The Liebherr LTM 1110-5.2 Mobile Crane earns its keep on sites where setup space is tight and you still need serious reach and capacity. When something acts up, the first people reaching for a BMK / component identification manual are usually the electrical and hydraulic guys trying to match a fault or symbol to a real part on the machine. In a workshop, knowing exactly where Liebherr put “K15” or “V12” saves a lot of wasted time and wrong guesses. This Technical Information and BMK Components Manual for SN 091838 is built for that kind of work, not for how-to repairs.
What this manual helps you do
- Identify which physical component matches a reference like E1, K3, or X45 in your wiring or hydraulic diagrams.
- Locate the exact mounting position of sensors, valves, relays, and control units on the carrier and superstructure.
- Trace harness routes and component groups using outline and layout views of the crane.
- Cross-reference Liebherr’s internal component IDs with items mentioned in service information or fault code readouts.
- Pinpoint components on visual overlays so new techs learn the machine layout faster and stop hunting blindly.
Who this is for
This is aimed at workshop technicians, field service techs, electrical diagnostic engineers, fleet mechanics, and training instructors who already have or plan to use wiring diagrams and service info. If you mainly need repair procedures, torque specs, or part numbers, you want the service manual and parts catalogue instead, not this BMK.
FAQ
Q: Is the PDF clear and searchable enough to use on a laptop in the shop?
A: Yes, these BMK PDFs are normally scanned or generated so diagrams are readable and text can be searched by component ID.
Q: Does it cover both the carrier and the superstructure layouts?
A: Yes, this Technical Information & BMK Components Manual covers component identification for both carrier and superstructure on this crane.
Q: Does it work together with Liebherr wiring diagrams and parts catalogues?
A: Yes, the BMK is meant to sit beside those; you match the reference designator in the diagram to the BMK, then go to the parts or service info once you’ve found the part.
Bottom line: If your main question is “Where is this component on my Liebherr LTM 1110-5.2?” this is exactly the right manual. If your main question is “How do I fix or order it?” this is not the one you need.
