STC500C5-8 SANY TRUCK CRANE
Product Brief Description
The five-section boom of STC550C5-8 adopts high-strength steel structure and optimized U-shaped cross-section, which significantly reduces weight and has a higher safety rate. Jib mounting angles are 0°, 15°, and 30°, which ensures fast and convenient change-over between different operating conditions so as to improving the working efficiency of the machine.
Loading feedback of hydraulic system, constant power control, piston pump and the electrical control valve is applied to provide strong lifting capacity and good micro-mobility. A unique steering buffer design is adopted to ensure stable braking operation.
