Furukawa Unic UR800 Parts Catalog – 147 Pages of Factory Spec Data

I’ve seen it a hundred times. A guy pulls a crane into the shop, needs a replacement boom assembly, and orders a part from some third-party catalog based on a blurry photo. Then it doesn’t fit. Then he’s stuck waiting a week while the machine sits. That’s a waste of billable hours. If you’re working on a Furukawa Unic UR800 series, you need the Furukawa Unic UR800 Parts Catalog – the actual 147-page factory document, not some scanned copy with missing pages. This is what the factory uses to identify every bolt, bushing, and sheave on that crane. The catalog is built around serial numbers, interchangeability codes, and genuine part numbers. Skip any of that and you’re guessing. I don’t guess, and neither should you.

Parts Catalogs: Not Just a Parts List

This isn’t a repair manual with torque specs – it’s a parts catalog. That means every page is dedicated to showing you exactly which part number goes where, in what quantity, and whether later revisions are backward-compatible. The UR800 series covers serial number E100001 and up. If you don’t verify your crane’s serial number from the specification plate, you’re ordering blind. The catalog uses a key number system (like 1-43) that ties each illustration to a row in the parts list. You get part number, part name, quantity, serial number applicability, and a mark column showing interchangeability. That’s the difference between getting the right sheave assembly and ordering a part that won’t bolt up.

Serial Numbers – The One Thing You Cannot Skip

Every crane has a serial number stamped on the specification plate fixed to the column. The catalog explicitly says it applies to the UR800 series from No. E100001~. If you’re working on a machine older than that, this manual won’t apply. Even within the same model, Furukawa Unic made running changes. The mark column in the parts list tells you: O means old and new parts are interchangeable; Q means new parts can replace old but not vice versa; X means not interchangeable. Ignore those marks and you’ll order a part that physically won’t fit. I’ve watched guys waste an afternoon because they didn’t check the serial column. Don’t be that guy.

Key Number System: Breaking Down the Indices

When you open the catalog, you’ll see exploded diagrams with key numbers like A-1 or B-2. These are not random. A indicates an assembly part; A1, A2, A3 are component parts under that assembly. The list shows the hierarchy: assembly, sub-assembly, then component. For example, on page 3 of the catalog (not that you need a specific page number – the whole system is consistent), a Boom Ass’y might have key number A-1 with a part number 0146 24000, and under it you’ll find A-1-1 for the bolt (7161 06030) and A-1-2 for the spacer (0215 21020). Every quantity is per assembly. This is how you order the correct number of bushings and seals without buying extras that sit on the shelf for years.

Genuine Parts vs Aftermarket – No Warranty on Cheap Imitations

Page 4 of the catalog includes a note that I want every tech to read out loud: “Use UNIC GENUINE PARTS exclusively for servicing your crane. No warranty can be given on a trouble caused by using a part except genuine parts.” That’s not marketing fluff – that’s a direct warning from the manufacturer. I’ve seen aftermarket sheaves that didn’t match the groove radius, aftermarket bushings that galled within fifty hours. When you’re working on a hydraulic crane rated for lifting, the part has to be exactly what the factory spec calls for. This catalog gives you the genuine part number. You can walk into any Furukawa Unic dealer and order with confidence – if you bring the serial number and the part number from this manual. Anything else is a gamble with someone’s safety.

147 Pages of Factory Spec Data – What You Get

147 pages sounds like a lot, but every page is packed with information you cannot get from a third-party reprint. The catalog includes illustrations for every major assembly: boom, hoist, swing, outriggers, control valves, and hydraulic components. Each illustration has callouts with key numbers that match the parts list. The list includes part numbers (like 0146 24000), quantities (like “1 set”), and the mark column I mentioned. There’s also a section explaining how to order parts: you need crane model, assembly name, part number, serial number, part name, and quantity. Write them down before calling the dealer. Makes the conversation take thirty seconds instead of fifteen minutes.

Check Out Other Furukawa Unic Manuals

If you work on other Unic crane models, I recommend these factory catalogs as well: Furukawa Unic URW295C1UR Parts Catalog – 256-Page Factory Spec for the smaller capacity rigs, Furukawa Unic URV500 Parts Catalog – OEM Spec, 471 Pages for the larger variable‑reach models, and Furukawa Unic URW370C2UR Parts Catalog – OEM Spec, 292 Pages for the intermediate class. Each one follows the same key number system and serial number identification. Once you learn the format, you can jump between them without confusion. For a deeper look at how OEM documentation standards are maintained across the Automotive Industry Overview, the Wikipedia article gives context on why factory specs matter. Also the Automotive Industry Overview is a good starting point for understanding parts numbering conventions in heavy equipment.

Frequently Asked Questions

What serial numbers does this manual cover?

The manual covers the UR800 series from serial number E100001 onward. Check the specification plate on the crane column to confirm.

Can I use aftermarket parts with this catalog?

The catalog lists only genuine UNIC part numbers. The manufacturer explicitly states no warranty is given if you use non‑genuine parts. For safety and fit, stick with the factory numbers.

How are parts listed in the catalog?

Each assembly has an exploded diagram with key numbers. The corresponding parts list includes part number, name, quantity per assembly, serial number applicability, and interchangeability marks (O, Q, X, etc.). Sub‑assemblies are nested under the main assembly key.

Yes, the catalog is printed in English by Furukawa Unic Corporation. The introduction and all parts lists are in English. Illustrations are universal.

When you need to order a part for the UR800, don’t guess. Get the factory document that tells you exactly what goes in, what serial range it fits, and whether it’s interchangeable. Access the Factory Manual now and keep it on your tablet or printed in the shop binder. That’s one less headache on the next crane job.
