FIAT Kobelco CK1750 Technical Manual – 30 Pages of Factory Lift Specs

You’re working on a CK1750, and the load chart says 175 tons at 16 feet, but you don’t have the factory documentation to back it up. That’s a liability. I’ve seen shops try to guess boom angles and end up with a wrecked crane or worse. This 30-page FIAT Kobelco CK1750 Technical Manual gives you the exact numbers – no aftermarket interpretation. I’m Mike Callahan, and I’ve torqued plenty of stuff that’d flatten a pickup truck. For a crane this size, you need the original OEM specs.

Lifting Capacities and Working Ranges (Page 1–2)

Page 1 lists the maximum lifting capacity: 175 US tons at 16 ft radius. The maximum boom length is 270 ft, and with a fixed jib you can hit 340 ft total (240 ft boom + 100 ft jib). Page 2 shows the working range diagram with straight boom and fixed jib, including height above ground and radius from center of rotation. You get curves for every boom length from 60 ft to 270 ft, plus jib combinations up to 100 ft. That data is what you need to plan a lift without guesswork.

Boom and Guy Line Arrangement (Page 3)

Page 3 lays out the straight boom rigging for every length from 60 ft to 270 ft. Each arrangement specifies the location of boom inserts, cable rollers, midpoint suspension points (marked E), and guy line attachment points. The table includes the symbol key (A, B, C, D, E, F, PS) and their distances. If you mis-rig the guy lines on a 270 ft boom, you’re asking for a bend. This page keeps that from happening.

Jib and Jib Guy Line Setup (Page 4)

Page 4 covers the jib arrangement for lengths of 40 ft, 60 ft, 80 ft, and 100 ft. It shows the equalizer sheave, strut dimensions, and guy line diameters (11/32 inch) with exact lengths in feet-inches. Two offset angles are documented: 10° and 30°. The note at the bottom warns that for most efficient use, the guy line arrangement must be observed exactly as shown. That’s not a suggestion – it’s a safety requirement.

Why Factory Documentation Matters for Crane Safety

I’ve run across third-party reprints that fudge the numbers on boom angles or leave out the jib guy line lengths. On a CK1750, being off by 15 ft on a guy line means the jib can fold under load. This manual is the original FIAT Kobelco print – no reprints, no scanned copies with lost resolution. The 30 pages are clean, OEM-issued data. If you’re the guy responsible for rigging this crane, you want the same specs the factory test engineers used. That’s what you get here.

What the 30 Pages Cover – Audience Fit

This technical manual is for equipment owners, crane operators, and shop foremen who need the factory lifting capacities and rigging dimensions. If you’re a DIY farmer running a CK1750 on your land, you still need these numbers before you lift a 150-ton silo section. The manual doesn’t include engine overhaul procedures or electrical diagrams – it’s a dedicated lift capacity and structural arrangement guide. For related FIAT Kobelco models, check 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 another good reference if you run the smaller crane.

The CK1750 uses a Manual Transmission – understanding shift points and clutch adjustment is critical for safe operation. If you’re rebuilding that transmission, refer to the Manual Transmission basics as background, but always use the factory specs for clearances and torque.

Does this manual cover multiple model years?

It covers the FIAT Kobelco CK1750 specifically; no year range is listed. Factory data is model-specific.

Does it include wiring diagrams or hydraulic schematics?

No, this is a crane technical manual focusing on lifting capacities, boom/jib arrangements, and guy line dimensions. For electrical or hydraulic system troubleshooting, you need a separate service manual. The 30 pages here are dedicated to structural rigging and load charts – that’s what keeps your machine stable during lifts. I’ve seen guys try to use a combined manual that buries the crane specs inside engine chapters. This one cuts the crap and gives you the numbers you actually need on the jobsite.

Are engine torque specs provided?

The manual does not list engine or fastener torque values; it’s a lifting-capacity and arrangement guide. For engine torque specs, get the engine service manual.

Can I use this manual for a CK1750 with a fixed jib at 30° offset?

Yes, page 4 explicitly covers jib arrangement for offset angles of 10° and 30°, with guy line lengths for each jib length (40, 60, 80, 100 ft). The diagrams on pages 2 and 4 show the working range for fixed jib configurations up to 340 ft total length. You need to follow the exact guy line setup shown for your boom length and offset angle – the table on page 4 gives dimensions for the boom-side jib guy lines (C and D+E) depending on boom length groups. Ignoring those details can overload the jib structure.

You need a manual that doesn’t waste your time with fluff. This 30-page FIAT Kobelco CK1750 Technical Manual puts the factory lifting capacities and rigging specs right on your bench. No aftermarket interpolation. Access the Factory Manual now and keep your crane work safe and to spec.
