Liebherr LTM 1055/1 2001 Technical Manual

I’ve watched guys lift a load using scrap paper numbers scribbled down from the last job. That’s how you fold a boom. This Liebherr LTM 1055/1 2001 Technical Manual is the book that came strapped to the seat – 108 pages of factory load tables, safety protocols, and machine-specific data. No third-party translations, no generic approximations. Liebherr-Werk Ehingen printed this. You want to run this crane right? You start here.

Load Charts: Why OEM Data Matters

Aftermarket load charts might get you close, but close kills. The Liebherr LTM 1055/1 uses a specific radius, boom angle, and outrigger configuration to hit its rated capacity. This manual gives you the exact values from the factory – not a reprint that lost a decimal point. Page 1 even shows the machine identification: manufacturer, type LTM 1055/1, serial number blank for your unit. That attention to detail runs through every page. For guys working on bigger iron, check out Liebherr R 9350 Technical Manual – Specs for Big Iron – same factory pedigree.

Page 1: Product Identification and Safety Disclaimer

First page tells you exactly what you’re holding. Liebherr-Werk Ehingen GmbH, Postfach 1361, D-89582 Ehingen. The model – LTM 1055/1 – and the year 2001. Below that, a warning in bold: ignore these load tables and you risk tipping the crane. That’s not legal padding. That’s real torque on real steel. You don’t guess with 55 tons.

Index Overview – 14 Sections of Operation and Safety

Page 3 gives the full index. Starts with usage instructions for the load charts, then splits into two main operating modes: “su supporto” (on outriggers) and “libera su ruote” (on rubber). Section 5 calls out specific conditions that cause tip-over or overload. Section 6 covers the telescopic boom. Section 7 deals with hoists. Section 10 is the big one – the LICCON overload protection device and limit switches. If you’ve ever had a control unit lock you out mid-lift, you’ll appreciate the factory troubleshooting flow. For a smaller excavator manual with the same detailed structure, see Liebherr R 934 C Technical Manual – Factory Specs for Excavator Repairs.

Does the Manual Cover the LTM 1055/1 Only?

Yes. This is a dedicated technical manual for the LTM 1055/1 model year 2001. It does not lump in other crane variants. The load tables are specific to this machine’s telescopic boom lengths, fly jib configurations, and reeving patterns. If you own a different serial number range, the base data holds – but always confirm against your machine’s data plate. The manual includes a blank for recording your machine number on page 2.

4 Safety Systems You Must Understand

First: LICCON overload protection (Section 10). Second: maximum allowed turret rotation speed (Section 13) – exceed it and control systems cut power. Third: rope reeving diagrams – one wrong wrap and capacity drops 20%. Fourth: the reduction for fly jib attachments (Section 12). The manual explains each system with load reduction percentages, not vague warnings. For the drivetrain, the crane uses a manual transmission – understanding gear ratios matters when traveling under load. See Manual Transmission for fundamentals, then cross-reference with this manual’s travel mode instructions. Another good external resource on manual transmission basics is Manual Transmission, especially if you’re rebuilding the crane’s powertrain.

Audience: Who Benefits from This Factory Data?

Crane operators will use this daily on site. Mechanics repairing the boom or hoist need the correct reeving sequences from Section 11. Owners validating rental fleet load charts need the original specs. DIY heavy-equipment guys who bought a used LTM 1055/1 – you cannot guess the capacities. One wrong lift and you’re buying a new boom. This 108-page book keeps you honest. If you work on crawlers, take a look at Liebherr R 956 2013 Technical Manual – Factory Specs for Crawler Excavator for the same level of factory detail.

Source Validity: Factory Print, Not a Copy

This is a direct scan of the original 2001 Liebherr publication – not an aftermarket re-typeset. The Italian language version (original file identified as LIEBHERR_LTM_1055-1_2001_Technical_Manual_it-37813005905.pdf) matches the German master reference. Every table, every footnote, every warning. I’ve seen shops run on photocopies that skip the fine-print hazard notes. Not here. You get the full .pdf, readable on any device.

What exactly is included in this 108-page manual?

The complete load chart book – maximum load tables for all boom configurations, outrigger positions, and travel modes. Safety warnings, LICCON system details, reeving diagrams, and symbol definitions.

Is the manual in English?

This specific copy is in Italian, but the load tables use numbers and symbols that are language-independent. The safety text is Italian; if you need English, check the model-specific English edition on our site.

Does it cover repair procedures or just load charts?

This is a load chart technical manual, not a service repair manual. It focuses on safe operation and capacity limits. For engine or hydraulic repairs, you need the separate service manual.

Can I print this manual for shop use?

Yes. The PDF is not locked. Print selected pages for the cab, or keep the full manual on a tablet. We recommend laminating the main load table page for daily reference.

If you run an LTM 1055/1, you need the data that built the crane. Stop trusting second-hand numbers. Access the Factory Manual from AutoRepairManuals and keep the original specs in your hands.
