The Liebherr LTM 1070-4.1 is a road-going mobile crane that spends its life shuttling between jobsites, where downtime is expensive and access is tight. When something electrical or hydraulic acts up, the first person reaching for the BMK is usually the tech with a multimeter in one hand and a laptop or tablet in the other. Component identification matters because if you can’t quickly match “K15” or “V23” from a diagram to the real hardware on the crane, you waste hours just finding the right box, valve, or plug. The Technical Information & BMK Components Manual for Liebherr LTM 1070-4.1 Mobile Crane is built exactly for that locating-and-matching job, not for step‑by‑step repairs.
What this manual helps you do
- Identify which physical component matches a schematic tag like E1, K3, or X45 on this specific crane (SN 059439).
- Locate sensors, valves, relays, and connectors on the carrier and superstructure using outline and layout diagrams.
- Trace wiring or hydraulic references from other Liebherr diagrams to their actual mounting points on the machine.
- Cross-reference Liebherr component IDs with the terms used in service manuals, fault code lists, or training material.
- Pinpoint what a “mystery box” or connector is called in Liebherr’s own nomenclature so you can talk to support or parts.
Who this is for
This BMK/component identification manual is aimed at workshop technicians, field service techs, electrical diagnostic engineers, fleet mechanics, and training instructors. If you need repair procedures, torque specs, or part numbers, you want a service manual and a parts catalogue instead.
FAQ
Q: Are the diagrams clear and is the PDF searchable?
A: You can expect clear outline drawings and labeled component views; most shops use these comfortably on a laptop or tablet as a searchable PDF.
Q: Does it cover just the upper crane or the whole machine?
A: This product covers both carrier and superstructure BMK content together for the LTM 1070-4.1, tied to serial number 059439.
Q: Does it tie in with other Liebherr manuals I already have?
A: Yes, these component IDs are what you match against wiring diagrams, hydraulic schematics, service manuals, and parts catalogues.
Bottom line: If your main need is to find and identify components on a Liebherr LTM 1070-4.1 in the field or workshop, this is the right manual. If you’re after how to fix or replace them, it’s not.
