The dual-girder design supports spans of 20–40 meters, while the electric hoist system enables precise load positioning. Equipped with frequency conversion control and anti-sway technology, it ensures smooth operation even under heavy loads. Safety features include overload protection, limit switches, and emergency stops, complying with GB/T 3811 and FEM 1.001 standards. Ideal for steel mills, heavy machinery manufacturing, and shipyards, these cranes offer optional features like remote control, high-temperature resistance, and specialized attachments for unique applications.
