Key Components and Structure of Double Girder Overhead Cranes

Double girder overhead cranes are essential material handling tools used in a variety of industries for lifting and moving heavy loads with precision and efficiency. Understanding their key components and structure is vital to grasp how these cranes operate and how they can optimize industrial processes.

Bridge Girders:

The most prominent feature of a double girder overhead crane is its bridge, which consists of two horizontal girders placed at the top. These girders are typically made of steel and run parallel to each other. They provide structural support and create the bridge that spans the width of the working area.

End Trucks:

At each end of the bridge girders, there are end trucks, which house the wheels that run along the crane’s runway(Купить мостовой кран). End trucks are equipped with a motor and drive mechanism that facilitate the horizontal movement of the crane along the runway. They ensure the crane can traverse the entire length of the working area.

Runway System:

The crane operates on a runway system, consisting of rails or tracks that are mounted on the supporting structure of the building. The runway system provides a path for the crane to travel along the length of the working area. It’s essential for the precise movement and safe of the crane (Двухбалочный мостовой кран).

Electrical System:

The electrical system of a double girder overhead crane is a complex network of components. It includes the power supply, control panel, pendant or remote control device, and various sensors. The electrical system is responsible for all crane operations, including lifting, lowering, trolley movement, and safety functions.

Safety Features:

Safety is a paramount consideration in the design of double girder overhead cranes. They are equipped with numerous safety features, including overload protection systems, emergency stop buttons, limit switches, and anti-sway technology. These features enhance the crane’s safety and reliability during operation.

Control Mechanism:

Modern double girder overhead cranes are equipped with advanced control mechanisms that ensure precise and safe operation. The operator can control the crane’s movements using a pendant or remote control device, which communicates with the crane’s electrical system(мостовой кран цена). The controls offer fine-tuned operation and the ability to handle heavy loads with accuracy.

They are equipped with numerous safety features, including overload protection systems, emergency stop buttons, limit switches, and anti-sway technology. These features enhance the crane’s safety and reliability during operation.

Load Handling Attachments:

To accommodate various types of loads, double girder cranes can be equipped with a variety of load handling attachments. These attachments include hooks, lifting magnets, and specialized lifting fixtures tailored to the specific application and material being handled.

Hoist and Trolley:

The hoist is the component responsible for lifting and lowering the load. It’s attached to a trolley that moves horizontally along the bridge girders. The trolley’s movement is controlled by a motor and allows for the accurate placement of the load. Double girder cranes(Мостовой кран 30 т) are equipped with two hoists for increased lifting capacity and stability.

Structural Design:

The structural design of double girder overhead cranes is robust and engineered for durability. The materials used, such as high-quality steel, ensure the crane can handle heavy loads without deformation. The design of the bridge and end trucks is optimized for maximum stability.

Capacity and Span:

Double girder overhead cranes come in a range of capacities and spans to meet the specific needs of different industries and applications. The span is the distance between the runway beams, and the capacity defines the maximum weight the crane can lift.
