Each of these assemblies is further broken down into individual components with item numbers, quantities, descriptions in both German and English, and references to subordinate parts where applicable. The catalogue also includes a numerical index sorted by item number and an alphabetical index sorted by item designation, making it easy to locate a specific part regardless of whether you know its function or its part number.

Additionally, the catalogue contains dedicated hose lists for the various hydraulic circuits, allowing you to identify and order hydraulic hoses by their hose number. This is particularly valuable for maintenance planning and for replacing damaged hoses with the correct specification.

Why This Parts Catalogue Is Essential

The Liebherr LHM 420 is a highly complex mobile harbour crane with thousands of individually numbered components. Many parts are similar in appearance but differ in material, dimensions, or pressure rating — and using the wrong part can lead to equipment damage, safety hazards, and costly downtime. This catalogue eliminates that risk by providing the exact Liebherr item number for every component on the machine.

Because this catalogue is specific to serial number 141737, it accounts for the exact configuration of that machine, including any factory-fitted options and modifications recorded up to the publication date. This level of specificity is critical: a generic parts catalogue may list components that do not match your machine’s build, leading to incorrect orders and delays.

The bilingual German/English format makes the catalogue usable across language barriers. Whether you are working with a German-speaking Liebherr parts desk or an English-speaking aftermarket supplier, you can quote the exact item number and description with confidence. The item numbers follow Liebherr’s standard numbering system, ensuring compatibility with Liebherr’s parts ordering systems worldwide.

What You Can Do With This Catalogue

• Identify the correct replacement part for any component on the LHM 420 — from structural pins and bushings to hydraulic pumps, valves, and electronic modules
• Order spare parts with confidence using exact item numbers and quantities
• Plan maintenance and repairs by reviewing the complete parts breakdown for each assembly
• Cross-reference part numbers between the German and English descriptions
• Locate hydraulic hoses using the dedicated hose lists and hose numbers
• Verify the configuration of your machine against the catalogue’s serial number range
• Prepare accurate parts lists for major overhauls or rebuilds
• Reduce downtime by having the correct part number ready before contacting your supplier
