Link-Belt 120RT XP Crane Service PDF Manual
Built for demanding heavy-lift projects, the Link-Belt 120RT XP combines high-capacity lifting with advanced electronic controls and excellent rough-terrain mobility. Designed around a 120 US ton (110 metric ton) lifting platform, this crane features a six-section greaseless pin-and-latch telescopic boom, Pulse 2.0 operating system, V-CALC variable outrigger monitoring and a heavy-duty four-wheel drive carrier. Whether working on wind turbine erection, refinery maintenance, bridge construction or large industrial installations, this OEM Factory Service PDF Manual provides the complete workshop procedures required to diagnose, repair and maintain the crane according to factory specifications.
Purpose-Built for Large Construction Projects
The 120RT XP is engineered to reduce setup time while maximizing lifting efficiency. Its six-section boom offers excellent working range, while the optional SmartFly attachment and lattice inserts expand lifting flexibility. Pulse 2.0 provides intuitive crane monitoring, and the centralized hydraulic pressure station simplifies routine diagnostics for service technicians. These features make the crane a preferred choice for contractors handling critical lifts in confined or uneven terrain.
