Overhead Crane Design Drawing

NUCLEON 50 Ton Double Girder Overhead Foundry Charging Overhead Crane Design Drawing Structure:

The casting Overhead crane is mainly composed of bridge, crab, connecting traverse, trolley mechanism and electric part. The main hook employs the constant –spacing connecting traverse as the load handling device to hoist steel ladle and the auxiliary hook acts in concert with the main hook to accomplish pouring of molten steel slag, and other auxiliary hoisting.

The trolley travelling mechanism and main electric equipment are installed in the girder. The girder’s electric panel room employs rock wool for heat insulation, and has an air cooler inside. To reduce heat radiation of molten steel to metal structural members, a thermal baffle is set along the span direction at the bottom of the girder.

The trolley travelling mechanism adopts four-corner drive.

The casting Overhead crane Overall structure can be divided into:

double girder double-track, four beams and for-track, four-beam rail and other types. The first two are generally used for large tonnage crane, and the third is generally used for large tonnage of foundry crane.

1,Mainly consists of bridge trolley hook beam, crane travelling and electric part, etc.;

2,Adopt double-girder structure below 125t and four-girder structure above 125t

3,The main grabbing device of main hook is fixedspacing hook girder used to lift foundry ladle

4,Auxiliary hook is used to work with main hook to dump the molten iron and do other subsidiary lifting operation

5,Main hoisting and transportation equipment in steel mill and smelter workshop;

6,Usd for transshipment and pouring of liquid metal during melting, etc;

7,Add thermal-protective coating under the main girder;

8,Ambient temperature: below 60°C, moisture: less than 50%;

9,Crane assembly and test accord with No. 375, 2007 document issued by AQSIQ.
