About the Link-Belt HTC-822S
The HTC-822S was engineered to deliver greater boom reach and lifting flexibility while maintaining excellent highway travel characteristics. Its four-section boom utilizes Link-Belt's high-strength box construction with hydraulic telescoping and integral holding valves for smooth, controlled operation. The modular design allows major components—including the swing drive, hydraulic pumps, hoists and boom cylinders—to be serviced individually, helping reduce maintenance costs and equipment downtime.
