Features:

Heavy duty overhead crane for ironwork allows for high full load rate and high full load frequency. The load-up state is Q3 or Q4. Therefore, the working classification grade of the heavy duty overhead crane for ironwork is between A7 and A8.
From the overall structure, the heavy duty overhead crane for ironwork can be divided into various types: double-girder double rail, four-girder four rail, four-girder six rail and other types. The first two types are generally used for medium and large tonnage casting machines, and the third one is generally used for extra-large tonnage casting cranes.
The heavy duty overhead crane for ironwork is mainly composed of five parts: the main trolley, the sub-trolley, the bridge structure, the cart operating mechanism, the gantry hook group, and the electric drive device and electric control device.
The fixed gantry hook group is suspended on the main trolley by wire ropes, and the distance between the two board hooks is fixed to finish the lifting of the ladle.
The two trolleys can be individually operated to complete various lifting operations, and can also be used in combination to complete the tipping of steel ladle, the disposal of residual steel and slag treatment.
All the mechanisms of the cranes are equipped with limit switches to ensure safety during operation.
Our heavy duty overhead crane can offer these following functions for users' choice of: rotatable lifting appliance; convertible hook distance of the gantry hook; the weight and display of the load.
