Tadano ATF 90G-4 Technical Manual

You have a 110-ton all-terrain crane sitting in the yard and no reliable specs to set it up. That gets men killed. I’ve seen guys guess at reeving patterns and lift capacities because they were working off a photocopy from three machines ago. The Tadano ATF 90G-4 Technical Manual puts the factory data back in your hands – 24 pages of the exact diagrams, dimensions, and working limits that Tadano printed for the ATF 90G-4. No reprints, no aftermarket interpretation, just the original OEM document.

24 Pages of Factory-Approved Data

This isn’t a thick service manual, and it’s not meant to be. It’s a technical reference that covers the machine’s dimensions (Imperial units – feet, inches, pounds), working speeds, lifting heights, and rope specs. Page 1 gives you the crane identification and model designation. Page 3 lists the weights, working speeds (0–2 rpm swing, -1° to +82.4° boom angle), rope diameter and length (0.70″ / 755′ each for main and auxiliary winch), and maximum single-line pull of 12,364 lbs. You need to know if your boom extension is within safe ranges? Those lift height curves are on page 4. Every number came from Tadano’s engineering department – not from a third-party scanning a copy of a copy.

Working Speeds and Rope Limits: Why OEM Matters

Look at the working speed table on page 3. It shows you the hoist speeds (0–377 ft/min), the maximum permissible line pull (12,364 lbs), and the number of sheaves for each load configuration (Type 69.4 ton, Type 44.1 ton, etc.). An aftermarket data sheet might round those numbers or omit the “subject to change” notice that Tadano prints right on the page. When you’re hanging 110 tons on the hook, rounding errors are not acceptable. This manual gives you the exact values, including the note that maximum permissible line pull is affected by wire rope strength – a warning that saves you from snapping a cable on a heavy pick.

Does This Manual Cover the Entire Crane?

It covers the overall machine dimensions, tire options (445/80 R 25 or 525/80 R 25), ground bearing pressures, and the lifting height chart. If you’re looking for engine overhaul procedures or hydraulic pump rebuild specs, this isn’t that manual. You need the full TADANO ATF 90G-4 Operators Manual”>Operator’s Manual for daily operation and the Tadano ATF 90G-4 2011 Parts Catalog”>Parts Catalog for exploded views. But if you’re setting up the crane on site, checking your boom extension limits, or verifying rope reeving, this technical manual is the one you want on the tablet in the cab.

Lift Capacity Charts: OEM vs Generic

The lift capacity chart on page 4 is printed with the crane’s exact configuration – 360° rotation, outriggers set, specific counterweight. A generic chart that says “similar to Tadano ATF 90G-4” might be close enough for a backyard project, but not for a worksite where OSHA and your insurance require documented specs. This manual is the document you pull out when an inspector asks for proof of working limits. It’s an original OEM file, not a scanned reprint.

Source Authenticity: Why You Can Trust This PDF

This file came from Tadano’s distribution channel. 24 pages, file name Tadano_ATF_90G-4_Technical_Manual_en-44413007375.pdf – you can see the original structure. I’ve been in the business long enough to know that a manual printed from a third-party site often has missing pages, wrong torque values, or smeared diagrams. This one has clean vector graphics and the “Subject to change without prior notice” disclaimer that protects both the manufacturer and the user. If you need additional operating instructions, check the Tadano ATF 90G-4 Operators Manual – 968 Pages of Factory Specs”>Tadano ATF 90G-4 Operators Manual – 968 Pages of Factory Specs for the complete set of procedures.

Manual Transmission and Drivetrain Specs

The crane’s carrier uses a manual transmission – you’ll find driveline dimensions and axle loads listed in the technical manual. For more on manual transmission theory and maintenance, refer to this external resource: Manual Transmission”>Manual Transmission. This is not a transmission rebuild guide, but it gives you the weight distribution and wheelbase numbers you need for transport permits. Use the manual transmission specs alongside the lifting charts to set up your outrigger pads correctly.

If you’re also working on other Tadano machines, check out the external authority link: Manual Transmission”>Manual Transmission – it covers the same transmission systems found in many all-terrain cranes.

FAQ – Common Questions About This Manual

What is included in this 24-page technical manual?

Overall dimensions, working speeds, lift capacity charts, rope specs, tire options, and dimensional drawings with Imperial units. No maintenance or repair instructions.

Does this manual include step-by-step repair procedures?

No. This is a technical data manual – it gives you the factory numbers for setup and operation. For repair procedures you need the separate service manual. But having the OEM specs means you can verify that your machine is operating within its design limits before you start any repairs. For example, if your boom doesn’t extend to its full 168 ft, the lift height chart on page 4 tells you the expected angles and lengths. Without that chart you’re guessing whether the boom is short or the sensor is wrong. This manual eliminates that guesswork.

Can I use this manual for a different Tadano model?

No. This is specific to the ATF 90G-4. Using it for a different model can cause overload conditions or incorrect setup.

Is this an original OEM manual or a reprint?

Original factory file – the PDF matches Tadano’s internal technical document. No reprint or third-party copy.

You’ve got a 24-page document that contains the exact specifications Tadano printed for the ATF 90G-4. It’s the difference between setting up by feel and setting up by the book. If you operate or maintain one of these cranes, you need this on your tool tablet. Access the Factory Manual now and keep it with the machine.
