Liebherr 维修手册

The Liebherr Group was founded in 1949 by Hans Liebherr in Kirchdorf an der Iller, Germany, after he developed an affordable mobile tower crane for the postwar building boom. The company grew into a family-owned group of more than one hundred companies spanning earthmoving machinery, mobile and tower cranes, mining trucks, maritime cranes, components and household appliances.

Liebherr is known for engineering machines to exacting standards, including a range of in-house diesel engines designed for long service life in demanding duty. Its excavators, crawler tractors, wheel loaders and mining trucks are mainstays on construction sites and in quarries, and the group's D-series engines are respected for their strength and straightforward service access. The D 9306, D 9308, D 9406 and D 9408 models featured in the listings are typical of the group's in-house diesel program.

Workshop manuals for Liebherr cover the engine and machine systems in factory detail: mechanical overhaul, fuel injection and emission equipment, cooling and lubrication, hydraulic systems, electrical circuits with wiring diagrams, torque specifications and diagnostic procedures. Scheduled maintenance data supports safe, economical operation over the life of the machine. Hydraulic and electrical chapters are as detailed as the engine work, reflecting the integrated machines Liebherr builds.

These documents are written for equipment owners, contractor maintenance departments, independent heavy-equipment technicians and operators of older Liebherr machines. Factory specifications help maximize uptime and protect the value of substantial capital equipment.
