The double girder overhead crane features two main girders that run parallel to each other and are connected by cross beams. The girders are typically made of structural steel and are designed to withstand the weight of the load and the stresses during operation.
The end trucks are located at each end of the crane and support the girders. They are equipped with wheels or rollers that allow the crane to move along rails or tracks. The end trucks also house the drive mechanisms, such as motors and gearboxes, that power the crane's movements.
A hoist and trolley assembly is mounted on the girders and is responsible for lifting and moving the load. The hoist is the lifting device that is attached to a trolley, which runs horizontally along the girders. The hoist and trolley system can be electrically or manually operated, depending on the specific requirements.
Compared to single girder cranes, double girder overhead cranes are capable of spanning longer distances. With a double girder configuration, the crane is structurally more rigid, enabling it to cover larger areas or workstations within a facility.
The double girder design also offers a higher hook height compared to single girder cranes. This allows for greater vertical lift and improved flexibility in handling taller loads or working in facilities with higher ceilings.
Double girder overhead cranes can be customized to meet specific application requirements. They can be tailored in terms of load capacity, span, lifting height, speed, and control options. This flexibility allows the crane to be optimized for various industrial sectors and unique operational needs.
Span: The span refers to the distance between the centers of the two parallel girders. It determines the coverage area of the crane and is typically specified in meters or feet. The span can vary based on the specific requirements of the application.
Lifting Height: The lifting height indicates the vertical distance between the hook or lifting device and the floor. It is an important parameter that determines the maximum height to which the crane can lift the load. Lifting height can be customized based on the specific requirements of the application and the available building height.
Lifting Speed: The lifting speed refers to the rate at which the load can be raised or lowered. It is typically specified in meters per minute (m/min) or feet per minute (ft/min). The lifting speed can vary depending on the load capacity and application requirements.
Manufacturing and Assembly
Double girder overhead cranes are commonly used in manufacturing facilities to handle heavy components, machinery, and equipment during production and assembly processes. They are utilized in various industries, including automotive, aerospace, steel, and general manufacturing.
Power Plants
Power plants rely on double girder overhead cranes for maintenance and installation tasks. These cranes are capable of lifting and positioning heavy equipment, such as turbines, generators, transformers, and large pipes, required for power generation.
Shipbuilding and Ports
The shipbuilding industry extensively uses double girder overhead cranes for handling heavy ship components, loading and unloading cargo, and moving large ship sections during construction. Ports also employ these cranes for effectively handling containers and other materials.
Construction and Infrastructure Projects
In construction sites and infrastructure projects, double girder overhead cranes are utilized to lift and transport heavy construction materials, precast concrete elements, steel structures, and other components. These cranes are well-suited for use in tight and confined spaces, making them ideal for urban construction sites.
