About the Link-Belt HTC-855
The HTC-855 was designed with serviceability in mind. Its modular construction allows major hydraulic and mechanical assemblies—including steering components, hydraulic pumps, swing drives, hoists and boom sections—to be repaired individually, reducing maintenance costs and downtime. The OEM workshop manual provides detailed disassembly procedures, inspection limits, torque specifications and hydraulic schematics used by professional crane technicians during complete overhauls.
