Description

Liebherr LTM 1090-4.1 Spare Parts Catalogue PDF

The Liebherr LTM 1090-4.1 Spare Parts Catalogue PDF is a detailed illustrated parts reference for the LTM 1090-4.1 mobile crane. The catalogue is arranged around assembly drawings and corresponding item lists so components can be identified by position, article number, quantity and description. Its introductory guidance explains that the catalogue is intended to support spare-parts identification and ordering in connection with maintenance or repair, with picture pages leading into detailed part listings for the relevant assemblies.

With 1,291 pages, this LTM 1090-4.1 parts catalogue covers the crane from the undercarriage and driving equipment through steering, suspension, stabilizers, cabins, electrical and pneumatic equipment, superstructure, slewing components, hoisting equipment, telescopic boom, folding jib and associated accessories. The document also contains many assembly drawings, hydraulic layouts and component views that help establish where a listed part belongs within the larger system.

Illustrated Parts Identification

The catalogue uses numbered illustrations together with structured parts lists. The opening remarks explain how picture and text pages are organized and how arrows in the contents lead to detailed plate and item information. This makes the Liebherr LTM 1090-4.1 parts book particularly useful when a component has to be traced from its installed position to the corresponding article number. Numerous assemblies are broken down into individual components, fasteners, hoses, fittings, valves, sensors, brackets, seals and related hardware.

Examples of the level of detail include the diesel engine installation and pre-assembled engine, where the D846 A7 diesel engine is identified alongside the 12AS2302 switchgear, clutch assembly and pump assembly. The running gear sections break out individual axles, suspension cylinders, steering cylinders, axle struts and hydraulic items. Separate illustrated sections cover the mechanical steering system and steering hydraulics, while the stabilizer area includes front and rear sliding beams, extension rams, strut cylinders and support-plate assemblies.

The same parts-oriented structure continues into the crane superstructure. The catalogue identifies slewing components, luffing equipment, hoisting assemblies, hydraulic and electrical systems, the crane operator’s cabin, control stand, counterweight equipment, telescopic boom assemblies and folding-jib equipment. This broad coverage allows the Liebherr LTM 1090-4.1 Spare Parts Catalogue PDF to serve as a single reference for a wide range of component-identification tasks across the machine.

Taken together, these sections provide a component-by-component map of the LTM 1090-4.1. The combination of assembly plates and parts lists is useful when comparing an installed component with the illustrated assembly, confirming the relevant item position, or tracing related pieces within the same system. Because the catalogue spans both the carrier and crane superstructure, it can be consulted for mechanical, hydraulic, pneumatic, electrical, cabin, boom and lifting-equipment parts rather than being limited to a single subsystem.

Detailed Assemblies Across the Crane

For technicians working on the carrier, the parts catalogue goes beyond basic chassis items. It includes detailed axle assemblies with steering and suspension components, mechanical and hydraulic steering sections, drive-shaft fittings, tyre and wheel information, cooling equipment, fuel and oil installations, air vessels and compressed-air equipment. The stabilizer/sliding-beam sections show the structural beams and their extension and support components, giving a clear parts breakdown for assemblies that are often difficult to identify from the outside of the crane.

In the cab area, the catalogue provides illustrated breakdowns for the driver’s cabin, glazing-related structures, doors, mirrors, seats, steering column, wiper system, instrument box and associated fittings. Electrical items are distributed through dedicated system sections for the undercarriage, driver cabin, lighting, control equipment and crane systems. This organization is valuable when an electrical or cab component needs to be matched to the correct mounting arrangement or surrounding parts.

On the superstructure, separate sections document the slewing platform, slewing ring and gear, luffing equipment, counterweight arrangements, hydraulic equipment, oil cooling, superstructure hose and pipe routing, electrical systems and crane-operator controls. The boom section includes the complete telescopic unit and individual telescopic sections, together with boom electrical and hydraulic equipment. Folding-jib and hook-related sections extend the coverage into lifting accessories and optional assemblies represented in the catalogue.

Part Numbers, Positions and Assembly Context

Each illustrated plate is tied to a parts list containing the corresponding item positions and article numbers. That relationship is the core value of this Liebherr LTM 1090-4.1 spare parts reference: it helps move from a visual location on the crane to a specific listed component and then to related pieces in the same assembly. Lists include quantities and descriptions where provided, and many entries lead to deeper subassemblies. This can be especially helpful when a complete assembly contains smaller serviceable or replaceable elements such as seals, retaining rings, brackets, fittings, hoses, valves or sensors.

The catalogue’s own ordering guidance also stresses checking the crane type and works number and using the correct picture/text page information when identifying a required spare part. That is important for a machine with numerous related assemblies and configuration-dependent components. Before ordering, the identified article number should therefore be checked against the particular crane and the relevant catalogue plate.

Get the Correct Parts Reference for Your LTM 1090-4.1

The Liebherr LTM 1090-4.1 Spare Parts Catalogue PDF gives owners, workshops and crane technicians a practical reference for identifying components throughout the carrier, steering and suspension systems, stabilizers, cabins, electrical and pneumatic equipment, superstructure, slewing system, hoists, telescopic boom and folding jib. Having the correct assembly drawings and article-number listings at hand can reduce guesswork when planning maintenance or repair, checking which components belong together, and preparing a parts order.

Correct part identification matters on a complex mobile crane because visually similar components can belong to different assemblies or positions. This catalogue provides the illustrated context, item numbers and part descriptions needed to work methodically from the machine to the relevant parts listing. Delivery is instant as a PDF after purchase, with no physical shipping required. The file can be kept on a phone, tablet, laptop or desktop computer for workshop and field reference, and pages can be printed whenever a paper copy is more convenient.
