Link Belt 138 HYLAB 5 Crane Service Pdf Manual
Link-Belt 138 HYLAB 5 Crane Service PDF Manual
The Link-Belt 138 HYLAB 5 is an 80-ton lattice boom crawler crane developed for contractors handling bridge construction, deep foundation work, structural steel erection and heavy industrial lifting. Designed with a durable crawler undercarriage, powerful hoist system and modular lattice boom, the 138 HYLAB 5 delivers dependable lifting performance in demanding environments where stability is critical. This OEM Factory Service PDF Manual provides professional repair procedures, complete disassembly instructions and diagnostic information to restore every major component to factory operating standards.
Built for High-Duty Cycle Construction Projects
Unlike modern telescopic rough terrain cranes, the 138 HYLAB 5 is engineered around a conventional crawler design that excels on long-duration lifting operations. Its lattice boom configuration, heavy-duty drum assemblies, crawler travel drives and mechanical power transmission make it an excellent choice for piling operations, bridge girders, precast concrete placement and refinery construction. The crane's serviceability allows major components to be rebuilt rather than replaced, making factory repair procedures especially valuable.
