Link Belt HC-108B Crane Service Pdf Manual
Link-Belt HC-108B Crane Service PDF Manual
The Link-Belt HC-108B is a 45 U.S. ton conventional lattice boom truck crane engineered for heavy lifting operations where durability, serviceability and lifting precision are critical. Featuring Link-Belt's proven HI-LITE angle-type tubular lattice boom, Speed-O-Matic hydraulic controls and a rugged truck carrier, the HC-108B was widely used for steel erection, bridge construction, refinery maintenance and industrial infrastructure projects. This OEM Factory Service PDF Manual contains the original workshop procedures used by factory technicians to diagnose, repair and overhaul the crane's structural, hydraulic, mechanical and electrical systems.
Designed for High-Capacity Crane Rebuilds
The HC-108B was built around modular service principles, allowing technicians to overhaul individual components instead of replacing complete assemblies. From hydraulic counterweight removal and retractable gantries to two-speed planetary hoists and hydraulic live mast systems, this manual follows the same repair sequence used in Link-Belt dealer workshops, making it an indispensable resource for professional crane maintenance.
