Tadano Crane Sourcing FAQ: 100t Mobile Cranes, Used Suppliers, and OEM vs Private Label

I coordinate emergency crane sourcing for a heavy civil contractor. I've handled 120+ rush equipment orders in 11 years, including same-day replacements for shutdown and bridge-panel clients. When I'm triaging a rush order, I care about three things: time left, feasibility, and the worst-case risk.

Below are the questions that come up most when buyers are trying to source a Tadano crane, vet a used crane supplier, or decide between mobile crane OEM vs private label options. Short answers, no fluff.

What should I know first about a Tadano 100t mobile crane?

A 100t class Tadano 100t mobile crane is not a single capacity. Usable capacity changes by radius, boom length, counterweight, outrigger spread, and configuration. A Tadano ATF 100G-4 in some markets might lift 100t at a short radius with full counterweight, but only a fraction at 40m radius. Under OSHA 29 CFR 1926.1417, you cannot exceed the manufacturer's load chart. So before you call any crane truck supplier, pull the exact load chart for the model and year. If your lift needs 28t at 32m radius, do not assume a 100t crane works. It may not. Also check transport permits, axle loads, and site access. In a rush, the most expensive crane is the one that cannot get to the pick point. Simple.

Under OSHA 29 CFR 1926.1417, a crane must not be loaded beyond the manufacturer's rated capacity. For mobile cranes, ASME B30.5 is the consensus safety standard. Verify current editions at osha.gov and asme.org.

OEM vs private label for mobile crane parts: what is the real difference?

For mobile crane OEM vs private label, the difference is not just the logo. OEM usually means the load chart, service documentation, and load-path components are controlled by the original crane manufacturer. Private label can be a rebranded crane or parts built by a third party. That can be fine for non-critical items like mirrors, cab fittings, and some hydraulic filters, if traceability and specs match. But for load-bearing components, brakes, slew rings, boom sections, and safety systems, I stick with OEM or OEM-approved. Why? Liability and resale. If something fails, you want a paper trail that matches the crane's serial number. I am not a crane engineer, so I cannot approve substitutions. What I can tell you from a sourcing perspective: get the manufacturer's written approval before any critical swap. No approval, no rush. That is the rule.

How do I vet a used crane supplier without wasting a week?

Start with three proof points: serial number, maintenance records, and a recent load test or inspection. A real used crane supplier will send a video walkaround the same day, show the hour meter and boom cycle, and let a third-party inspector visit. If they say the crane is in another yard or will not share the serial, that is a red flag. For a Tadano crane, verify the model plate, year, and load chart match the serial. Ask for the last annual inspection under OSHA and ASME B30.5. If they cannot produce it, price in a full inspection. Honestly, a cheap used crane without records is rarely cheap. In my first year, I made the classic spec error: I assumed 100t meant the same usable capacity at every radius. It does not. Cost us a re-rig and a day.

Where can I find a reliable crane truck supplier when the deadline is tight?

Define the machine first. A crane truck supplier may mean a truck-mounted crane, a boom truck, or a mobile crane on a carrier. If you need a Tadano 100t mobile crane, you are usually in all-terrain or rough-terrain territory, not a standard crane truck. Call three types of suppliers: authorized Tadano dealers, national rental fleets with late-model units, and specialized heavy-haul partners who broker cranes. Ask two questions: What is the exact model and year? Can you confirm the load chart for my radius? If they hesitate, move on. In March 2023, we had a 100t crane confirmed verbally for a bridge-panel job. The supplier sold it to another buyer. We lost 18 hours and paid $11,000 more for a replacement. That changed how I think about backup planning. Now I get written confirmation and a backup option before I release the lift plan.

Is a Tadano crane worth the premium for emergency work?

Usually, yes, if the job is deadline-critical and the lift is complex. Tadano's advantage is not just brand name. It is documented load charts, parts availability through dealers, and predictable service support. On a rush job, that predictability is worth a lot. But if you are lifting simple loads at short radius, a lower-cost crane may be fine. This is where honest limitation matters: a Tadano is not the best choice for every budget. If you need the cheapest possible 25t pick for a one-day job, you might be paying for capability you do not use. For 100t lifts with tight radii, long booms, or high duty cycles, the premium often pays back in uptime and resale. As of January 2025, used pricing and availability change weekly, so verify current rates and hours before you commit.

What specs actually matter on a Tadano 100t mobile crane?

Ignore the headline tonnage until you check these: load chart at your required radius, boom length, jib options, counterweight configuration, outrigger base, and axle load. Then add transport dimensions and permit requirements. For a Tadano 100t mobile crane, the difference between a 12m radius pick and a 36m radius pick is huge. Also check hook block, rope condition, and whether the crane has the correct anemometer and LMI calibration. If you are buying used, ask for the last calibration certificate. If you are renting, ask who pays for permits and escort vehicles. Bottom line: the load chart is the contract. Everything else is logistics.

What are signs a used Tadano crane is not right for your job?

Three signs. One: the seller cannot provide a load chart for the exact serial number. Two: maintenance records show repeated hydraulic or electrical repairs. Three: the crane has been sitting for more than a year without an inspection. Any of those means you are buying risk, not capacity. Also watch for grey-market imports with non-compatible controls or emissions packages. That can be a parts nightmare. I am not a crane engineer, so I cannot speak to structural fatigue. What I can tell you from a procurement perspective is to hire an inspector who knows Tadano. Pay for the inspection before you pay for the crane. A $1,500 inspection can save a $150,000 mistake.

What is the one thing buyers miss in a rush crane order?

They focus on the crane and forget the support system. The crane is only one part. You need the right operator, rigging, ground bearing, permits, and a delivery window that matches the site. In a rush, the bottleneck is often not the crane. It is the lift plan approval or the road permit. Start those in parallel. If you are comparing mobile crane OEM vs private label, also compare who will support you after the sale. A private-label crane might look cheaper, but if the load chart owner will not answer the phone at 6 a.m., you are on your own. That is the real test. Not price. Support.
