 A truck crane featuring full circle swinging, telescopic luffing jib and electro-hydraulic proportional control;
• The truck crane uses the special 6-axle chassis. Its key components are highly accurate, its weight is lighter than that of other 6-axle all-terrain cranes, its suspension is both simple and reliable, and its steering mode is effective, thus its operation and maintenance costs are reduced;
• Upgraded action control, ideal balance between operating speed, smoothness, and inching performance;
• Upgraded active and passive safety system ensures the safety of personnel, crane during construction.
• The revolutionary innovation of single-cylinder pinning mechanism of boom and telescopic control system, and the technological upgrading of chassis drive, suspension, and steering systems effectively ensures the high reliability and attendance rate of the crane and reduces its maintenance cost.
• Substantially meet the ergonomics requirements imposed by customer;
