500t Double Girder Overhead Crane

Ultra-Heavy Casting Fabrication & Assembly Heavy machinery EPC contractors and large foundries frequently find traditional high-tonnage cranes suffer severe load swing during trolley travel. The shaking increases alignment difficulty, raises collision risks and slows down production throughput. Our Overhead Crane cuts workpiece swing amplitude by over72% during travelling. Dual hook design lets the 500t main hook handle massive castings while the 100t auxiliary hook manages smaller attachments. This reduces each hoisting cycle time by approximately38%. If your site also requires outdoor yard lifting solutions, we can bundle Portal Crane into your project order.
