Zoomlion RT75 2013 Technical Manual – The Load Chart Bible

If you’re running a Zoomlion RT75 2013 Technical Manual job, the one thing that will stop you cold is guessing the load rating. This 49-page factory document is the difference between a crane that works and a crane that folds. I’ve spent 28 years turning wrenches, and I’ve seen guys kill a crane (and nearly themselves) because they used a photocopied chart from 2008. This is not that. This is the OEM print from Zoomlion, dated December 2013, Edition 1, part number 0075611-002. No aftermarket translation, no missing pages.

Load Ratings: The Only Numbers You Trust

This manual is built around five sections of load charts, each tied to a specific outrigger configuration. The table of contents spells it out: Main Boom Rated Loads with all outriggers fully extended, pinned mid-position, less than half extended, and then a standalone main boom section. Every chart gives you the maximum allowable load for a given boom length, radius, and angle. The factory even includes the Hoist Tackle Chart, the Tire Inflation Chart, and a Weights table. If you’re trying to figure out what your RT75 can pick at 10 meters with a 33-foot jib, that data is on the page labeled 10 M (33 ft) JIB RATED LOADS. No guesswork—just raw, approved numbers.

Setup Procedures: Get the Outriggers Right

Under every load chart section, the manual splits into Set-up and Operation sub-headings. The set-up instructions for the fully-extended outrigger position are not the same as the mid-position. Most accidents happen because someone uses the wrong chart for their outrigger stance. The manual forces you to check: are your outriggers pinned at the mid-position? Then flip to section 0075611_002_03_23.2Y. Less than half extended? That’s section 0075611_002_04. Each one has its own Set-up procedure that tells you exactly what the stabilizers must look like before you lift a pound. I’ve torqued more bolts than I can count, but crane safety is about geometry and weight, not torque. This manual locks that down.

Why Factory OEM Beats Aftermarket Copies

Zoomlion prints these manuals for one reason: to keep the operator alive and the crane legal. Aftermarket copies frequently cut the Safety section (page 5 in this one) that explains hazard indicators—DANGER, WARNING, CAUTION, ATTENTION, NOTE, and IMPORTANT. That page is not decoration. It tells you the difference between a warning that can kill you and a note that saves you a headache. An aftermarket scan might also drop the copyright page, meaning you’re holding an illegal copy. This listing is the genuine factory file, 49 pages, no reprints, no third-party edits.

Who Needs This Manual?

If you operate, maintain, or rent an RT75 rough terrain crane, this is the load chart reference you keep in the cab. The factory says, “The operator must keep this manual in the cab of the crane.” That’s the rule. A shop mechanic like me who has to verify that the crane is set up correctly for a lift—this manual is how you check. The Tire Inflation Chart alone prevents you from running a tire under-inflated, which changes the load rating on rubber. Beginners should not touch a crane without reading the GENERAL and DEFINITIONS sections first. Those pages explain terms like “rated loads” and “operating radius” in plain language (translated from Chinese, but clean).

Real-World Data You Can Act On

Need the charge pressure? Not in this manual—this is load charts only. But if you need the Main Boom Rated Loads for a 10-meter radius with a 33-foot jib, the table shows you the exact kilogram limit. The manual covers two jib lengths: 10 m (33 ft) and 17 m (56 ft). Each jib section has its own Set-up and Operation sub-sections. The factory also lists Hoist Tackle configurations—single line, multi-part—with weight limits per line. If you’re swapping from a hook to a headache ball, this chart tells you the maximum load per line.

Can’t Afford to Guess the Limits

A crane lift is not a 50-50 bet. The RT75 2013 manual from Zoomlion gives you the certified numbers. Pair it with the ZOOMLION RT75 Rough Terrain Crane Operator’s Manual for full operating instructions, or the ZOUMLION RT75 Rough Terrain Crane Spare Parts Catalog if you need replacement parts. For the transmission and drivetrain fundamentals, a quick refresher on Manual Transmission operation can help you understand the crane’s power flow. But the load charts are the core. The Manual Transmission knowledge is secondary—load limits come first.

FAQ

Does this manual include repair procedures for the engine or hydraulics?

No. This is a load chart manual only—no engine timing specs, no hydraulic schematics, no bolt torque tables.

What load charts are covered for the outrigger positions?

Five full sections: main boom with outriggers fully extended, main boom with outriggers pinned in the mid-position, main boom with outriggers less than half extended, plus a separate main boom section and two jib rated load tables (10 m and 17 m). Each section has setup and operation instructions specific to that outrigger configuration. The manual also includes a hoist tackle chart, tire inflation chart, and general definitions. That’s 49 pages of strictly load-related data—nothing else.
