FIAT Kobelco SL4500 Technical Manual – 64 Pages of Factory Specs

You’ve got a SL4500 on the job site and you’re guessing at the lifting capacity for a 256 ft luffing jib combination. That’s how bolts get stretched and booms come down. I’ve seen it. This FIAT Kobelco SL4500 Technical Manual is the factory document—64 pages of what the engineers wrote, not some aftermarket rewrite. If you’re running a 440-ton crawler crane, you need the real numbers. Not a PDF that says “refer to the manufacturer.” Here it is.

Configuration and Specifications: What the First 4 Pages Give You

Page 1 spells out the standard configuration: max lifting capacity 440 US ton at 18 ft, max boom length 315 ft, max luffing jib combinations 256 ft + 217 ft. Page 2 breaks down the STD, HL, and SHL luffing boom capacities. The Hino diesel engine spec—E13C-UV, 429 HP at 2,000 rpm, 1,218 lb-ft torque at 1,300 rpm—is on page 4. Six variable displacement piston pumps, two for each circuit. That’s the kind of data you need to verify before you start a lift. If your pump drive goes out and you don’t have the spec, you’re chasing parts for a week.

Fuel tank capacity: 158 US gal. Batteries: two 12V 136Ah in parallel. This is the stuff that keeps the machine running. FIAT Kobelco W80 2004 Technical Manual – 46-Page OEM Factory Specs covers a smaller machine, but the same attention to detail.

Boom and Jib Arrangements: Standard, Heavy Lift, Super Heavy Lift

The manual devotes separate sections to each configuration. Standard boom and jib arrangements start on page 7, working ranges on page 9. Luffing boom supplemental data on page 14, luffing jib on page 15. Then the lifting capacities—page 19 for luffing boom, page 21 for long boom, page 23 for luffing jib. You don’t estimate a 250,200 lb lift at 32 ft. You read the chart. The Heavy Lift section begins on page 29 with boom and jib arrangements, working ranges on page 31, capacities on pages 35 and 39. Super Heavy Lift starts on page 45. Each section has its own working range diagram and capacity table. That’s three separate lifting configurations with their own structural limits. Ignore that and you’re overloading the boom.

FIAT Kobelco 7055-3F Technical Manual – 24-Page Factory Specs is a smaller manual, but this SL4500 manual is the real deal for heavy iron.

64 Pages of Factory Data: Why Page Count Matters

64 pages doesn’t sound like a lot until you realize each page is packed with dimensioned drawings, capacity tables, and assembly steps. The transportation plan on page 59 shows you how to move this 440-ton crane without tearing down the wrong section. Assembly and disassembly on page 60—that’s where guys get hurt if they skip the sequence. Parts and attachments on page 61 rounds out the document. There’s no fluff, no reprints, no generic illustrations. This is the OEM print. FIAT Kobelco CK1600-II Technical Manual – 33-Page OEM Factory Specs is another example of the same factory source.

Does This Manual Cover the Lifting Capacities for All Configurations?

Yes. The table of contents lists luffing boom lifting capacities (page 19), long boom (page 21), luffing jib (page 23), then heavy lift versions (pages 35, 39), and super heavy lift (pages 49, 53). Each capacity chart is tied to a specific boom length and jib combination. For example, the STD luffing jib max lift is 244,000 lbs at 55 ft with a 217 ft + 217 ft combination. The HL luffing jib max is 248,200 lbs at 55 ft with a 236 ft + 217 ft combination. You need the right chart for the right configuration. The manual gives you that.

Period.

Why OEM Documentation Beats Aftermarket for This SL4500

I’ve seen aftermarket manuals that list the wrong torque for the pump drive bolts. On a 440-ton crane, that’s a lawsuit. This FIAT Kobelco SL4500 Technical Manual is the original factory document. The specs come from the same engineering department that designed the machine. The wiring diagrams, hydraulic schematics, and capacity tables are not redrawn or reinterpreted. If you’re working on a crane that can lift 881,800 lbs with the STD luffing boom, you don’t want a third-party summary. You want the OEM print. That’s what AutoRepairManuals carries—the largest collection of OEM shop manuals in North America. Manual Transmission is a different topic, but the principle is the same: factory data is the only data you can trust. Manual Transmission

Can I use this manual for a SL4500 with a different boom configuration?

Yes. The manual includes STD, Heavy Lift, and Super Heavy Lift configurations. Each has its own capacity charts and working ranges. You pick the section that matches your machine’s setup.

What if I need the torque specs for the pump drive assembly?

The manual does not list torque values for every fastener. It covers the machine’s lifting capacities, dimensions, engine specs, and assembly procedures. For internal engine torque specs, refer to the Hino E13C-UV service manual. The SL4500 manual focuses on the crane structure, hydraulic circuits, and lift charts. That’s where most mistakes happen—overloading or misassembling the boom. The manual gives you the safe limits.

If you’re maintaining or operating a FIAT Kobelco SL4500, you need the numbers that came from the factory. Access the Factory Manual from AutoRepairManuals and keep it on the tablet in the cab. Your crew will thank you, and your insurance adjuster will sleep better.
