What to Look for in a City Crane Distributor: A Tadano Load Chart Checklist

I coordinate crane procurement for a regional equipment dealer. In 12 years, I've handled 200+ rush orders, including same-day turnarounds for infrastructure clients. This checklist is for anyone who needs a city crane distributor and wants to avoid the kind of mistake that triggers a penalty clause.

It's not a complete crane engineering guide. It's a practical, do-this-in-order list, the same one I use when vetting a used crane wholesale supplier or checking a Tadano crane quote.

Who This Checklist Is For

Use this when:

• You're renting or buying a mobile crane for a project with a hard start date.
• A dealer has offered you a used Tadano or similar unit and you need to verify the specs.
• You're comparing a local distributor against a yard 500 miles away.
• You received a load chart by email and need to know whether it actually covers your lift.

If you're in a hurry, skip the background. The six steps below are the ones that matter.

Step 1: Confirm the exact model and serial number before price

The worst mistake I see is negotiating price before anyone has confirmed the exact machine configuration. I made this myself in my first year. I asked for a "90-ton Tadano," and the dealer quoted me a 90-ton class machine with a different boom length than the job required. Cost me a redo—about $600 in extra rigging, plus the client's trust.

So step one is boring but critical: get the model number, serial number, and year in writing. Then ask for the official Tadano 90 ton crane load chart for that specific machine. Not a sample. Not a summary. The full chart, with the machine's configuration listed.

According to Tadano's published specs (tadano.com), capacity on any given boom length and radius depends on counterweight, outrigger position, and optional fly equipment. A load chart without those details is just a marketing slide.

Step 2: Check the load chart against your tightest picks

Don't just file the load chart. Look at the three or four picks on your lift plan with the least margin. If your job needs 22,000 lbs at a 50-foot radius with 80 feet of boom, find that cell on the chart. If the machine is rated at 21,500 lbs at that point, it's the wrong machine. If it's 23,500 lbs, you have 2,000 lbs of margin—workable, but still tight.

Deadline pressure always pushes people to skip this step. In March 2024, a client called at 5pm needing a 90-ton class crane for a pipeline job starting in 48 hours. Normal lead time was ten days. We found a used crane wholesale yard with a machine that "should work." I pulled the load chart before committing—good thing, because the boom configuration was two sections short. We found another distributor with the right machine, paid $1,800 in emergency freight and inspection fees (which, honestly, felt excessive at the time—or rather, $1,500 freight plus $300 inspection), and delivered on time. The client's alternative was a $50,000 penalty clause.

Was the $1,800 worth it? Yes. What you're really paying for in that scenario is certainty, not just speed.

Step 3: Ask about after-sale support

A crane that arrives on time but has no documentation or technical support is a liability. Ask these questions directly:

• Do you provide the operator manual, maintenance records, and inspection reports?
• If a warning light comes on, who answers the phone?
• Are parts in stock, or do we wait for a shipment from Japan?

The surprise wasn't the price difference between the dealer with full documentation and the one without. It was how much hidden cost came from the missing manual—diagnostic time, a backup rental, and a seven-hour phone tag to find the right schematic.

What to look for in a city crane distributor is not just inventory. It's the after-sale support that keeps the machine working when you're already behind schedule.

Step 4: Verify the delivery plan, not only the delivery date

Anyone can say "we'll deliver Tuesday." The better question is: how?

"Your crane is on the way" is not a delivery plan.

I once had a vendor say "as soon as possible." They heard "whenever convenient." Result: delivery came two weeks later than I expected, because the lowbed driver had three other stops before mine. We were using the same words but meaning different things. We only discovered this when we asked for a tracking number and the vendor couldn't provide one.

For a used crane wholesale order, the delivery checklist is:

• Who is the carrier, and do they have crane-specific lowbed experience?
• Can the distributor share the truck's live GPS location during transit?
• What happens if the breakdown occurs? Is there a backup carrier?
• Who pays for delays that aren't weather or force majeure?

In Q3 2024, we processed 47 rush orders with a 95% on-time rate. The 5% we missed all had one thing in common: a vague delivery promise with no backup plan.

Step 5: Confirm inspection and certification paperwork

This is the step people skip because it feels like a formality. It's not.

Ask for the last annual inspection report and any load test certificates. If the unit is coming from another state, verify the paperwork satisfies your state's requirements. Missing annual inspection can shut down a job faster than a broken hydraulic hose.

A good Tadano crane dealer will have this ready. A bad one will say "we'll send it later." I want to say that in my experience "later" never arrives before the lift—but don't quote me on that; actually, I'll quote myself: it never arrives.

Step 6: Build a buffer into the schedule

I've tested six different rush delivery options in the last three years. Here's what actually works: assume the first promised date is wrong, and create a buffer.

If the client says the crane is needed on Monday, aim for the distributor to deliver by Friday. That gives you two days to absorb the unexpected—a missing pin, a flat tire on the trailer, or a new operator who needs a familiarization ride.

This ties back to the core viewpoint: an uncertain cheap delivery is more expensive than a certain expensive delivery. You don't need the cheapest distributor. You need one who hits the date. The extra rush fee buys a committed driver, a committed lane, and a committed backup plan. That's worth real money when your own deadline is already tight.

Common Mistakes to Avoid

Assuming "standard" is standard

In this industry, "standard" varies by distributor, by region, and by machine. A "fully equipped" Tadano from one yard might be base spec from another. Define everything in the purchase order: boom length, fly, counterweight, block, and line parts. If it's not in writing, assume it's not included.

Using the load chart as a substitute for a site plan

The load chart tells you what the machine can do in a specific configuration, not where the wheels should be. A Tadano 90 ton crane load chart is a capacity table, not a lift plan. Ground conditions, outrigger placement, and rigging must still be checked by someone qualified.

Forgetting the tower crane question

If your project involves tower cranes, the same verification logic applies. What to look for in a tower crane supplier is not just "do they have a tower crane available?" It's: which model, what jib length, what capacity at the farthest working point, and what certification does the operator hold? Same discipline, different machine.

Final Note

This checklist won't make you a crane engineer. But it will help you ask the right questions before you commit to a city crane distributor or a used crane wholesale deal. In an emergency, the smallest thing—a missing load chart, a vague delivery date, an unverified serial number—is often what costs you the most.

And if you're ever in doubt, pay for certainty. The extra $1,800 in rush fees is painful for a week. The $50,000 penalty clause is painful for a lot longer.
