Link-Belt HTC-1170 Crane Service PDF Manual
The Link-Belt HTC-1170 is a high-performance 70 U.S. ton (63.5 metric ton) hydraulic truck crane developed for heavy lifting applications including bridge construction, refinery projects, steel erection, power generation facilities and large industrial installations. Built with a 38 ft–120 ft four-section full-power telescopic boom, an optional offset lattice fly, hydraulic planetary winches and a rugged 6×4 highway carrier, the HTC-1170 delivers outstanding lifting capacity, long reach and reliable roadability. This OEM Factory Service PDF Manual provides complete workshop repair procedures, hydraulic diagnostics, electrical troubleshooting, component overhaul instructions and factory inspection specifications for professional maintenance.
About the Link-Belt HTC-1170
The HTC-1170 features a pressure-compensated hydraulic system that allows multiple crane functions to operate simultaneously while maintaining smooth and accurate load control. Its modular carrier and upper structure simplify servicing by allowing major components—including hydraulic pumps, steering assemblies, swing drives, hoists and boom sections—to be repaired independently. The OEM service manual includes factory disassembly procedures, hydraulic schematics, adjustment specifications and operational testing methods to help technicians restore the crane to original Link-Belt performance.
