Overhead Crane Block

1. Product Introduction:

Double girder overhead crane block

 

Double girder overhead crane block applicable to iron and steel metallurgy, hydropower, aerospace, shipbuilding, automobile, coal, petrochemical industry

 

Casting crane is the main equipment in the steelmaking continuous casting process. It is mainly used for lifting and transferring liquid steel ladles. From the overall structure, it can be divided into double-beam double-track, four-beam four-track, four-beam six-track and other types. The first two are generally used for medium and large tonnage casting cranes, and the third is generally used for extra-large tonnage casting cranes. The casting cranes designed and manufactured by our company have the characteristics of advanced technology, novel structure, safety and reliability, economical and durable, and simple maintenance. In addition, our casting cranes can provide the following functions for users to choose:

 

1. Rotatable hoist

 

2. Variable gantry hook distance

 

3. Load weighing and display

 

2. Parameters:

 

Double-beam bridge crane is mainly composed of bridge, trolley running mechanism, trolley, electrical equipment, etc. According to the frequency of use, it is divided into three working levels: A5, A6, and A7. The operation of the hook bridge crane is all completed by the driver. Main parameters of double-beam bridge crane:

 

1. Lifting capacity: 5-10 tons, 16/3.2-50/10 tons, 75/20-100/20 tons, 100/32 tons 125/30-250/50 tons, 300/40 tons, 350/75 tons, 400/80 tons, 600/150 tons

 

2. Span: 10.5-31.5 meters, 13-31 meters.

 

3. Lifting height: 6-22 meters.

3. Component:

 

Casting double beam crane is a special equipment used for heavy lifting and unloading in foundry workshops or similar places. Its components include main beam, auxiliary beam, traveling mechanism, lifting mechanism, electrical system, etc.

 

4. Applicable Environment:

Metallurgical cranes are mainly used for special cranes for metal smelting, rolling and hot processing. They include open-hearth charging bridge cranes, overhead cranes, traveling cranes, ground charging cranes, material box cranes, ingot stripping cranes, mold cranes, cover cranes, clamp cranes, slab turning cranes, forging cranes, heating furnace loading and unloading cranes, material box-electromagnetic cranes, and material box-grab cranes. Other similar metallurgical cranes can also be used for reference.

5. Wearing Parts:

 

Rope guides, Travel switches, Travel limiters and Brake.

 

6. Environmental conditions for use:

 

The design and manufacture of metallurgical cranes (hereinafter referred to as cranes) shall comply with the relevant provisions of GB3811, this standard and product drawings.

 

Environmental conditions

 

The power supply of the crane is generally three-phase AC, with a frequency of 50Hz and a voltage of 380V. The upper limit of the allowable voltage fluctuation on the motor and electrical appliances is +10% of the rated voltage, and the lower limit (at peak current) is -15% of the rated voltage. The internal voltage loss of the crane shall not exceed 5% for ingot stripping cranes, clamp cranes, integral mold cranes with guide frames and slab turning cranes, and shall not exceed 4% for other types of cranes in this standard. If there are special requirements for the power supply, it can be determined by negotiation between the supply and demand parties according to the needs of the user.

 

The altitude of the installation and use site of the crane shall not exceed 2000m (when it exceeds 1000m, the motor capacity shall be checked according to the relevant provisions of GB755).

 

The working environment temperature and humidity of the crane a. The working environment temperature of the crane is generally -10~+50℃. b. The relative humidity shall not exceed 50% at a temperature of +40℃.

 

The site where the crane is used shall not have flammable, explosive and corrosive gases and shall comply with the provisions of relevant standards and documents.

 

The installation of the crane running track shall generally comply with the requirements of GB10183. In case of special circumstances, it may be specified separately as needed.

Bridge cranes, overhead cranes, and traveling cranes are suitable for workshops, warehouses, etc. of factories, mines, and enterprises, and are used for general loading and unloading and lifting and transportation work in fixed spans indoors or outdoors.

 

This machine is divided into two working systems: medium and heavy according to the degree of busyness; the medium is suitable for mechanical processing, metal structure, assembly and other workshops; the heavy is suitable for smelting workshops and handling work in continuous production.

 

This machine consists of four parts: box-shaped bridge frame, trolley running mechanism, trolley, and electrical equipment. All mechanisms are operated in the operating room.

 

When used outdoors, it is equipped with rain protection equipment.

75-500 ton suspension bridge cranes, overhead cranes, and traveling cranes are a series of products manufactured using international advanced standards. The whole machine has novel structure, beautiful shape, good processability, flexible and stable operation, safe and reliable.

 

Advantages and characteristics of double-beam bridge casting crane:

 

The whole machine has novel structure, beautiful shape, good processability, flexible and stable operation, safe and reliable.
