The Liebherr MK 140 Mobile Construction Crane spends its life on tight sites, doing fast setup and teardown where downtime really hurts. When something electrical or hydraulic acts up, the first guy reaching for a BMK is usually the tech trying to match a fault or schematic symbol to a real-world box, plug, or valve. Component identification is what keeps you from tearing half the crane apart just to find one relay or sensor buried in the superstructure. This Technical Information & BMK Components Manual for SN 077511 is built exactly for that job, not for step‑by‑step repairs.
What this manual helps you do
- Identify where specific components sit on the MK 140 carrier and superstructure using outline and layout diagrams.
- Locate items like “K15” or “X45” on the actual crane when you only have the reference from a wiring or hydraulic schematic.
- Trace harnesses and component groups visually so you know which panels, covers, or walkways to open before you start work.
- Cross-reference Liebherr component IDs to other factory documents like wiring diagrams or technical fault info.
- Pinpoint what Liebherr calls a given sensor, relay, valve, or connector so you can talk the same language as the parts desk or service rep.
Who this is for
This is aimed at workshop technicians, field service techs, electrical diagnostic engineers, fleet mechanics, and training instructors who need clear component locations. If you’re after repair procedures, torque specs, or part numbers, you actually want a service manual or a parts catalogue instead.
FAQ
Q: Are the diagrams clear and searchable in PDF form?
A: These BMK PDFs are usually clean scans or originals with legible component callouts and can be searched by text where the source allows.
Q: Does it cover both the carrier and the upper crane body?
A: Yes, this BMK combines carrier and superstructure component identification for the MK 140 into one product.
Q: Does it tie in with other Liebherr manuals I already have?
A: Yes, the BMK is meant to be used alongside wiring diagrams, hydraulic schematics, service manuals, and parts catalogues by matching the reference designators.
Bottom line: If your main need is “Where exactly is this component on my Liebherr MK 140, and what does Liebherr call it?”, this is the right manual. If you need how‑to repair steps or part numbers, this isn’t it.
