The double girder overhead crane is a powerful lifting equipment that has gained popularity in various industrial applications. It is known for its ability to lift heavy loads and transport them across large distances with ease. In this article, we will discuss the double girder overhead crane, its components, and how it works.
What is a Double Girder Overhead Crane?
A double girder overhead crane is a type of overhead crane(мостовой кран) that has two girders instead of one. The girders are parallel to each other and are supported by columns or walls. The double girder design allows for greater lifting capacity and longer spans than single girder cranes.
Components of a Double Girder Overhead Crane
The double girder overhead crane consists of several components, including:
Bridge – The bridge is the main horizontal beam that supports the trolley and hoist. It is made up of the two girders that run parallel to each other.
End Carriages – The end carriages are the components that support the bridge and allow it to move along the runway. They are typically made of steel and have wheels that ride on the rails of the runway.
Hoist – The hoist is the component that lifts and lowers the load. It consists of a motor, gearbox, drum, and wire rope or chain.
Trolley – The trolley is the component that moves the hoist horizontally along the bridge. It is attached to the hoist and moves along the rails of the bridge.
Controls – The controls are the components that allow the operator to control the movement of the crane. They can be located on the crane or on a remote control.
How Does a Double Girder Overhead Crane Work?
The double girder overhead crane(кран мостовой двухбалочный) works by lifting the load with the hoist and moving it horizontally along the bridge with the trolley. The end carriages support the bridge and allow it to move along the runway.
To operate the crane, the operator uses the controls to move the trolley and hoist along the bridge. The hoist can lift the load to the desired height and move it horizontally across the bridge to the desired location.
The double girder design allows for greater lifting capacity and longer spans than single girder cranes. It is ideal for heavy lifting applications such as in steel mills, shipyards, and automotive plants.
Advantages of a Double Girder Overhead Crane
Greater Lifting Capacity – The double girder design allows for greater lifting capacity than single girder cranes(кран мостовой однобалочный). This makes it ideal for heavy lifting applications.
Longer Spans – The double girder design allows for longer spans than single girder cranes. This makes it ideal for applications that require the crane to transport loads across large distances.
More Durability – The double girder design is more durable than single girder cranes. It is designed to withstand heavy loads and constant use.
More Safety – The double girder design provides more safety than single girder cranes. It is designed to prevent accidents such as overloading and tipping.
Applications of a Double Girder Overhead Crane
The double girder overhead crane is used in various industries, including:
Steel Mills – The double girder overhead crane is ideal for moving and lifting heavy steel products such as coils, sheets, and plates.
Shipbuilding – The double girder overhead crane is used to move and lift heavy ship components such as engines, propellers, and hulls.
Automotive – The double girder overhead crane is used in automotive plants to move and lift heavy car parts such as engines, transmissions, and body frames.
Construction – The double girder overhead crane is used in construction sites to lift heavy materials such as steel beams and concrete.
