How to choose the right foundry crane?
During the operation of the overhead crane, the number of wheels on the trolley traveling has no effect on the main box structure. The difference between 8 wheels and 4 wheels lies in the different wheel pressures applied by each wheel set to the running track. Simply put, there are 8 wheels. The diameter of the wheel set is relatively small, and the diameter of the four wheel sets is relatively large. The design of the 8 wheel sets is mainly to make the average wheel pressure exerted by the crane on the track more even.

Foundry crane specifications
Foundry cranes are used to lift molten metal. The operating environment has the characteristics of high temperature and high dust. The working level is relatively high, generally at A7, and the high may reach A8. The reliability requirements of casting cranes are much higher than those of common bridge cranes, because once the casting crane fails, it may cause greater losses and serious consequences.

Foundry bridge crane operation
Foundry crane is one of the key equipment in the steel making process. It is mainly used to charge molten iron and molten steel into the converter in the converter charging section, and to lift the ladle to the continuous casting ladle turntable in the receiving section or to the refining furnace in the refining section.
The crane works in a harsh environment with high temperature, high dust and harmful gases, and has heat radiation; therefore, it has the characteristics of heat insulation, dust resistance and corrosion resistance.
Due to the high full load rate and full load times of the foundry crane.
The uninterrupted working time is long.
The working level of the crane is between A6 and A8.
What is foundry crane?
According to user requirements and crane operation conditions. The casting cranes are generally divided into double-beam single trolley, four-beam and four-track double-small vehicles. For super large tonnage casting bridge cranes, it can adopt the four-beam six-track double-trolley structure.
The crane is mainly composed of main trolley, auxiliary trolley, bridge frame, trolley operating mechanism, gantry hook group and electric control.
Hook: The fixed gantry hook group is suspended on the main trolley through steel wire ropes. The two plate hooks has fixed operation at intervals to lift the ladle.
Trolley: The two trolleys can operate independently to complete various hoisting operations. It can also be used in conjunction to complete ladle turnover, residual steel pouring and waste slag operations.
Safety operation system
The main hook is a fixed-spacing hook beam. It has the applications to lift the ladle. The auxiliary hook has the cooperate with the main hook to dump molten iron and other auxiliary functions. The operating mechanism of the trolley and the main electrical equipment are installed in the main beam. The electrical room of the main beam is insulated with rock wool and equipped with air coolers.
In order to reduce the heat radiation of the molten steel to the metal structural parts, a heat insulation board is arranged along the span direction at the bottom of the main beam. The trolleyoperating mechanism adopts four-corner drive. The crane is equipped with an electronic scale, and there are obvious display devices in the driver’s cabin and on the bridge frame.
Foundry crane reducer
There are no special requirements for the reducer. The main lifting requirement for braking is convenient. The casting crane must use double brakes, that is, the hook must be the same as the hook of the general bridge crane. The casting crane for special lifting liquid metal hook.
