About the Link-Belt HTC-825S
The HTC-825S combines a compact transport profile with a high-strength rectangular boom fabricated from 100,000 psi steel and supported by hydraulic telescoping and wear shoe guidance. A bi-directional hydraulic swing drive, pressure-compensated hydraulic system and hydraulic outriggers provide smooth lifting performance, while the modular crane design allows major components to be repaired individually, reducing downtime during scheduled maintenance.
