Product Description

Casting bridge 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 traveling 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. 

Working condition

1. Working temperature: -10~+60°C, 
2. the relative humidity is no more than 50% when the temperature is +40°C; 
3. Work class: A6/A7
4. Power Source: 3ph, 380V, 50HZ or As per customer requirement. 

Parts of the Overhead Casting Crane

1.Main Girder
It contains girder box, platform, pantograph and trolley rail. It applies shot blasting and high quality painting, well-chosen steel plate, advanced welding technology and equipment. 

It consists of motor, reducer, brake, trolley frame, drum, hook, pulley etc. The trolley includes lifting mechanism and cross traveling mechanism. The trolley is strictly designed according to the application and working environment. 

3.End Beam
It works as long traveling mechanism and combines with beam, wheel, motor, reducer, brake and other parts. The steel plate adopt shot blasting, high quality painting and material. The end beam are on bearing beams. 

4.Electric Parts
We choose high quality electric parts with rain cover. The power supply is conductor bar. We could offer the top brand of electric parts, such as: Siemens.
