1. Whole set crane

1) Double Girder EOT (Electric Overhead Traveling) crane is a type of crane that is commonly used in heavy industrial applications that require lifting and moving of large and heavy loads. As the name suggests, the crane has two overhead girders that support a trolley and hoist system, which can move along the length of the crane.

2) Double Girder EOT cranes are generally used to lift and move heavy loads up to 200 tons and can operate in outdoor or indoor environments. They are available in a variety of configurations, including top-running and under-running models, with different lifting heights, spans and working speeds.

3) These cranes are commonly used in industries such as steel, cement, mining, and shipyards, where they are used to move bulky and heavy materials. They are also used in construction sites, warehouses, and logistics companies for lifting and transporting heavy machinery and equipment.

4) In addition to their versatile applications, Double Girder EOT cranes offer benefits such as high load capacity, high lifting height, excellent load stability, and low maintenance. They are designed to provide safe and efficient material handling operations and are an essential part of many heavy industries.

 

2. Main girder

The main girder is the main supporting beam of a double girder EOT (electric overhead traveling) crane. It is the part of the crane that carries the hoisting mechanism, trolley, and other loads. Made from steel, the main girder is engineered to withstand the weight of the loads and the stresses exerted by the crane during operation. Double girder EOT cranes are commonly used for heavy-duty applications, such as in steel mills, shipyards, and container terminals, where large and bulky loads need to be lifted and moved over long distances. The double girder design allows for higher lifting

heights and heavier capacities, providing greater flexibility and efficiency in material handling.

 

3. Lifting System

1) Double Girder EOT (Electric Overhead Traveling) Crane lifting system is a heavy-duty crane used for lifting and moving extremely heavy loads in industrial applications. It is designed to have two parallel load-bearing beams which are fixed on top of a gantry. These beams are also known as girders.

2) The lifting mechanism of the crane is comprised of a hoist or winch that is attached to the girders, allowing it to move up and down along the length of the crane. The crane operator can utilize the hoist to lift and move heavy loads such as steel beams, concrete slabs, or machinery with great precision and ease.

3) The Double Girder EOT Crane lifting system is powered by electricity, and its operation is controlled by the use of a pendant or wireless remote control. It is typically used in manufacturing plants, warehouses, and construction sites where heavy materials require lifting and moving.

4) The advantages of the Double Girder EOT Crane lifting system include its ability to lift heavy loads, its precision handling, and its ability to operate in tight spaces in industrial facilities. It is also known for its durability and long lifespan, making it a cost-effective choice for businesses needing to move heavy loads.

5. Crane traveling mechanism

1) The traveling mechanism of a Double Girder EOT (Electric Overhead Travelling) Crane is responsible for the movement of the crane on tracks or rails. It consists of two sets of wheels with electric motors, which are placed on both sides of the crane's two girders. The wheels are driven by the motors, and move the entire crane across the length of the runway beams.

2) The traveling mechanism is designed to provide smooth and stable movement for the crane, even when carrying heavy loads. The speed of the movement can be adjusted using variable frequency drives, depending on the requirements of the project.

3) The Double Girder EOT Crane is used extensively in large-scale industrial applications, such as in construction sites, shipyards, and manufacturing plants, where the crane needs to lift and move heavy materials or equipment. The traveling mechanism is an essential component of the crane, ensuring that it can move quickly and efficiently to meet the requirements of the job.

 

6. Trolley traversing mechanism

The double girder EOT crane trolley traversing mechanism is a device used to move the trolley along the length of the crane bridge. The trolley is mounted on two parallel, horizontal girders, which are supported by the crane bridge. The traversing mechanism is typically comprised of two motors that drive the trolley wheels along the girders. The motors are controlled by a central control panel, which is operated by the crane operator. The trolley traversing mechanism allows the crane to move materials in a horizontal direction, which is essential for loading and unloading items from different points along the crane bridge. The double girder design provides greater stability and lifting capacity than a single girder crane, making it ideal for heavy-duty applications.

 

7. Crane wheel

1) Double girder electric hoist bridge crane wheel refers to the wheels installed on the bridge beam of a double girder electric hoist bridge crane. The crane wheels are responsible for the movement of the bridge beam along the runway rails, allowing the crane to travel horizontally across the working area. These wheels are typically made of forged steel or cast iron, and are designed to withstand the weight of the crane and its load. The wheels are often equipped with bearings or lubrication systems to ensure smooth operation and reduce wear and tear. Proper maintenance and inspection of the crane wheels is essential for safe and efficient operation of the crane.

2) The corner box type wheel sets are all led out by oil pipes, which is convenient for oiling and maintenance

The wheel material adopts ZG340-640, and is subjected to advanced power frequency heat treatment and quenching

 

8. Crane hook

Double girder EOT crane crane hook is a component of a double girder EOT crane that is used to lift and move heavy loads. It is attached to the hoist and traverses along the bridge girder of the crane using a trolley. The crane hook is designed to fit the lifting requirements of the intended load, and it typically has a safety latch to prevent accidental disengagement of the load. The hook is typically made of high-strength steel to withstand the weight of the load it carries. As the crane hoist lifts the load, the hook securely grasps the load without any slippage. The crane hook is an essential component of the EOT crane, and it is crucial to ensure proper inspection and maintenance of the hook to ensure the safety of the crane operation.

 

9. Motor

1) The motor used in a double girder electric hoist bridge crane is typically an AC squirrel cage motor. These motors are efficient, reliable, and have a long service life. They are designed to provide smooth and uninterrupted power to the crane, ensuring efficient operation and lifting performance.

2) Double girder EOT (Electric Overhead Traveling) crane motor is an electric motor used to drive the motion of a double girder EOT crane. This type of crane motor is designed to provide high lifting capacity and durability, making it suitable for heavy-duty industrial applications. The motor's power rating, speed, and control features will vary based on the specific requirements of the application. Other factors that will affect the performance of the crane motor include the quality of the electrical supply, the design and materials of the crane, the load capacity, and the environmental conditions of the location where the crane will be used. It is important to choose a suitable motor based on these factors to ensure that the crane performs optimally and safely.

 

10. Sound and light alarm system & limit switch& safety parts

1) Every crane will be equipped a sound and light alarm system and so that it is an effective way to keep people safe in emergency situations. It is important to ensure that the system is regularly tested and maintained to ensure that it is in good working order.

2) The limit switch can be widely used in three - dimensional control and travel limitation of hoisting machinery, and it can protect the crane.
