Liebherr LTM 1130-5.1 Technical Manual

Listen, if you’re working on a construction crane that cost more than your house, you don’t guess. You pull the factory manual. The Liebherr LTM 1130-5.1 Technical Manual is 71 pages of exactly what Liebherr wanted you to know – nothing more, nothing less. I’ve torqued enough head bolts to know that one wrong spec on a hydraulic pressure sensor can turn a job into a rework. This document gives you the OEM torque values, wiring pinouts, and emergency override procedures that aftermarket reprints screw up.

Liebherr LTM 1130-5.1 Technical Manual – Control Cabinet and LICCON System

That control cabinet section alone makes this manual worth the price. You get the swing frame fuses, relay locations, input circuit boards, CPUs, and the full CAN and LSB station layout with voltage transformer diagrams. If you ever need to run emergency operation without the LICCON system – and trust me, on a job site you might – pages 21-23 walk you through the operation, the X-Not plug, and the resistor values. Don’t try to reverse-engineer that from a generic schematic. You’ll toast a board. Liebherr LTM 1130-5.1 Technical Manual is the only way to get it right.

Does This Manual Cover the D 934 S TI A6 Diesel Engine?

Yes, and it covers it better than any aftermarket publication. From page 24 onward you get the right side view, left side view, top view, and frontal view of the engine – all with part numbers for the slip-on pumps, oil pressure and fuel temperature sensor (page 26 – that’s your torque spec location), fuel preliminary filter unit, speed sensor, installation view, air filter vacuum, cooler/fan drive, charge air pressure and charge air temperature sensor, coolant level and temperature sensor, air flap optional, and the LH ECU UP/CR engine control unit. Unlike a Manual Transmission where you can fudge clearances, this engine demands factory spec on every sensor bolt.

3 Critical Sections for Crane Hydraulics Repair

First: the overview of hydraulic components and pumps – you need to know which pump feeds which circuit before you start pulling lines. Second: the main control block, with and without hoist gear 2, plus the pressure stage valves. Third: the emergency operation LMB bypass (EN13000 from crane number 065936). The manual includes hoist gear I and II, luffing/telescoping, temperature sensor, and the swing drive with brake and angle indicator. If you’re diagnosing a dead hoist or a stuck slewing brake, this is the chapter you open first. For bigger iron, check out Liebherr R 9350 Technical Manual – Specs for Big Iron – but for the LTM 1130-5.1, this is the exact document.

Get the Right Torque Data from Page 26

Page 26 is where you’ll find the oil pressure and fuel temperature sensor specs. That page also includes the sensor location and connector pinout. I’ve seen guys on forums argue about whether that sensor takes 18 or 22 Nm. The factory manual settles it. No guessing, no cross-referencing a third-party spreadsheet. You turn the page, you see the number, you set your torque wrench. Same applies to the charge air pressure sensor – it’s all there. Liebherr R 934 C Technical Manual – Factory Specs for Excavator Repairs is another solid reference for excavator work, but for this crane, stick with the OEM LTM manual.

Source Validity: Why OEM Beats Aftermarket

This PDF is a direct scan of Liebherr’s own Kundendienst-Technische Dokumentation – their service technical documentation. It includes both German and English sections, with the full index and BMK (Betriebsmittel Kennzeichnung) component tags. No reprints, no generic diagrams, no third-party editor deciding what to leave out. The original file name ends in 37813017210 – that’s a Liebherr part number. You get the exact same book the dealer techs use. For external context on how component tagging works in heavy equipment, you can look up Manual Transmission designations – but that’s not a substitute for this manual.

Is this manual in English?

Yes, the manual includes both German and English sections – the English part starts after the German index.

Can I use this manual for crane serial numbers below 065900?

The manual is specified for LTM 1130-5.1 from crane number 065900 onward. If your crane is older, some components may differ. You should verify your crane’s serial number before relying on the hydraulic pressure stage valve diagrams or the LICCON emergency operation procedures. The engine section applies to the D 934 S TI A6 regardless, but the superstructure wiring may vary. Always cross-check the serial number against the BMK component tags in the manual to confirm compatibility.

Stop trying to interpolate specs from a Chilton. Get the real document. Access the Factory Manual from AutoRepairManuals and put it on your tablet. You’ll have the right torque values, the right wiring colors, and the emergency procedures that could save you a call to the dealer.
