Tadano Cranes, 55-Ton Load Charts, Scissor Lifts, Truck Tires, and Crane Flies: An Admin Buyer's FAQ

I'm the office administrator for a 300-person construction services company. I manage equipment rentals and vendor orders—roughly $250,000 annually across 12 vendors. I report to both operations and finance. I'm not a crane operator or engineer, so I can't speak to lift planning. What I can tell you is how these questions show up in procurement, invoices, and site paperwork.

Here are the questions I actually get from project managers, AP, and new hires.

What should I know before I request a Tadano crane?

If someone sends a request for tadano with no model, I ask for five things: capacity, boom length, outrigger setup, counterweight, and site access. Tadano makes all-terrain, rough-terrain, crawler, and lattice boom cranes. Since Tadano acquired Demag mobile cranes in 2019, you may see Demag-related parts and service in the same support network. Don't book by tonnage alone. A 90-ton class crane may not lift 90 tons at every radius. I ask for the lift plan, site address, and the exact load chart page the operator wants. That's prevention over cure: 10 minutes of questions beats a stopped job or a rejected invoice.

How do I read a Tadano 55 ton crane load chart without getting lost?

You usually don't need to read it like an operator. You need to verify it exists, is current, and matches the machine. A Tadano 55 ton crane load chart is configuration-specific: boom length, counterweight, outrigger spread, radius, and lift angle all change the capacity. According to Tadano's official product support pages (tadano.com), load charts are model- and configuration-specific. OSHA's crane standard (29 CFR 1926.1400) also requires following the manufacturer's load charts and operating instructions. So when a vendor sends a chart, check the model, serial number or unit number, and revision date. I'm not a lift planner, so I do not sign off on capacity. I just make sure the right document is attached to the rental packet.

Is a Tadano 90t crane the same as any 90-ton crane?

Not exactly. A Tadano 90t crane is usually shorthand for a 90-tonne-class mobile crane, but capacity class is only a starting point. Two 90-ton cranes can have different boom lengths, axle loads, tire sizes, and setup requirements. For road permits, site access, and truck tires, those details matter. To be fair, the day rate is often similar across brands. But the real cost can hide in permits, escorts, mats, and whether the crane can fit through the gate. I ask for the crane's travel dimensions and axle weights before I approve anything. That's saved us from at least one canceled mobilisation (this was back in 2023).

What is a scissor lift, and when should I ask for one instead of a crane?

What is a scissor lift? It's a mobile elevating work platform that raises a platform vertically using a scissor mechanism (i.e., a platform that goes straight up, not a crane). It's usually for indoor or slab work where people need to reach height, not for lifting heavy loads. A crane lifts material; a scissor lift positions people and tools. If a foreman asks for a crane just to get two electricians to a ceiling, I ask whether a scissor lift or boom lift is safer and cheaper. Granted, scissor lifts need a level surface and clear overhead hazards. But for a 20-foot interior task, they're often the right call. Check the platform capacity and whether the site needs a trained operator. I'm not a safety expert—your site safety lead owns that call.

Do truck tires really matter on a crane rental?

Yes, especially for mobile cranes and haul trucks. Truck tires affect axle load, ground pressure, road permits, and whether the crane can travel on site. A worn tire or mismatched tire can fail an inspection or delay mobilisation. According to NHTSA, tires manufactured after 2000 carry a 4-digit DOT date code—the first two digits are the week, the last two are the year. I note the date code on any truck tires we buy or rent. I'm not 100% sure every rental yard tracks this, but a good one will. If the tires look cracked or the date code is old, I ask for a replacement before the unit leaves the yard. That's cheaper than a roadside call.

What is a crane fly—and why does it show up in crane searches?

A crane fly is an insect that looks like a giant mosquito. It usually doesn't bite. It has nothing to do with Tadano cranes, except the name. If you're searching 'crane fly' because you saw one on a job site, it's a pest nuisance, not a lifting hazard. If you're searching it because your SEO report mixed it with crane keywords, welcome to my world. I keep a note for new admins: 'crane fly = bug; crane = machine.' Don't hold me to this, but I think the confusion comes from the long legs looking like a lattice boom. Check with pest control if they're swarming; check with your crane vendor if you need a load chart.

What's the one checklist item most buyers miss?

Most buyers focus on the day rate and completely miss the documentation packet. The question everyone asks is 'what's your best price?' The question they should ask is 'what's included, and what paperwork comes with it?' For cranes, that means load chart, inspection certificate, operator certification, insurance, and permit responsibilities. For scissor lifts, it means annual inspection and operator training. For truck tires, it means DOT date codes and load ratings. In 2022, I found a great price from a new vendor—$600 cheaper than our regular supplier. They couldn't provide a proper invoice (handwritten receipt only). Finance rejected the expense report. I ate $600 out of the department budget. Now I verify invoicing and documentation before placing any order. 5 minutes of verification beats 5 days of correction. That's kinda the whole point of prevention over cure.

How do I verify a Tadano dealer or service provider?

Start with Tadano's official site (tadano.com) or the Tadano parts portal. Ask for the dealer's location, service radius, factory-trained technician certificates, and parts availability. If they claim to service Demag mobile cranes, ask how they handle post-2019 integration. Don't attack competitors; just compare response time, documentation, and warranty terms. I keep a simple vendor scorecard: quote accuracy, invoice quality, response time, and whether they send the right load chart the first time. After 5 years of managing these relationships, I can tell you that the cheapest quote rarely wins after you add rework. I usually consolidate to fewer vendors who can prove they document the work. That's not glamorous, but it keeps operations and finance off my back.
