Link-Belt HC-138 Crane Service PDF Manual
The Link-Belt HC-138 is a 65 U.S. ton conventional lattice boom truck crane designed for demanding lifting applications where reliability, long reach and dependable field service are essential. Built on a heavy-duty multi-axle carrier with hydraulic outriggers and a powerful revolving upper, the HC-138 became a popular choice for bridge construction, refinery shutdowns, power projects and steel erection. This OEM Factory Service PDF Manual provides the original workshop procedures used by Link-Belt technicians to inspect, troubleshoot, repair and completely overhaul the crane's carrier, upper structure, hydraulic systems and mechanical drive components.
Comprehensive Coverage from Carrier to Boom Machinery
Unlike basic repair guides, this factory manual covers both the rubber-tire carrier and the revolving crane assembly in one reference. It includes detailed service procedures for steering, air brakes, hydraulic outriggers, planetary drum drives, boom hoist mechanisms and the complete Speed-O-Matic hydraulic power supply, allowing technicians to perform accurate repairs while maintaining original factory performance.
