三一重工 STC500T

■ 本款吊车三一设计、制造，由细晶粒高强钢板焊接而成的防扭转箱形结构，承载能力强。

■ Designed and manufactured by Sany, the torsion resistant box-type structure is welded by fine grain high-strength steel, featuring increased bearing capacity

■ 吊车卷扬采用高品质马达，作业更高效，重物起落平稳。主卷扬配置三圈保护器，防止钢丝绳过放。

■ High quality winch motor raises working efficiency and hoisting smoothness. Main winch is protected via three-circle indicator, preventing wire rope from over hoist-down.

■ 起重机固定配重5.5t，活动配重3.1t，机动灵活。
■ Fixed CW 5.5t, movable CW 3.1t, to be used flexibly.

■ 起重臂采用高强度结构钢，截面为 U 形大圆弧截面，5 节臂。

■ 起重机全新设计的双变量柱塞泵智能流量分配系统，微动性好

■ Five section boom is welded by high-strength structural steel in U shape cross section.

■ Newly designed smart flow distribution system of double variable piston pump, featuring excellent inching motion.

■基本臂 Basic boom：1590kN·m

■全伸主臂 Full-extension boom：1019kN·m

■全伸主臂+副臂Full-extension boom + jib：312kN·m

臂节数Boom sections (Qty.)：5节U形 U shape

■支腿跨距（纵 × 横）Outrigger span (Longitudinal × Transverse)：5.95×7.2M

■转台尾部回转半径Tail slewing radius：3.7M

■每100公里油耗Fuel consumption per 100km：40L

■采用分析力学方法，建立了基于吊重力学模型的力矩限制器计算系统，通过在线空载标定，吊重精度达到±5%。

■液压系统配置液压平衡阀、溢流阀、双向液压锁等元件，实现液压系统稳定可靠。

■主、副臂臂端配置高度限位器，防止钢丝绳过卷。

■配置长度角度传感器、压力传感器，实时显示起重机作业状态，自动切断危险动作，蜂鸣报警。

■Self developed LMI is set through analytical mechanics approach. Load accuracy is maintained in a range of ±5% via online unloaded calibration.

■Hydraulic balance valve, relief valve, two-way pilot-controlled valve are equipped for hydraulic system reliability.

■Height limit switch at head of boom and fixed jib, preventing wire rope from over-hoist up.

■Boom length & angle sensor and stress sensor help monitor crane working status. Motion of risks are cut off automatically with buzzer warning simultaneously.
