the uncomfortable question: what's not included?

That question has saved me more money than any discount ever did.
