Ladle Refining Crane

Descripción del producto

Brief Description
Being leading product of our company, the main technical specification of foundry / casting crane / ladle refinin crane, ingot casting crane was drafted according to detailed requirements of many steel plants in the mainland and around world. High working speed of main lifting mechanism is suitable for hot loading and hot transforming to improve work efficiency. Stator variable voltage speed control or frequency speed control can keep the speed within 1~*0m/min or other speed, to be quick moving and precision location.  
Characteristics
Foundry crane design and manufacture by our company has such advantages as safety and reliability, advanced technology, brand new structure, economic and long-term life, easy maintenance and so on.
Crane Type
Types of foundry / casting crane include double girder double rail type, double girder four rail type, four girder four rail type and four girder six rail type. Where double girder double rail and four girder four rail type were mainly used for those of small lifting capacity (below *5t), and the four girder six rail type mainly applicable for those of large lifting capacity (*5t~**0t).
Type of Arrangement for Main Lifting Mechanism
There are 4 types of arrangement for main lifting mechanism according to lifting capacity and mechanism arrangement as double reducer type, large reducer type, 3 reducer type (common) and planetary reducer type.
Wheel Arrangement of Traveling Mechanism
Central arrangement of wheel, which is suitable for the crane with lifting height is not strictly required. Disperse arrangement of wheel, which is applicable for the crane with lifting height is required strictly.
Other Function
- Each mechanism can be variable speed;
- Rotary spreader;
- Distance of portal hook is adjustable;
- Overload limit and alarm;
- Load weight and indicate;
- PLC control, failure inspect, indication, record and print system;
- Anti-collision system to avoid collision between crane in same span;
Main Technical Specification
- Lifting capacity ranged from 5t to **0t.
- The span (from rail-center to rail-center) ranged from *5m to *0m.
- Lifting speed is of variable speed (like 1.*8~*2.8m/min).
- Lifting height can be *8m or as required.
- Trolley traversing speed is depending on the SWL of the crane or the real requirements.
- Traveling speed of the crane can be designed according to customer’s requirements
- Controlled by operator cabin with high-temperature proof cover.
- The working duty is A6~A8.
- Power source for double girder overhead crane is the one of your local power. So, please let me know it when you send your RFQ.
Material for Crane Construct
- Material for general crane construct is Q**5B, which should be changed into Q**5B when the limit temperature is below **0 centigrade.
- Material for crane wheel is *2 CrMo.
- Portal hook for ladle is forged one.
- The steel rope is flexible one or customer’s required.
Component Used on Crane
- Electric motor is well-known one in China, like Jiamusi or other international one like ABB, SEW and so on as customer’s requirement.
- Such important electric components as breaker, contactor, and fuse are of Schneider, Siemens and so on.
- Other ones can be followed according to our customer’s requirement.
