Double Girder Beam Gantry Crane

• Bridge construction: The gantry crane is suitable for various large-scale bridge construction projects, especially for projects that require frequent and rapid lifting and installation of beams, such as highway bridges, railway bridges, large urban overpasses, etc.
• Infrastructure scenarios such as high-speed rail, highways, ports, and docks: The gantry crane is often combined with the bridge erecting machine and the beam transport flatbed to form a complete set of operation systems, widely serving these infrastructure scenarios and helping to shorten the construction period.
• Complex environments and high-risk areas: The gantry crane can be flexibly switched between the driver's cab and remote control mode, suitable for remote operation in complex environments or high-risk areas, reducing the risk of personnel working at heights.
• Industrial manufacturing, warehousing and logistics, ports and shipbuilding, construction, mining and quarrying: Lifting machines are used in these fields for lifting and transporting heavy objects, parts, raw materials, etc., improving production efficiency and logistics efficiency, and ensuring the safety of goods and materials.

In summary, double girder beam gantry cranes have been widely used in multiple fields, especially playing a key role in bridge construction and related infrastructure construction.

• Flexible structure and easy disassembly: The lifting machine adopts an assembled design, with the main beam, support legs, overhead crane and other components connected by pin shafts and high-strength bolts, which facilitates transportation, installation, disassembly and reassembly, improving the flexibility and utilization of the equipment.
• Economical and practical, high cost-effectiveness: The design of the lifting machine fully considers economy, has a compact structure, uses reasonable materials, and reduces manufacturing costs. Meanwhile, the convenience of disassembly and assembly reduces transportation and installation costs, resulting in lower overall usage costs.
• Strong lifting capacity and wide adaptability: Different tonnage lifting equipment can be configured according to engineering requirements, which can meet the lifting needs of various heavy objects and adapt to different working environments and terrain conditions.
• Easy to operate, safe and reliable: Modern lifting machines are equipped with advanced control systems and sensors to achieve precise lifting and positioning operations. The operator can complete the operation instructions through the control panel or remote control, and the system has various safety protection functions, such as overload protection, limit protection, etc.
• High degree of automation and improved efficiency: With technological progress, the automation level of lifting machines continues to improve. Some advanced lifting machines have achieved automated or semi automated operations, greatly improving work efficiency and reducing labor costs.
• Easy maintenance and long service life: The structural design of the lifting machine is reasonable, easy to maintain and upkeep, ensuring its long-term stability, reliability, and durability.
• High stability: The lifting gantry crane has a reasonable structural design and high stability during operation, even in complex and changing construction environments, it can maintain stable performance.
• Intelligent operation: Equipped with a new generation of control system, it can achieve precise operation, reducing the difficulty and risk of manual operation.
• Strong adaptability: able to adapt to different construction environments and conditions, whether it is high temperature, low temperature or humid environment, it can maintain stable performance.

In summary, the gantry crane has the advantages and characteristics of flexible structure, economic practicality, strong lifting capacity, easy operation, high degree of automation, and convenient maintenance

Prefabricated beam gantry crane is a type of gantry crane specifically used for bridge construction, and its working principle mainly revolves around the lifting and installation of prefabricated beams. The specific working principle is as follows:

The lifting machine is mainly composed of assembled main beams, supporting legs, overhead cranes, etc. The components are connected by pin shafts and high-strength bolts, which are easy to disassemble, assemble and transport.

The lifting machine is equipped with leg walking, overhead crane walking, and overhead crane lifting equipment, which can achieve all-round mechanized actions. It is mainly used to lift prefabricated beams from the beam making platform to the beam storage platform, and after the maintenance of the prefabricated beams is completed, they are lifted from the beam storage platform to the beam transport vehicle. It is also used to erect dry bridges with low pier bodies.

The beam lifting machine can be used to lift prefabricated beams in combination with two cranes, or a single crane with dual lifting devices can be used to lift prefabricated beams.

The control system of the lifting machine includes operation through the driver's cab and remote control, as well as automation control, to improve the accuracy and efficiency of each action.

In summary, the gantry crane, with its unique structural design and advanced control system, has achieved efficient and precise lifting and installation of prefabricated beams, making it an indispensable and important equipment in modern bridge construction
