Liebherr LTM 1060-1 2000 Electrical Schematic – 110 Pages Factory Wiring

Description

Look, I’ve seen too many cranes deadlined because some shop bought a third-party wiring diagram that didn’t match the actual harness. This Liebherr LTM 1060-1 2000 Electrical Schematic is the real deal – scanned from the original German factory prints. 110 pages of circuits, connections, and control logic that Liebherr engineers designed. No aftermarket re-draw. No guessing.

Page 1 shows the SCHALTPLAN DREHBÜHNE (slewing platform wiring) with Liebherr’s own drawing number 3335-932.08.00.001-000 and their copyright stamp. That tells you this came straight from the Werk Ehingen. The BLATTVERZEICHNIS on page 2 lists every sheet from voltage supply to the KLEMMEN-PLAN terminal diagrams. You want to trace a LICCON incremental encoder for winch 1? It’s on page 25. Need the pressure sensor wiring? Page 27.

Liebherr LTM 1060-1 2000 Electrical Schematic: Factory Wiring, Not a Copy

Every one of those 110 pages carries the original Liebherr part number and revision history. The sheet index (Blattverzeichnis) runs from ZENTRALEINHEIT 0 through GERÄTEÜBERSICHT. That includes Spannungsversorgung (voltage supply) for both Oberwagen and Unterwagen, Massführung (ground paths), and Steckerbelegung (pin assignments). If you’re tracing a short in the hubwerk control or need to verify the pumpensteuerung relay logic, this schematic gives you the exact wire colors and connector pin numbers used at the factory.

Voltage Supply and Ground Paths – Pages 8 to 13

Power distribution is the first thing I check on any machine. Pages 8 through 11 cover the voltage supply for the upper and lower carriages. Pages 12 and 13 map every ground connection – critical for avoiding phantom loads that drive techs crazy. The schematic shows the Masse – Verbindungen (ground connections) in detail, including the tie points for the LICCON system and the main control unit. Don’t skip these pages when diagnosing intermittent failures.

LICCON Control System: Monitor, Fans, and Encoders

The LICCON module runs the crane’s central logic. Pages 21 to 26 cover its power supply, monitor, cooling fan, and the incremental encoders for winches 1 and 2. Page 24 shows the Lüfter LICCON (fan circuit) – a common failure point that can cause overheating. And page 23 gives you the monitor pinout. Combined with the Steckerbelegung pages 88–90, you can bench-test the entire controller board without the crane present.

Pin Assignments and Connector Views – Pages 88–90

Three full pages of Steckerbelegung – connector pin assignments for the main harness. Each page lists the plug number, cavity location, wire color, and destination. This is what you need when you’re repinning a damaged connector or building an adapter cable for a diagnostic tool. The same style continues through pages 91–92 with Geräteübersicht (component overview) – every relay, solenoid, and sensor location.

Emergency Operation and Safety Circuits – Page 69

Page 69 (Notbetrieb) is the one you hope you never need but absolutely must have. It shows the emergency override circuits, including safety chain feedback (page 54) and the master switch releases (page 20). If the crane’s display goes dark and you need to manually retract outriggers, these diagrams are your only reliable source. Do not trust aftermarket copies that omit these safety interlocks.

For reference, the Liebherr R9800 2012 Electrical Schematic – OEM Water System Chapter”>Liebherr R9800 2012 Electrical Schematic covers a larger excavator’s water system, but this LTM manual is specific to the telescopic crane. Need a different model? The Liebherr R934B 2004 Electrical Schematic – Factory Wiring Guide”>Liebherr R934B 2004 Electrical Schematic covers a medium excavator, and the Liebherr LTM 1040-2.1 2006 Electrical Schematic – Section: Voltage Supply Est-37″>LTM 1040-2.1 2006 Electrical Schematic shares similar voltage supply architecture.

If you want to understand basic automotive wiring theory, the Automotive Wiring”>Automotive Wiring guide covers fundamentals. For industry context on heavy equipment safety standards, see the Automotive Industry Overview on Wikipedia.

Can I use this manual to troubleshoot the crane’s electrical system?

Absolutely. This is the exact schematic used by Liebherr technicians. It includes full wiring for the LICCON controller, voltage supply, ground paths, connector pinouts, and safety circuits like the Notbetrieb (emergency operation) on page 69. Many shops I know have printed these pages and laminated them for the cab. You can trace any circuit from sensor to actuator using the sheet references and wire color codes. Just keep in mind the German labels – but the numbers and symbols are universal.

Is this manual in English?

No, it’s in German. The diagrams themselves are standard symbols, so language is not a barrier.

Does this include the engine wiring?

Pages 15 and 16 cover “Motor Fahrzeug” – the vehicle engine. You get the starter, alternator, and ECU connections. If you need the Deutz or Mercedes-specific engine harness, this is your page.

What format is the PDF?

It’s a scanned PDF of the original 110-page schematic at 300 DPI. Every drawing is clear and zoomable. Works on a tablet in the shop or printed 11×17.

Access the Factory Manual and keep a copy in your service truck. When a customer asks why their LTM 1060-1 won’t extend the boom, you’ll have the answer within thirty seconds.
