Ladle Crane: Key Equipment in Steel Casting
Ladle Crane, or casting crane, is the main equipment in the continuous casting process of steel manufacturing, mainly used to lift and transfer liquid steel (iron) ladle. Structurally, it is mainly divided into double-beam double-track, four-beam four-track and four-beam six-track types. Among them, double-beam double-track and four-beam four-track are generally used for medium and large tonnage casting cranes, while four-beam six-track is mainly used for large tonnage casting cranes.
The design and manufacture of Ladle Crane embodies the characteristics of advanced technology, novel structure, safety and reliability, economic durability and easy maintenance. These cranes have a high working level (such as A7) and perform well in harsh working environments (high temperature from -10℃ to +60℃, high dust and harmful gases). In order to meet these harsh conditions, they need to be dust-proof and anti-corrosion treated.
Application and Improvement
Four-beam Casting Overhead Crane
Ladle cranes are designed to be operated efficiently, uninterruptedly and safely in continuous use. The design conforms to the requirements of international standards.
Our company mainly manufactures ladle cranes with lifting capacity of 5~550t, span of 10.5m~31.5m, lifting height of 1m-30m, working class（A7), also can design and manufacture according to requirements.
It is applicable in the temperature of -10℃～+60℃, Humidity≤85%; if the temperature is below +60℃, humidity ≤50%. Altitude below 1000m, Power is 3-phase 380v 50HZ(also can be customized according to customer's requirements).
Mark：for example, ladle crane with lifting capacity of 20/5t，span of 10.5m , it is QDY20/5t-10.5m.
Note：If some items are without marks，such as lifting height、type of cabin and entry direction、rail type、crane conductor、Mechanism working class、air conditioner etc. it should instruct in the contract or product technical drawing.
Ladle Crane mainly composed of bridge frame, trolley, traveling mechanism and electrical equipments.
Note：The main hook is used for lifting steel ladle, the aux. hook is used for lifting other goods; It is not allowed for Main and AUX. hooks to lift two different goods at the same time. When separate working, it is not allowed to exceed the rated lifting capacity of main and aux. Hook. Working at the same time, it is not allowed to exceed the rated lifting capacity of main hook.
Note: Control mode for cab operation
