Features of ladle cranes

Ladle cranes are designed to be operated efficiently, uninterruptedly and safely in continuous use. The design conforms to the requirements of international standards.

1.  Used in steel plant for special craft
2.  Very reliable, stabel travelling, convenient maintance
3.  Good in usability, long service life
4.  High loading ability, high working class

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.

Ladle Crane Application

1.  It is designed based on the QD type overhead crane.
2.  Mainly used for transporting, pouring, and charging liquid metal during the smelting process.
3.  Crane assembly and test accord with No. 375, 2007 document issued by AQSIQ.

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).

Ladle Crane Specification and Description

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.
