FIAT Kobelco 7055-2 Technical Manual – What the Factory Actually Published

If you’re wrenching on a FIAT Kobelco 7055-2, you need the exact numbers the engineers used. Not a generic load chart from a website that copy-pasted data from a different model. This 23-page Technical Manual is the original factory document – the same one the dealer’s shop pulls from when you call for a spec. I’ve seen guys snap boom sections because they trusted a third-party reprint that listed the wrong jib angle. Don’t be that guy.

Page 2 gives you the full specification table: maximum rated load of 55 tons at 3.7 meters, engine details (Mitsubishi 6D24-TE1 at 169 kW / 1,800 rpm), rope speeds, and ground pressure. Want to know if a 32-ton hook fits with the 9.1-meter boom? That table tells you. Page 3 shows the overall dimensions – critical if you’re moving the machine on a lowboy trailer. The manual includes every attachment option: clamshell, vibro hammer, lift magnet, and the luffing tower configuration. This isn’t a “quick reference” – it’s the full OEM data set.

Crawler Crane Specifications: What’s on Pages 2–3

The manual opens with the 7055-2’s main specs. Lifting capacities are given in metric tons with the working radius – no rounding, no “derated for safety” guesswork. The original Japanese text (with SI units and traditional equivalents in braces) means you get the factory’s exact test data. For the engine, it lists the Mitsubishi 6D24-TE1 at 1,800 rpm. Wire rope diameters: main hoist φ22 mm, boom hoist φ16 mm. If you need the travel speed (2.2 km/h high, 1.4 km/h low) or the grading ability (40%, or 21.8 degrees), it’s right there. These are the numbers you rely on when setting up a lift plan or ordering replacement parts.

Boom and Jib Configurations: Factory Assembly Charts

Inside the manual you’ll find the complete boom and jib matrix for the crawler crane configuration. Booms from 9.1 meters up to 51.8 meters, with the option to add a luffing tower (21.0 to 42.4 meters). Jibs can be 6.1, 12.2, or 18.3 meters. The manual shows exactly which intermediate sections are compatible, which hooks (55t, 45t, 32t, 19t, or 6.6t ball) fit each configuration, and whether the side steps or wind speed meters are standard or optional. For the luffing tower, the tower booms and tower jibs are listed separately – don’t mix them up. This section is what keeps your crew safe when you’re working near power lines or in tight spaces.

Load Charts: Why Factory Data Matters

The load charts start on page 7 and run through page 20. They cover main boom, jib at 10° and 30° offsets, and luffing tower lengths from 21.0 m to 42.4 m. Each chart is a table of radius versus capacity – no interpolation needed. The manual even includes charts for “no main hook” jib configurations. I’ve been in shops where a tech used a load chart from a different model because “it looked close.” That’s how you buckle a track frame. This manual gives you the exact numbers the machine was certified with. If you’re operating in North America, you need these for your site-specific lift plan. The OSHA folks will want to see the OEM data.

23 Pages of Critical Specs – What You Get

Twenty-three pages. That’s all it takes to capture the essential safety and performance data for a 55-ton crawler crane. Page 1 is the machine identification and capacities. Pages 2–3 are the main specs and overall dimensions. Pages 3–4 show the boom and jib configurations. Pages 5–20 cover working ranges and load charts for every boom/ jib/ tower combination. Pages 21–22 list the attachments (clamshell, vibro, lift magnet) and the standard/optional equipment. No fluff, no marketing talk – just the factory’s engineering data. This is the manual you need if you’re rebuilding the undercarriage, replacing wire ropes, or verifying the machine’s rated capacity before a lift.

Audience Fit: Who Should Use This Manual?

This is for the owner-operator, the heavy equipment mechanic, and the workshop foreman who needs the original specs for a FIAT Kobelco 7055-2. If you’re a home garage enthusiast and you bought a retired 55-ton crawler crane for a project, this manual is your bible. Beginners? Don’t touch the boom without reading the load charts first. Professionals will appreciate the factory’s exact wire rope lengths and hook dimensions. The manual is in English and Japanese (dual-language on many pages), but the tables are universal. If you can read numbers, you can use it. For related models, check out the FIAT Kobelco W80 2004 Technical Manual – 46-Page OEM Factory Specs or the FIAT Kobelco 7055-3F Technical Manual – 24-Page Factory Specs. The FIAT Kobelco CK1600-II Technical Manual – 33-Page OEM Factory Specs is also available if you need specs for a larger model.

Source Validity: OEM vs Aftermarket

I trust factory manuals. Period. Aftermarket companies scan these things, blur out the original part numbers, and repackage them with sloppy translations. This 23-page Technical Manual comes from the original FIAT Kobelco PDF – the same file the factory uses to train technicians. Page 2 lists the engine serial number range and the torque converter model. Page 3 gives you the exact outer dimensions for transport. If you’re working on the drivetrain, understanding the Manual Transmission system is critical, but this manual focuses on the crane’s hydraulics and structure. The external link to Manual Transmission might help if you’re also servicing the truck carrier, but don’t confuse the two. This manual is the real deal – no reprints, no third-party additions.

Does this manual cover backhoe loader functions?

No. The FIAT Kobelco 7055-2 in this manual is configured as a crawler crane. If you need backhoe loader specs, you need the operator’s or service manual for the specific loader attachment. This is strictly the crane and lifting data.

What’s the engine model listed?

Mitsubishi 6D24-TE1 at 169 kW (230 PS) at 1,800 rpm. The manual includes the rated output and fuel consumption data on page 2.

How many pages are there?

23 pages, including the cover and equipment lists.

Can I use this manual for North American regulations?

Yes, but you need to convert the SI units to imperial. The manual uses metric (kN, t, m) with traditional units in braces. I recommend keeping the factory SI data on site for certification audits. The load charts are universal – they don’t change with region.

You don’t have time to chase down missing specs while a crane is sitting idle. Access the Factory Manual and get the OEM data on your tablet or printed out before your next lift. Twenty-three pages of the real thing beats a thousand pages of internet rumors.
