50 Ton Ladle Foundry And Casting Steel Mill QDY Overhead Bridge Building Crane Design
General description of double girder overhead crane
QDY type double beam overhead foundry crane is one of the main equipment in the continuous casting technology of steel manufacturing. It is mainly used for smelting metal transporter, casting and hot metal charging.
QDY type double beam overhead foundry crane is composed of boxed bridge frame, hook, crane travelling mechanism and electric system. The main hook employs a load tool as the lifting device to hoist steel ladle, the auxiliary hook cooperate with the main hook to accomplish pouring of molten steel and steel slag, and other auxiliary hoisting.
QDY type double beam overhead foundry crane travelling mechanism and main electric equipment are installed in the boxed girder, which employs rock wool for heat insulation, and has an air cooler inside. To reduce heat radiation of molten structural members, a thermal baffle is set along the span direction at the bottom of the girder.
