Advanced Telescopic Cylinder System
This crane adopts an optimized two-section telescopic hydraulic cylinder design. One cylinder drives the main boom extension, while another operates the telescopic boom through a wire rope and pulley block mechanism. This structure improves lifting efficiency, extension stability, and load control, while effectively protecting the internal wire rope system, ensuring longer service life and reduced maintenance.
High-Strength Structural Boom Design
The crane features a symmetrical center structure combined with pentagonal and hexagonal boom profiles, significantly enhancing torsional rigidity, anti-buckling strength, and structural stability. This reinforced design allows the crane to maintain safe lifting performance even under heavy loads and frequent operating conditions.
Reinforced High-Strength Steel Construction
The boom connection interface is manufactured using thick high-strength steel plates, improving the crane’s load-bearing capacity, resistance to deformation, and overall durability. This robust construction ensures the crane can perform reliably in heavy-duty lifting environments and demanding job sites.
Efficient and Low-Noise Hydraulic System
The crane is equipped with a high-performance hydraulic lifting mechanism that delivers smooth, precise, and stable lifting operations. The optimized hydraulic design reduces operating noise, improves energy efficiency, and enhances overall working comfort, making it suitable for urban construction sites, industrial facilities, and continuous lifting tasks.
Flexible Mobile Lifting Solution
With its truck-mounted compact design and 360° slewing capability, the TENGCHANG 6.3 Ton crane provides excellent mobility, easy installation on transport trucks, and flexible operation in confined workspaces, offering customers a powerful, efficient, and cost-effective mobile lifting solution.
