YZS 225/65 ton four-beam casting overhead crane, span 27 meters

CATEGORIES

Casting crane is the main equipment in the steelmaking continuous casting process, mainly used for lifting and transferring liquid steel ladles. From the overall structure, it can be divided into: double beam double track, four beam four track, four beam six track. The first two are generally used for medium and large tonnage casting cranes, and the third is generally used for extra-large tonnage casting cranes. The casting cranes designed and manufactured by our company have the characteristics of advanced technology, novel structure, safety and reliability, economical and durable, and simple maintenance.

Detail

Composition and structure of four-beam casting overhead crane

YZS type four-beam metallurgical casting bridge cranes below 125t are generally YZ type double-beam structures, and above 125t are generally YZ type four-beam structures. YZS type adopts main and auxiliary double trolleys, four-beam four-track structure, mainly composed of bridge frame, main trolley, auxiliary trolley, hook beam, trolley running and electrical parts.

Working Principle of Four-beam Casting Overhead Crane

The main trolley of the YZS type four-beam metallurgical casting bridge crane runs on the main beam track outside the bridge frame, and the auxiliary trolley runs on the auxiliary beam track inside the bridge frame. The main trolley's picking device is a hook beam with a fixed spacing, which is used to lift the molten steel ladle. The auxiliary trolley runs under the main trolley. The picking device is a hook, which is used to cooperate with the main hook to dump molten steel, steel slag and other auxiliary lifting operations.

Casting cranes work in harsh environments with high temperature, high dust and harmful gases, and have heat radiation; therefore, they have the characteristics of heat insulation, dust prevention and corrosion resistance. Because the full load rate and full load times of casting cranes are very high, the uninterrupted working time is very long, and the load state is Q3 or Q4, the working level of casting cranes is between A7-A8.
