Furukawa Unic URV346-C 2010 Operators Manual

I’ve been in this trade long enough to know that the difference between a safe lift and a disaster is often a piece of paper. The Furukawa Unic URV346-C 2010 Operators Manual is that paper. 70 pages of factory-specified procedures, load charts, and maintenance intervals. Without it, you’re guessing the boom angle or the wire rope inspection criteria. I don’t guess. You shouldn’t either.

Factory Origin vs. Aftermarket Copies

This manual is printed by Furukawa Unic Corporation, Tokyo. It is the exact same booklet that ships with a new URV346-C. Aftermarket reprints often skip the placard section or crop the load chart. That matters when you need the exact boom angle limits. I’ve seen aftermarket manuals miss the emergency release procedure on page 4-4. That’s a liability. Stick with the OEM.

Operator’s Station: Controls, Load Charts, and Procedures

The Operator’s Station section covers the crane parts, controls, and every step of lifting. Page 2-14 holds the Maximum Load and Boom Angle Chart – you need that taped to the cab window. Sections 4-1 through 4-7 cover controls identification, operating instructions, general rules, and roading the unit. If you’re new to this crane, start with 4-2 Operating Instructions. That section explains the joystick patterns and emergency stops. Manual Transmission information is referenced in the ROADING section when you need to shift the crane’s travel. Don’t skip that.

Maintenance Schedule: Daily, Weekly, Monthly, Annual

Most crane failures start with skipped maintenance. This manual lays out a clear schedule. Daily checks include walk-around inspection, function inspection, and wire rope inspection. Weekly and monthly checks cover lubricating swing bearing and checking gear oil level. Annual checks include changing gear oil and checking swing bearing mounting bolts. The manual also recommends specific grease, gear oil, and hydraulic oil. For the crane’s drivetrain details, see Manual Transmission guidelines from the factory.

Safety Rules and Emergency Release

Safety starts on the first page of the manual. The safety rules are not suggestions – they are the legal operating parameters. The emergency release procedure on page 4-4 covers what to do if the crane loses power. That section includes hydraulic circuit diagrams and step-by-step manual overrides. The manual explicitly warns against unauthorized modifications. From the copyright page: “CHANGES OR MODIFICATIONS TO THE CRANE NOT EXPRESSLY APPROVED BY THE MANUFACTURER COULD VOID THE WARRANTY.” I’ll add: and could kill someone.

Who Should Own This Manual?

If you operate a URV346-C, this manual belongs on the cab shelf. If you maintain one for a rental yard or construction company, you need it for the periodic maintenance schedules. Mechanics: use it for the wire rope replacement criteria and hydraulic circuit troubleshooting. Beginners: do not operate this machine without reading Section 4 (Operations) first. Experienced operators: use the load chart to double-check your lifts. It applies whether you’re lifting pipe in a ditch or setting steel on a rooftop.

Does this manual include the load chart for all boom configurations?

Yes, the Maximum Load and Boom Angle Chart on page 2-14 covers all rated capacities for the URV346-C.

What maintenance checks are required daily?

Daily checks include the walk-around inspection where you inspect tires, lights, hydraulics, wire rope, and structural components for any damage or leaks. Next is the function inspection where you test the boom extension, winch, swing, and emergency brake to ensure they operate smoothly. The wire rope inspection is critical – look for broken strands, kinks, birdcaging, or corrosion that could cause failure under load. All these daily checks are listed in the manual with pass/fail criteria. Skipping them is not an option if you want to keep the crane safe and the warranty intact.
