New China Sany 55 Ton Mobile Truck Crane Stc550

Sany STC550 truck crane is equipped with more safety 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 heightlimiters respectively to prevent over-hoisting of wire rope.

Powerful Lifting Capacity

The 55 ton truck crane has five-section boom of high strength steel structure and optimized U-shaped cross section with max.lifting capacity of 55t, full-extended boom length of 43m, jib length of 16m, max.lifting height including jib of 59.2m, 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.

Efficient & Unique Hydraulic System

Load feedback and constant power control is applied to provide strong lifting capacity and good micro-mobility. Unique steering buffer design is adopted to ensure stable braking operation.Hydraulic system is configured with the balance valve, overflow valve and two-way hydraulic lock etc.to ensure stable and reliable operation.

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 specialfor 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 themonitoring 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.
