The HK800 is an 8.0-ton class telescopic spider crane engineered for the most demanding lifting projects in extremely confined and challenging environments . Designed for easy transport and utmost handiness , this machine can work on slopes, stairs, passageways, and difficult-to-reach places where conventional cranes cannot operate . With a maximum lifting height of 16.8m and a working radius of 14m, it delivers powerful performance without requiring long setup times, saving both time and money while ensuring elevated safety levels.
HK800 Spider Crane
The HK800 represents the pinnacle of Hengwang’s spider crane lineup, offering maximum capacity for heavy lifts in spaces where access is severely limited. Its compact dimensions (5.2m L x 1.5m W x 2.2m H) and robust 6.8-ton machine weight provide a stable foundation for its impressive 8-ton lifting capacity.
This machine is designed to excel in very different places and confined spaces—including slopes, stairs, passageways, and difficult-to-reach locations—without requiring long setup times . It introduces a new and convenient lifting system that ensures savings in terms of time and money as well as elevated safety levels and improved lifting performance .
The HK800 features a dual-power system with both a diesel engine and an electric motor, managed via an integrated power distribution box, offering ultimate flexibility for indoor and outdoor operation. The telescopic boom, controlled by proportional valves and a proportional remote control, provides smooth, precise movements even under heavy load.
