Furukawa Unic RC30R-3EA, RC30S-7 Parts Catalog – OEM Factory Spec You Can Trust

I’ve been wrenching on hydraulic equipment for 28 years, and nothing burns me up faster than a parts catalog that lists a part number that doesn’t exist. You order it, wait three days, and it’s wrong – wasted time, wasted money. This Furukawa Unic parts catalog is the real deal. 63 pages of factory-sourced part numbers, exploded diagrams, and ordering codes for the RC30R-3EA and RC30S-7 remote control devices. If you’re working on one of these UNIC cranes, this is the only parts list you should have on your bench.

Remote Control Device Parts Breakdown – What the Manual Shows

The core of this catalog is the exploded diagrams for the remote control unit itself. You get key-numbered illustrations that tie directly to the parts lists. Need a replacement joystick assembly? The illustration shows it, the list gives you the part number, quantity, and even serial number applicability. The catalog covers the RC30R-3EA and RC30S-7 models, both using the same remote control device with some differences in sub-assemblies. Page 5 starts with the remote control device overview – HP1, HP7,8, and the numbered callouts. You’ll see spacers, sheaves, bushings, grease nipples – every component down to the bolt.

How to Use This Parts Catalog – Key Numbers and Assembly Codes

Flip to page 3 and you’ll find the “How to Use” section. It explains the KEY No. system – for example, “1-43” points to a part in the illustration. The Parts No. column lists the Furukawa Unic part number, and the Parts Name column describes each component. The catalog distinguishes assembly parts from sub-assembly and component parts using a lettering system (A, A1, A2, etc.). That matters when you order – you don’t want to buy a whole assembly when you only need a bushing. The chart on page 4 tells you how to read the Mark column: circles, crosses, diamonds indicate interchangeability. This is the kind of detail that saves your Saturday.

63 Pages of Factory Part Listings – Nothing Missing

63 pages might not sound massive, but for a parts catalog this is plenty. Each page is packed: part numbers, quantities, cross-references. The catalog covers the entire remote control device including the receiver, transmitter, harnesses, and mounting hardware. Because it’s a genuine OEM publication from Furukawa Unic Corporation (Tokyo), every number matches the crane as it left the factory. Compare that to some aftermarket “compatible” list that guesses the thread pitch – you’ll get a stripped bolt every time. I won’t touch aftermarket parts catalogs; they’re a liability.

Ordering Genuine Parts – The Correct Procedure from the Source

The catalog includes a dedicated section on how to order service parts. You need the crane model, serial number, assembly name, part number, and quantity. It also tells you how to handle parts marked with the $ or X symbols – those indicate interchangeability. If you order a part marked X, you must confirm the crane’s serial number and manufacture date. Miss that step and you’ll get the wrong revision. The catalog also states plainly: use only UNIC genuine parts. No warranty on troubles caused by non-genuine parts. That’s factory talk, and I respect it.

Source Authenticity: OEM vs Aftermarket – Why This Catalog Wins

I’ve got a stack of aftermarket parts guides that look like they were scanned from a fax machine. Blurry part numbers, no serial number ranges, and quantities that don’t add up. This catalog is a direct scan of the original Furukawa Unic publication – PCRC-30R,30S199608A. The copyright page (page 2) shows the Tokyo address and fax number. Every page is legible, every number is crisp. If you’re a professional mechanic or a crane owner doing your own maintenance, you need this level of accuracy. You can find related manuals for other UNIC models like the Furukawa Unic URW295C1UR Parts Catalog – 256-Page Factory Spec or the Furukawa Unic URV500 Parts Catalog – OEM Spec, 471 Pages. For bigger cranes, the Furukawa Unic URW370C2UR Parts Catalog – OEM Spec, 292 Pages covers more ground. But for these RC30 remotes, this is the one.

Does This Catalog Cover the Entire Crane?

No. This is a parts catalog for the remote control device only. It does not cover the base crane engine, hydraulics, or structural components. For that you’d need the full crane service manual. But if your remote is acting up – intermittent signal, broken joystick, damaged cable – this catalog gets you the exact replacement part. The remote control unit on these UNIC cranes is a wear item, and having the factory part number saves hours of cross-referencing. I keep a copy on my tablet in the shop.

FAQ

Q: Can I use this catalog to find torque values?

A: No. This is a parts catalog, not a service manual. It lists part numbers, not repair procedures or torque specs.

Q: Does the catalog include wiring diagrams for the remote control?

A: It does not include electrical schematics. It shows exploded mechanical views of the control device assemblies and lists the individual components – switches, connectors, cables – but you won’t find wire colors or pinouts. You need the separate electrical troubleshooting manual for that.

Q: How do I know if the part I need is still available from Furukawa Unic?

A: The catalog shows part numbers and indicates interchangeability with symbols. But availability changes over time. Contact your nearest UNIC dealer with the part number from this catalog. The ordering instructions on page 4 explain exactly what info the dealer needs: crane model, serial number, assembly name, part number, and quantity.

Q: What’s the difference between the RC30R-3EA and RC30S-7 in this catalog?

A: Both use the same remote control device catalog, but the crane models differ in boom length and capacity. The parts catalog lists the same remote unit for both, with certain sub-assembly variations noted by serial number ranges. Check the “SERIAL No.” column on each parts list page – it tells you which crane the part fits. If you have an RC30R-3EA, sort by the RM prefix; for RC30S-7, look for the appropriate serial break.

Don’t waste another afternoon guessing part numbers that don’t fit. Access the Factory Manual for the Furukawa Unic RC30R-3EA, RC30S-7 Parts Catalog and get the OEM data you need. I’ve got it on my shop computer, and it’s saved me more than once. If you work on UNIC cranes, this is the parts book you want open. Automotive Industry Overview Automotive Industry Overview
