Features

 

High Load Capacity and Stability:

The Double Girder Gantry Crane's load-bearing capacity is greatly increased by the use of two parallel girders in its construction. Large and bulky materials may be handled by the crane because to its design, which makes it easy to lift and move huge loads. Even with the largest loads, the crane's overall stability is improved by the dual-girder arrangement, guaranteeing safe and efficient operation.

 

Extended Span and Lifting Height:

Compared to single girder cranes, the double girder construction of this crane allows it to cover broader spans and reach higher lifting heights. For applications requiring lifting over wide regions or handling tall or piled objects, this makes it the perfect choice. There is no need for additional cranes or equipment because to the expanded span capacity, which guarantees effective coverage of large work areas.

Adaptable to Diverse Uses:

Double Girder Gantry Cranes may be made to specifically suit the requirements of various businesses and activities. Customization possibilities include different heights, lifting capabilities, and spans in addition to the incorporation of specialist lifting attachments such spreader beams, magnets, and grabs. Because of its adaptability, the crane may be used for a variety of operations, including container handling, outdoor logistics, heavy manufacturing, and assembly.

 

Durability and Long Service Life:

The Double Girder Gantry Crane is made to last a long time since it is made of premium materials and is made to handle difficult working environments. A long service life is guaranteed by the sturdy structure, which minimizes wear and tear and the need for frequent maintenance.

Gantry Structure

Main Girders: The double girder design consists of two parallel horizontal beams, typically made from steel. These girders are the primary load-bearing elements of the crane, providing the strength and stability required to lift and transport heavy loads. The girders are connected by a cross beam, which enhances the overall structural integrity.

Legs (Supports): The girders are supported by two or more vertical legs that extend down to the ground. These legs are usually equipped with wheels, allowing the crane to move along a predefined path. The legs provide the necessary height for the crane to clear obstacles and handle materials at various levels.

End Carriages

Wheels and Rail System: The end carriages are the sections at the ends of the girders that house the wheels and drive mechanisms. These wheels run on rails or tracks, allowing the crane to move back and forth along its designated path. The wheels can be rubber-tired for outdoor or non-rail applications, or steel for running on rail tracks.

Drive Mechanism: The movement of the crane is powered by motors located in the end carriages. These motors drive the wheels and enable the crane to travel along its path, providing the horizontal motion needed to position the crane over the load.

Hoist and Trolley

Hoist: The hoist is the lifting mechanism that raises and lowers the load. In a double girder gantry crane, the hoist is typically mounted on a trolley that moves along the length of the girders. The hoist consists of a motor, drum, and wire rope or chain. The motor powers the drum, which winds the rope or chain to lift or lower the load.

Trolley: The trolley travels horizontally along the main girders, carrying the hoist and the load it is lifting. The trolley is equipped with wheels that run on rails mounted on the
girders. The movement of the trolley allows the crane to position the hoist directly above the load, providing precise control over the lifting operation.

Control System

Operator Cabin: In larger gantry cranes, an operator cabin may be provided. This cabin is typically mounted on one of the girders or on a separate structure attached to the crane. From the cabin, the operator can control all aspects of the crane's operation, including movement, lifting, and safety systems.

Remote Control: Many modern double girder gantry cranes are equipped with wireless remote controls, allowing the operator to control the crane from a distance. This enhances safety and flexibility, as the operator
can move to a safe vantage point while controlling the crane.

Automation and PLCs: Some cranes are equipped with programmable logic controllers (PLCs) and automated systems that can perform predefined lifting and positioning tasks with minimal human intervention. These systems improve efficiency and reduce the potential for human error.
