Product Description

Double girder overhead cranes are important tools and equipment for mechanization and automation of production processes in modern industrial production and lifting and transportation. They are widely used in indoor and outdoor industrial and mining enterprises, steel, metallurgy and other industries. Double girder overhead cranes consist of two parallel main beams, which provide additional support and stability. This design enables the crane to carry heavier loads while maintaining a strong and durable structure. This type of crane is usually equipped with more complex lifting and running mechanisms and can operate over a wider range. Compared with single girder overhead cranes, the double-girder design can achieve higher lifting speeds and larger spans, covering a larger working area.

Characteristics

Main Girder

The two horizontal beams that span the crane’s width and support the hoist, trolley, and load. These girders bear the weight of the load and distribute it evenly, allowing for greater lifting capacities and spans than single girder designs.

End Trucks

Located on both ends of the bridge girders, end trucks house wheels that run on the crane runway rails. They enable the bridge to move along the length of the runway, allowing for horizontal movement of the crane.
Trolley

The mechanism that moves along the girders, carrying the hoist. The trolley provides lateral movement for the hoist, enabling precise positioning of the load.

Runway Rails

The tracks along which the end trucks travel, usually installed on the building’s structure or columns. These rails allow for smooth, horizontal movement of the crane across the workspace.
Electric Motor and Drive System

Motors provide the power needed for the crane’s movements, including lifting, trolley, and bridge travel. The drive system includes gearing and drives that manage the speed and direction of these movements.

Electrical Panel

A central hub for all electrical components, it houses controls, switches, and circuit breakers to regulate power distribution and crane functions.

Advantages

1 High Load Capacity: Capable of lifting and moving very heavy loads securely and efficiently.
2 Precise Handling: Advanced control systems allow for precise handling and placement of materials.
3 Enhanced Stability: Double girder design provides better stability and support compared to single girder cranes.
4 Versatility: Suitable for a wide range of lifting applications in various industries.

Application

1 Manufacturing Plants: For lifting and transporting heavy machinery and components.
2 Warehouses: For handling large and heavy goods.
3 Construction Sites: For moving construction materials and equipment.
4 Maintenance Facilities: For lifting and positioning heavy parts and equipment during repair and maintenance operations.
