The MG Truss Gantry Crane is a heavy-duty lifting device primarily used in outdoor environments. Its open truss structure allows for easy inspection and maintenance of all components.
The frame of the MG truss gantry crane is composed of triangular configurations, forming a robust structure. It is capable of bearing heavy loads and adapting to various complex working conditions.
MG truss gantry cranes are typically portable. They can be moved within a facility or between work sites, making them ideal for temporary installations or locations where a fixed gantry crane cannot be installed. This type of truss gantry crane is widely used and offers numerous advantages.
Double-girder truss gantry cranes play a vital role in bridge construction, transporting building materials, and installing heavy equipment.
Widely used in industries such as automobile manufacturing, shipbuilding, and steel production for loading, unloading, and handling goods on production lines.
In power plants and nuclear facilities, they assist with equipment installation and maintenance.
Ideal for material handling in large-scale construction projects, especially where wide coverage and high load capacity are required.
