Zoumlion RT35 2013 Technical Manual – Load Chart and Spec Data

Every time you move a load with a rough terrain crane, the difference between a safe lift and a wrecked machine comes down to one piece of paper: the load chart. If you’ve been working with photocopied, faded, or translated charts, you’re gambling. I’ve seen it. The Zoumlion RT35 2013 Technical Manual is the factory load chart manual for the RT35 Rough Terrain Crane. It’s 53 pages of original OEM data, printed in 2013, and meant to sit in the cab – not your glove box.

This manual comes straight from Zoomlion Heavy Industry Science and Technology Co., Ltd. You get the same load ratings, boom charts, and hazard indicators the factory put in the crane when it shipped. No aftermarket reprints. No editorializing. Just the numbers that keep you from tipping over.

Load Ratings and Boom Configurations

Page 2 of this manual carries the official load ratings for the RT35. These are the numbers that tell you exactly how much weight you can pick at every boom length, angle, and radius. The chart accounts for outrigger extension, counterweight, and whether you’re on rubber or outriggers. If you’ve ever tried to guess a lift based on a faded sticker or a table from a different model, you know how fast that can go wrong. This manual removes the guesswork completely.

What Load Ratings Are Listed in the RT35 Manual?

The load rating tables cover all standard operating configurations. You’ll find capacities for on-outrigger lifts, on-rubber lifts, and travel positions. Each table is broken down by boom length and working radius. The manual also includes notes about stability limits – don’t ignore those. A crane’s capacity is rarely limited by structural strength; it’s almost always stability. That’s why the factory spends so much effort printing the exact values. And if you need the parts breakdown or service procedures, pair this with the ZOUMLION RT35 Rough Terrain Crane Parts Catalog for a complete workshop setup.

53 Pages of Factory Data

The manual is 53 pages long. That may sound thin compared to a service manual, but every page is dense with specific information. Hazard indicators – DANGER, WARNING, CAUTION – take up pages 4 and 5, because the manufacturer knows that one wrong move with a crane kills people. The load rating section spans the core of the document. There’s also a section on how to read the charts and what the symbols mean. This is not a general guide; it’s the exact manual that shipped with the RT35 in December 2013. The copyright page explicitly forbids copying or electronic reproduction – that’s how tightly the factory controls its data.

Understand the Hazard Indicators Before You Operate

Page 5 of the manual shows the standard hazard markers: DANGER for death or injury, WARNING for possible death or injury, CAUTION for minor injury, and ATTENTION for property damage. The manual insists that the operator read and understand these before running the crane. Every time I see a new guy hop into a crane without reviewing the manual, I stop him. The load chart is worthless if you don’t know the warning conventions. Treat those symbols like you treat a 10-mm socket – you better know where they are and what they mean.

Load Chart Manual: Why OEM Matters

Aftermarket load chart compilations are a danger. I’ve seen tables misaligned, outrigger positions swapped, and capacity numbers rounded off. The OEM Zoomlion manual carries the exact values the factory engineers calculated. The difference between a 36,000 lb capacity and a 36,500 lb capacity might not look like much on paper, but if your load is 36,200 lb, that 500 lb error can send you onto your side. Stick with the factory source. If you operate other Zoomlion models, check the ZOUMLION RT55 Rough Terrain Crane Load Chart Manual and Zoomlion RT100 Rough Terrain Crane Load Chart Manual for consistent data across the fleet.

One more thing: this manual is a load chart manual, not a repair manual. If you need engine overhaul procedures or torque specs for the transmission, you’ll need a different document – the difference between a load chart and a Manual Transmission repair guide is the type of data. Both are critical, but don’t expect to find valve adjustment specs here.

For comparison, a Manual Transmission rebuild requires very different information. The point is: use the right manual for the job. This one is for lifting, not fixing.

Frequently Asked Questions

Is this manual for the Zoumlion RT35 or Zoomlion?

It’s the same. The product name uses Zoumlion, but the manual cover says Zoomlion. The data is identical.

Does this manual include engine repair procedures?

No. This is a load chart manual only. It covers lift capacities, boom configurations, and safety warnings. For engine or transmission work, you need the service manual.

Can I use this load chart for crane models other than the RT35?

Never. Each model has its own load chart based on its specific structural limits, outrigger span, and counterweight. Using an RT35 chart on an RT55 could kill you.

Where should I keep this manual?

The manufacturer requires the manual to stay in the cab of the crane at all times. If you sell or transfer the crane, the manual goes with it. The original operator’s manual from Zoomlion states that if the crane becomes the property of a different person, the manual must remain in the cab. That’s not a suggestion – it’s a legal and safety requirement. Without the load chart, the next operator has nothing to reference when planning lifts. I’ve seen a crane roll over because the chart was missing. Keep it in the cab, in a sealed pouch, readable. If it gets destroyed, get a replacement immediately.
