Boom Length: 33.5m
Overall Weight: 30000kg
· STC250-IR2 Mobile crane for right hand driving is equipped with four-section boom of high strength steel structure and optimized U-shaped cross section with max.lifting capacity of 25t, full-extended boom length of 33.5m, max.lifting height including jib of 42m, reduce weight and improve safety significantly.
· Powerful Lifting Capacity
· Jib mounting angles of STC250-IR2 25 ton crane 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
·Triple gear pump, load feedback and constant power control are applied to provide strong lifting capacity and good micro-mobility. Unique steering buffer design guarantees smooth braking operation.
· Excellent Traveling Performance
· Double-axle drive is applied to provide good mobility. Trafficability and comfortableness under the complex road condition is improved with reliable traveling performance;
· Engine has the multimode power output function, which reduces power consumption.
· 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 3%. 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.
