Link Belt HC-238B Crane Service Pdf Manual
Link-Belt HC-238B Crane Service PDF Manual
The Link-Belt HC-238B is a 140 U.S. ton conventional lattice boom truck crane developed for high-capacity lifting operations where strength, precision and long-term reliability are critical. Equipped with a heavy-duty four-axle carrier, tubular boom, hydraulic outriggers and advanced hoisting systems, the HC-238B has been widely used on bridge construction, refinery shutdowns, power generation facilities and large steel erection projects. This OEM Factory Service PDF Manual provides the original workshop procedures required to diagnose, disassemble, inspect, repair and rebuild the crane using factory-approved service methods.
Designed for Professional Crane Rebuilds
The HC-238B was engineered with serviceability in mind, allowing major mechanical and hydraulic assemblies to be restored instead of replaced. This factory manual follows the same repair sequence used by authorized Link-Belt service technicians, covering everything from carrier steering and air brake diagnostics to hydraulic power supply troubleshooting, swing brake adjustments and live mast cylinder repairs. It is an essential workshop reference for maximizing crane uptime and extending component life.
