Product Feature

Sany STC750 truck crane adopts load feedback and constant power control technology that is designed to provide strong lifting capacity and good micro-mobility. Unique steering buffer ensures the stable braking operation.

Powerful Lifting Capacity

The 75 ton truck crane has five-section boom of high strength steel structure and optimized U-shaped cross section with max.lifting capacity of 75t, full-extended boom length of 45m, jib length of 16m, max.lifting height including jib of 61m, reduce weight and improve safety significantly.

Jib mounting angles are 0°, 15°, and 30°, which ensure fast and convenient change-over between different operating conditions so as to improve working efficiency of the machine.

Excellent Traveling Performance

Double-axle drive is used to provide good trafficability and comfortableness under complex road condition; engine has the multimode power output function, which reduces power consumption; the use of tipping over early-warning technology provides high stable and safe operation.

Intelligent Electronic Control

Self-developed controller SYMC special for engineering machinery is configured. The adoption of CAN-bus full-digital network control technology ensures stable control signal, simple harness, and high reliability. Timely feedback of data information can achieve the monitoring of the overall working status in real time.

The Load Moment Limiter

Equipped with the comprehensive intelligent protection system is used with accuracy within 5%. The adoption of comprehensive logic and interlock control system ensures more safe and reliable operation.

More Safe Devices

Main and auxiliary winches are equipped with over roll-out limiter to prevent over rolling-out of wire rope.

Boom and jib ends are equipped with height limiters respectively to prevent over-hoisting of wire rope.

Hydraulic system is configured with the balance valve, overflow valve and two-way hydraulic lock etc., to ensure stable and reliable operation.
