Liebherr manufactures some of the world's largest and most sophisticated cranes, including Ship-to-Shore (STS) gantry cranes, Rubber Tyred Gantry (RTG) cranes, mobile harbor cranes, and specialized lifting equipment for ports, mining, and heavy industry. These cranes represent the pinnacle of engineering sophistication—and their electrical power systems reflect this advanced design. Most Liebherr cranes operating in Australia specify 1.1kV nominal systems, reflecting Australian IT earthing system philosophy and mining industry requirements. 利勃海尔制造世界上一些最大和最复杂的起重机，包括船对岸(STS)门式起重机、橡胶轮胎门式(RTG)起重机、移动港口起重机和港口、采矿和重工业专用提升设备。这些起重机代表工程精进的最高境界——其电气动力系统反映了这种先进设计。澳洲运营的大多数利勃海尔起重机规范为1.1kV额定值系统，反映了澳洲IT接地系统理念和采矿工业要求。 STS Gantry Cranes: Liebherr STS cranes for container ports (e.g., Sydney, Melbourne, Brisbane) operate at 1.1kV nominal, with power demands up to 500+ kW for hoist and trolley motors. The reeling drum cables must deliver reliable power across frequent 150–200 meter spans with minimal voltage drop. RTG Cranes: Liebherr RTGs for container terminals use 1.1kV systems with 300–400 kW power demand. These mobile cranes require high flexibility—cables are deployed and retracted thousands of times annually during equipment repositioning and container handling operations. Mining Cranes: Liebherr also manufactures specialized mining cranes for ore handling and excavator support. These systems operate at 1.1kV with continuous duty requirements and demanding environmental exposure (dust, temperature extremes, moisture).
