Ladle overhead crane introduction
QDY series double girder ladle overhead crane is a heavy lifting equipment used for 5-74t, grade A7, span from 10.5m to 31.5m, Temperature range: -20℃ ～ +60℃.
The QDY type ladle crane is designed for transporting, pouring and charging hot metal in the process of smelting liquid metal, etc.
According to the crane structure, ladle overhead crane can be divided into double-girder double-rail ladle crane, four-girder four-rail ladle crane, four-girder six-rail ladle crane. The first two categories are used for lifting medium and large ladles, while the latter is used to lift extra large ladles.

Features of double girder ladle cranes
Because of the high risk of ladle crane, its design has special safety characteristics to ensure the efficiency and safety of the crane system. The characteristics of ladle cranes are as follows:
■ Install two groups of independent action brakes on the lifting mechanism.
■ Install lower limiter, heavy hammer and rotary lifting and limiting device when hoisting height of crane is greater than 20m.
■ overspeed protection stop device.
■ 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.
■ The motor protection grade IP54, using specially designed metallurgical motors, insulation grade is H grade.
■ Adopting cast steel belt pulley ensures safety and long working life.
■ Steel core wire rope is suitable for high temperature environment with a safety factor.
■ Trolley power supply uses high temperature cable.
■ The crane cabin is equipped with thermal insulation and air conditioning equipment.
