QDY Ladle Overhead Crane introduction
According to the crane structure, the ladle overhead cranes can be classified into Double Girder Double Rail Ladle Cranes, Four Girder Four Rail Ladle Cranes, and Four Girder Six Rails Ladle Cranes. The front two types are used for lifting middle and large scale ladles, and the latter one is used for extremely large scale ladles.
Production Features
Due to a high risk level, ladle cranes are designed with special safety features to ensure the efficiency and safety of crane system. The features of ladle cranes are as follow:
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.
Fault protection devices, 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 to prevent molten steel thermal radiation to ensure the long serving life of main girders.
Special designed metallurgy motor is used, with insulation class H level, and motor protection grade IP54.
Cast steel pulley is used to ensure the safety and long working life.
Steel core wire rope is used, which is suitable for high temperature environment with the safety factor≧ 7.1.
High temperature resistant cable is used for the power supply of trolley.
Thermal insulation layer and air conditioning is equipped to the cabin.
