SAC2500S

The seven-stage boom structure and fully optimized U-shape high-strength structural steel boom ensure more uniform pressure and lighter weight, the lifting capacity of key structural components has been optimized, ahead of the tonnage of similar products.

Powerful Lifting Capacity

With the max. boom length of 73m and lifting height of 73.5m, it leads the industry.

Efficient Hydraulic Control Technology

Stable and high-quality hydraulic components such as the main oil pump, main valve, winch motor, slewing motor and balance valve improve the system reliability; superior control performance is ensured through the accurate parameter matching. The slewing system is equipped with an integrated slewing buffer valve with free slipping function, which allows for stable slewing and control and superior micro-mobility.

Safety and Reliability

The load moment limiter calculation system is established based on the lifting model. Through the on-line no-load calibration, the rated lifting accuracy is 5%, providing the all-round protection for the lifting operation. When the overload operation is performed, the system automatically provides the alarm to safeguard the operation. Length, angle and pressure sensors are configured to display the real-time operating status of crane, and automatically cut off the dangerous motion and sound the buzzer.
