AQ-YZ Double Girder Overhead Casting Crane

AQ-YZ type double girder casting crane is the main overhead lifting equipment used for steelmaking and continuous casting process. The crane offers great protection and high-level efficiency in areas where the high temperature and dust present. It can lift and transport liquid steel ladle in a greater speed and efficiency than its single girder counterpart, making it ideal for heavy duty or severe lifting requirements.

The crane is capable of lifting a substantial amount of weight, usually is a range of 5 tons to 320 tons, and the work duty is A6-A8. Thus the double girder casting crane can adapt to a much worse working environment.

Common  Uses of Casting Bridge Crane

This particular double girder overhead crane is extensively used in many industrial fields, such as steel mills, petrochemical plants, foundries, power plants and other general industries. The environmental conditions where the crane is employed are severe, such as high heat and dust. And also the ladle crane undertakes frequent and heavy duty lifting tasks in such environments.

Basically the temperature of the crane working environment is -10~ + 60℃, and when the temperature reaches +40℃, the relatively humidity should be no more than 50%.

Optimal Design of Steel Mill Casting Crane

Main beam – insulation layer will be added to the bottom of the main beam so as to provide excellent resistance to heat and protect the crane bridge girder.

Hoist trolley – this unit uses forged hook and steel core wire rope. The hoisting mechanism adopts double brakes to ensure a safe lifting operation. Other options for crane hook include rotary spreader, load weighing and display.

Crane travelling mechanism – forged or rolled wheels are adopted.

Electrical device – the overhead crane adopts H-class insulation motor and heat resistant cables.

Cabin – add insulation layer to the driver’s cabin.
