Light foundry bridge crane & heavy duty foundry overhead crane

Depending on the needs of the user and the operation conditions, foundry cranes are classified as either double-beam single trolley, four-beam, or four-track double trolley. It can use a four-beam six-track double-trolley structure for super large tonnage casting bridge cranes.

The foundry overhead crane crane is made up of the main trolley, the auxiliary trolley, the bridge frame, the trolley operating mechanism, the gantry hook group, and the electric control.

Light  foundry bridge crane

The bridge foundry crane with hook is primarily used to lift molten metal. The overall working class of the machine is A 7, and a thermal-protective coating has been added to the bottom of the main girder. The crane was assembled and tested in accordance with the document No.ZJBT [2007]375 issued by the People's Republic of China's General Administration of Quality Supervision, Inspection, and Quarantine.

Heavy duty foundry crane

It is primarily used for pouring molten iron from the additive bay to the converter and lifting molten steel from the refining bay to the refining furnace or the casting machine's ladle turret. Foundry cranes have the following overall structures: two-girder and two-rail, four-girder and four-rail, four-girder and six-rail, and so on. The top two forms are primarily used for foundry cranes of medium and large tonnage. The last type of crane is primarily used for extra large-ton foundry cranes.

Environmental conditions of foundry crane

• Crane power is three-phase alternating current; the rated frequency is 50 hertz; and the rated voltage is 380 volts.
• The working temperature ranges from -10°C to +60°C.
• When the temperature is +40°C, the relative humidity is no more than 50%.
• If the requirements exceed those listed above, it must follow the terms of the purchase contract.

Conventional scheme

• Taking the enclosed cab
• The YZR insulating motor
• The maximum ambient temperature for working is 60°C.
• Collocate with the advanced electric and the winch is make with the welding's steel board
• The detent gear box and the ratchet wheel

Optional

• Using a wireless remote control to achieve long-distance control.
• Control types can be optional based on user’s requirement and application conditions
• Can be repaired with an air conditioner, a cold air blower, an interphone, and an electronic balance.
• The foundry bridge crane hook size can be customized to meet the needs of the client.

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.

Precautions for foundry crane operation

The Foundry Crane is a processed overhead crane used to lift and lower the steel (iron) liquid ladle. It is an essential piece of manufacturing equipment in the metallurgical casting industry. It is suitable for metal smelting, rolling, and other types of thermal processing. Furthermore, it is a specialized crane that is directly used in the metallurgical casting and casting production processes.

Operating a foundry crane is a dangerous job. To ensure safe production, the absolute safety of the equipment must first be ensured.

If one of these two fails, for example, the wire rope of the casting crane or the sling, the consequences are unimaginable. The consequences are also more severe if the ladle appears to penetrate the steel.

The second factor is personnel quality. A major error by the crane operator or the ground commander will have serious consequences. These are the most fundamental requirements.

In addition to these, there are some other factors to consider:

• A bridge crane route should be established for the location where the ladle passes on the ground, i.e., a flat and dry passage on the ground free of debris sufficient to pass the ladle. It will not be dumped, and the molten steel will not be spilled, reducing the likelihood of an accident. The goal of drying is to keep molten steel from exploding after it has been spilled.
• Ground personnel are not permitted to move, stay, or rest in the overhead crane route area, and personnel are not permitted to compete with the crane to reduce the possibility of accidents.
• Various lounges and conference rooms should be located as far away from the crane route as possible in order to avoid serious accidents involving mass deaths and injuries caused by ladle falling accidents.
• When the heavy ladle of the casting crane is waiting, the height of the ladle from the ground should be limited to no more than one meter.

Notes for foundry crane drivers:

• Getting on and off the cab is more important if it is in the car. Pay attention to the surroundings and the condition of the cab door, and exchange information with the handover personnel when changing shifts. If it is a remote control crane, you must inspect it before taking over (the remote control should still be in the hands of the driver at work at this time, if you want to check on the car, you must pay attention to information communication).
• It also depends on the type of hoisting work for which your foundry crane is primarily responsible. You should be cautious when hoisting liquid metal, especially when hoisting the steelmaking furnace and subsequent processes, such as the crane responsible for charging the converter. Avoid splashing in the converter. The risk factor is extremely high, whether it is molten iron or scrap steel. Accidents have occurred in steelmaking plants all over the world.
• Others are relatively safe, primarily for communicating information and confirming safety with those who assist with the operation.
• Finally, carefully review the factory's safety procedures and documents. Follow the operating procedures to the letter.
