·         Double-axle drive

·         STC300S Mobile crane uses the load moment limiter. Equipped with the comprehensive intelligent protection system is used with accuracy within 3%. The adoption of comprehensive logic and interlock control system ensures more safe and reliable operation.

· Powerful Lifting Capacity

·The 30t Mobile crane has five-section boom of high strength steel structure and optimized U-shaped cross section with max.lifting capacity of 30t, full-extended boom length of 40.5m, jib length of 8m, max.lifting height including jib of 49m, 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

· Hydraulic system load feedback featuring long service life, high efficiency and low energy consumption is applied to enhance lifting capacity and micro-mobility. Unique steering buffer design is adopted to ensure stable braking 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

· 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.

· 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.
