Description

QDY Double-Girder Metallurgical Overhead Crane

Metallurgy overhead crane is one of the main equipment in the continuous casting technology of steel making. It is mainly used transfer the pouring melted iron to the appointed place, and the thermal-protective coating is added at the bottom of the main girder.

QDY metallurgy overhead crane weight utilized for medium to heavy fabrication. These overhead cranes are ideally suited to casting factory. QDY metallurgy overhead crane are used to move steel or iron ladles in steel smelting workshop with high temperature and a lot of dust.Corrventional scheme:using the closed cab. QDY metallurgy overhead crane weight is widely used in the smelting industry to convey, pour and charge the liquid hot metal in the process of smelting.

Metallurgical bridge cranes are suitable for the production and handling of ladle or molten metal liquids in metallurgical workshops, forging workshops, smelting workshops, foundry workshops, etc.

Advantages

• Double sets of independent action brakes is installed to the lifting mechanism.
• Heavy hammer and rotary lifting position limiters is installed and down position limiter will be installed when crane hoisting height is more than 20 m.
• Over speed protection equipment is stalled of the Ladle Crane.
• Fault protection devices are installed on the Ladle Crane, such as, positive and negative contactor is installed to prevent dangerous in case of electricity power off.
• Insulating layer is installed at the bottom of main girders of the Ladle Crane to prevent molten steel thermal radiation to ensure the long serving life of main girders.
• Special designed metallurgy motor is used on the casting, with insulation class H level, and motor protection grade IP54.
