The A-type double-beam gantry crane is an essential lifting equipment for factories, ports, freight yards, and other locations. Its advanced design is primarily intended to meet the needs for loading, unloading, and handling large cargo. The main structure of this gantry crane consists of two parallel main beams and supporting legs at both ends, which support the entire gantry frame and move along ground tracks.
The main beams are connected by end beams, forming a stable frame structure that ensures stability and safety during operation. The two main beams are equipped with running rails for the installation and movement of the lifting trolley, enabling the lifting of cargo. Additionally, this double-beam gantry crane is equipped with a cabin, electrical control system, and safety protection devices to ensure safe and convenient operation. Depending on different practical usage requirements, parameters such as working speed, lifting capacity, and span can be adjusted to suit various working environments and operational demands. It is widely appreciated for its excellent stability, powerful load-bearing capacity, and efficient operational performance.
The electrical control system is crucial for the operation of the gantry crane. It not only manages basic functions such as lifting and traveling, but also adjusts speed and direction, and provides necessary automation features. Our modern gantry cranes integrate advanced computer technology and sensor systems to improve positioning accuracy, optimize load handling processes, and enhance overall safety.
In shipyards, the A-type double-beam gantry crane can lift various parts of the ship's hull, such as hull sections, engines, and other large components.
In logistics centers or warehouses, this type of gantry crane is used for transporting, stacking, and sorting goods, thereby improving space utilization and processing efficiency.
On construction sites, it is used for transporting building materials (such as rebar, cement, bricks, etc.) and installing heavy machinery.
Whether in wind power, thermal power, or nuclear power plants, it is an indispensable tool for assembling and maintaining large energy equipment.
For industries that require the handling of large mechanical components or heavy processing, it provides the necessary lifting capacity and operational flexibility.
