Zoumlion RT55 2013 Technical Manual – Load Chart and Safety Data

You are running a Zoumlion RT55 2013 Technical Manual on a job site. The load indicator is flashing, the ground is uneven, and the operator is looking at you for the rated load numbers. You don’t guess – you read the factory manual. This 50-page Zoumlion RT55 2013 Technical Manual is the only document you should trust for boom loads, outrigger float capacities, and safe setup procedures. Aftermarket copies skip the hazard labels and definition tables. That gets people killed.

This manual comes straight from Zoomlion Heavy Industry. It’s the same one that ships with the crane. The operator is required by the manufacturer to keep it in the cab. If you’re buying a used RT55 or adding a backup copy, this is the edition from December 2013. No reprints, no third-party scans.

Page 5 lays out the hazard indicators: DANGER, WARNING, CAUTION, ATTENTION, NOTE, and IMPORTANT. Each one has a specific meaning – death, injury, property damage, or tip. You need to know the difference before you pick up a load.

Main Boom Rated Loads and Outrigger Setup

Chapters 4 and 5 cover main boom rated loads. Chapter 4 applies when all outriggers are less than half extended. Chapter 5 applies when outriggers are fully extended or on tires. Each chapter has SET-UP and OPERATION sections. The load charts are not interchangeable. Use the wrong chart and you exceed the crane capacity at that configuration. The manual tells you exactly which chart to read based on outrigger position. Don’t skip the definition section (1.6) – it explains what terms like “boom angle” and “working radius” mean on this specific model.

Does This Manual Cover Hoist Tackle and Tire Pressures?

Yes. Section 1.1 is the hoist tackle chart. It lists the number of parts of line and corresponding maximum loads. Section 1.2 is the tire inflation chart. Underinflated tires change the stability of the crane. Use the factory numbers – not generic tire pressures. Page 1 of the manual shows the load ratings edition and confirms it’s for the RT55 Rough Terrain Crane. Check the tire inflation before any pick on rubber.

50 Pages of Factory Specs – What You Get

Fifty pages. That includes the title page, safety chapter (pages 4-5), chapter 1 (hoist tackle, tire inflation, weights, outrigger float load, general, definitions, setup, operation), and chapters 4 and 5 (main boom rated loads). Every page is from the OEM. No aftermarket interpretation. You get the exact load numbers that the crane was tested to. The manual also lists maximum outrigger float load (section 1.4). That number determines what cribbing you need under the floats. Ignore it and the outrigger can punch through the ground.

Check the Maximum Outrigger Float Load Before Every Lift

Section 1.4 gives the maximum outrigger float load. That’s the force pushing down on each pad. It’s not in the operator’s memory – it’s in the book. Use that number to calculate ground-bearing pressure. If the soil is soft, you need larger cribbing or a crane mat. The manual doesn’t give you mat sizes – that’s your job. But it gives you the starting number. Without it, you’re guessing how much force the ground has to hold.

Safety Information: DANGER, WARNING, CAUTION Labels Explained

Page 5 defines the hazard indicators. DANGER means death or injury if you don’t prevent it. WARNING means possible death. CAUTION means light to moderate injury. ATTENTION means property damage. NOTE is a tip. IMPORTANT emphasizes data. These aren’t just stickers – they’re legal statements. The manual says the operator must read and understand the information before operating. If you’re training someone, walk them through page 5 first. Then go into the load charts. The safety section also includes a copyright notice – you cannot photocopy or translate this manual. Respect that.

Why OEM Documentation Matters Here

Aftermarket load charts often combine multiple models into one book. They leave out the specific outrigger settings or use generic tire pressure numbers. This manual is the factory-issued PDF. It matches the decals on the crane. If the police or OSHA asks for your load chart, you hand them the OEM copy, not a printout from a forum. The RT55 is a rough terrain crane – it works on unstable ground. The wrong chart can tip the machine. Trust the factory.

For general background on drivetrain components, the Manual Transmission and Manual Transmission articles give context, but your crane’s specific transmission specs come from the Zoumlion service manual, not here.

Is this manual the same as the operator’s manual?

No, this is a load chart manual only. It must be kept in the cab.

Does it include repair procedures?

This manual covers only load ratings, setup, and safety. For repair or service, you need the separate service manual. The load chart manual is mandatory to keep in the cab per the manufacturer. It includes hoist tackle charts, tire inflation, weights, outrigger float loads, and definitions of load ratings. Do not operate without it.

That load chart is not optional. If you own an RT55, you need this document in your cab and in your file. Access the Factory Manual now and put it where you can reach it – the life depending on it might be yours.
