Tadano FAUN RTF 40-3 Technical Manual – OEM Load Charts and Factory Specifications

If you operate a Tadano FAUN RTF 40-3 and you’re still using a third-party load chart app or a dog-eared photocopy from the previous owner, you are taking a risk I’ve seen cost shops north of $50k in damage. I’ve torqued enough chassis bolts and watched enough crane mishaps to tell you: the difference between a safe lift and a tipped rig is often a single line in a load rating chart. This Tadano FAUN RTF 40-3 Technical Manual is the exact document that left the factory floor – 21 pages of lift capacities, outrigger reaction forces, dimensions, speeds, and telescoping sequences. Nothing added, nothing guessed.

Check the Outrigger Base Before You Lift

Page 4 and page 5 of this manual show two distinct outrigger base settings: 20.60 ft and 15.42 ft. Each produces a different lifting capacity at the same boom length and radius. For example, at a 30 ft radius with the boom extended to 52.82 ft, the capacity on the 20.60 ft base is 23.6 (1,000 lbs) while on the 15.42 ft base it drops to 22.4. That’s a 1,200-pound swing that a generic chart won’t tell you. The manual prints these values in clear tables along with the SAE J765 compliance statement. You need to verify your machine’s serial number (40321 per the cover) and outrigger setup before setting the load.

Load Rating Charts for the RTF 40-3

The core of this manual is the load rating chart section – pages 4 and 5 cover the full telescopic boom range from 30.25 ft to 98.42 ft, with working radii from 9 ft to 90 ft. Each cell gives the maximum lift in 1,000 lbs. A star (*) on the 30.25 ft boom at 9 ft radius indicates 88.0 (88,000 lbs) with additional lifting equipment. That detail is easy to miss if you’re working from a copy that bleached out the symbol. The manual also includes the telescoping sequence percentages (Tel.1/2/3 and a code) so you know which sections are extended and by what amount – critical for matching the chart to your actual boom configuration.

What Do the Telescoping Sequence Codes Mean?

Under each load chart you’ll see a small table labeled “Telescoping sequence %”. For the 20.60 ft outrigger chart, the sequence shows 0/0/0 for 30.25 ft boom, 50/50/50 for 52.82 ft, and 100/100/100 for the 75.47 ft and 98.42 ft booms. But note the code row: for the longer booms the code is 11/12, while for the 15.42 ft chart it shifts to 16/17. These codes correspond to specific hydraulic control sequences that govern which section extends first. If you override that sequence with a manual override valve, your load chart becomes invalid. The manual gives you the factory sequence – don’t guess.

Dimensions and Weights: Know Your Machine’s Footprint

Page 3 of the manual lays out the physical dimensions: overall length 11,095 mm, width 2,700 mm, height 3,850 mm (with 16.00 R 25 tires). Axle loads listed as 11.85t plus 11.60t equals 35.3t total. Ground clearance at 100 mm, approach and departure angles marked. If you ever need to transport this crane on a lowboy, these numbers are what the DOT inspector will check. The manual also shows the 6×4 and 6×6 configurations – make sure you’re reading the right column for your chassis.

21 Pages of Factory Specs – No Aftermarket Shortcuts

Every page in this Tadano FAUN RTF 40-3 Technical Manual is a direct OEM reproduction. No rewritten paragraphs, no “interpreted” torque values, no reprints that lost resolution. The original file name – FAUN_RTF_40-3_Technical_Manual_en-de-fr-44513007388.pdf – confirms it’s trilingual (English, German, French) and sourced from Tadano’s own documentation system. I’ve seen shops lose insurance claims because their load chart didn’t have the serial number or the SAE J765 stamp. This manual has both, on every chart page.

If your work involves other driveline components, the Manual Transmission and Manual Transmission sections on Wikipedia can supplement your understanding of powertrain fundamentals, but for crane-specific lift data, this manual is the only source you should trust.

Does this manual include repair procedures or only load charts?

It is a technical manual focused on ratings and specs – load charts, outrigger reaction forces, dimensions, weights, speeds, and telescoping sequences. It does not contain step-by-step repair instructions. For repairs, you want the separate service manual.

Can I use these charts for a different RTF 40-3 serial number?

The charts are serialized to machine number 40321. While the values are representative for most RTF 40-3 units, Tadano FAUN updates charts when boom or counterweight changes occur. Always use the manual with your specific serial number. Using the wrong serial can result in a lift capacity error that exceeds safe margins.

Stop borrowing a dog-eared copy from the operator in the next yard. Access the Factory Manual and have the OEM data on your tablet or printed binder before you make that next pick.
