Breaking the 30-year efficiency bottleneck of traditional loading/unloading equipment, this quay crane pioneers cross-over dual-trolley technology, integrating intelligent dynamic vibration damping, energy-saving systems, and intelligent control system (ECS) to achieve automatic operations. It improves operational efficiency by over 50% and reduces energy consumption by 20% compared to traditional quay cranes, becoming a key solution for upgrading core loading/unloading equipment in container terminals.
