Casting bridge cranes are the main lifting and transportation equipment in the smelting workshop of steel mills. They are used for the liquid metal transfer, pouring, and hot metal mixing during the smelting process. Below 125t is generally a YZ type double beam structure. Above 125t is generally YZS type four-beam structure. YZS type adopts main and auxiliary double trolleys, four-beam and four-track structures, mainly composed of bridge frame, main trolley, auxiliary trolley, hook beam, crane operation, and electrical parts. The main trolley runs on the main girder track outside the bridge frame, and the auxiliary trolley is on the bridge frame. The inner side auxiliary beam runs on the track, and the main trolley pick-up device is a hook beam with fixed spacing.
The crane can work under the harsh environment such as -25ºC~+60ºC, indoor hot laying and dust. Suitable for steel smelting workshop use.
