Product Description

Product Descriptio
_{Powerful Lifting Capacity}

<sub>STC30 30 ton TRUCK crane has four-section boom of high strength steel structure and optimized U-shaped cross section with
max.lifting capacity of 30T, full-extended boom length of 33.5m, max.lifting height including jib of 42m, 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
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.

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.</sub>
