Let me start with what I do: I'm the procurement manager at a 65-person industrial construction company. I've managed our mobile crane budget for the last eight years, and in 2024 that budget was around $640,000 between rentals, maintenance, and one lease payment. I didn't grow up as an operator, so I evaluate cranes the same way I evaluate any capital purchase: what will it cost to own, run, and support over five years?
The questions below are the ones I hear from our estimators and from other contractors considering a Tadano crane. I'll answer them in the order they usually come up.
What is a crane?
A crane is a machine that lifts, lowers, and moves a load, usually with a hoist line, a boom or tower, and some combination of drums and sheaves. In construction, when most people say crane, they're really talking about a mobile crane - truck-mounted, rough-terrain, all-terrain, or crawler.
I start with that question before discussing a 100-ton Tadano crane because the category drives cost more than the name. A 100-ton all-terrain unit and a 100-ton rough-terrain unit can both be rated at 100 tons, but their roading requirements, tire costs, rental rates, and job site mobility are completely different.
How do I find a Tadano crane dealer worth trusting?
I would rather buy from a dealer with a working parts counter than one with a slightly lower quote. I learned that lesson on a backup rental unit a few years ago, not on a Tadano, but the principle stuck. We saved some money on the initial rate and then spent three weeks waiting on a part that should have been on the dealer's shelf. (Should mention: the machine was older, so the part was not covered by any warranty.)
Now when I compare Tadano crane dealer options, I ask four questions:
- How many technicians are trained on the specific model I'm considering?
- Do they stock common filters, sensors, and control parts locally, or is everything a special order?
- Can they show me the service record and load chart history for the actual crane?
- Will they put the configuration in writing, including counterweight and hook block?
The extra cost of a stronger dealer gets easier to justify when you calculate downtime. A dealer who can answer those questions is often cheaper over five years, even when the first quote is higher.
Is a 100-ton Tadano crane the right size for typical project work?
The 100-ton class is popular for a reason: it handles the awkward middle of the market. For our work - setting process skids, hoisting mezzanine steel, and placing equipment on existing foundations - it gives enough capacity at a working radius without forcing us onto a crawler.
That said, never buy the number in the model name. Buy the load chart at the radii where you actually work. When I review a 100-ton Tadano crane specification, I look for capacity at 30, 50, and 70 feet with a specific counterweight configuration. If the quote says only 100-ton crane, that is not a quote; it is a placeholder.
For some jobs, an 80-ton model will make the same lift for less money. For other jobs, I need a different class because the 100-ton chart runs out at a long radius. The class is a starting point, not a conclusion.
What does LMC truck mean on a crane listing?
Honestly, LMC truck is not a standardized term. In crane equipment listings, LMC can stand for load moment control or load moment computer, and truck usually points to the truck-mounted crane setup. Some sellers use the phrase loosely, so I treat it as a specification to verify, not a feature to pay extra for.
If LMC means load moment control, it is a safety-related system that monitors boom angle, radius, and load moment. I still ask for the calibration date and the latest inspection report. A control system only helps if it is working and correctly set for the machine configuration in the listing.
Should I pay extra for a paddle attachment?
The first time I saw paddle attachment on a crane quotation, I asked our operations manager what it meant. In the listings I've seen, it usually refers to a paddle-style hand control for precise hoist and swing functions. Another seller might use the same word for a different tool, so I do not assign value until the dealer identifies the exact attachment and confirms it is correct for that crane model.
A paddle control can be useful, but it does not increase lifting capacity and it does not change the load chart. I would not pay a big premium based only on the name. From a cost perspective, an attachment earns money only if it improves utilization. If it sits in a crate for 18 months, it was expensive at any price.
Why do I focus on five-year cost instead of the lowest quote?
Because the rest of the invoice arrives later. When I started in procurement, I chose a lower quote and wrote a small victory note in my budget file. (Should mention: I also missed the extra freight and the fact that the warranty started before commissioning.) I don't do that anymore.
Now I put every expected cost into a simple model: purchase or rental rate, transportation, commissioning, operator training, parts availability, warranty start date, and expected downtime. For owned units, I run the model over five years. For rentals, I run it over the project duration.
This approach worked for us, but we're a regional contractor with fairly predictable jobsites. If you're running a national heavy-civil fleet with cranes that relocate every two weeks, your costs will be in different places. The method still helps; the variables change.
