Gantry crane is an indispensable lifting machinery in road and bridge engineering. Its name comes from the fact that the structure of the equipment is like a big door frame, so it is called "gantry crane". However, depending on the region and the development of the times, it is called beam lifting machine, gantry crane, gantry crane, gantry crane, etc. So what are these equipment specifically like?
Beam lifting machine: The beam lifting machine used in normal times is common in prefabricated beam yards. The main function of the beam lifting machine in the prefabricated beam yard is to lift beams. The beam pieces in the beam yard include T beams, box beams, plate beams, etc. Hence the name - beam lifting machine. The beam lifting machine is specially used for lifting prefabricated beams. It can be lifted alone or in pairs. Its main walking method is to lay tracks on the ground. Generally, multiple similar projects will be set up on the tracks at the same time. The flower rack structure is more common. The main reason is that the construction period is short, the cost is low, the demolition cost is low, and the cost of the entire project is saved.
Gantry crane: The name of gantry crane is more popular, referring to the gantry crane, which stands on the ground like a door and has legs. Because of its huge size, it is named gantry crane. Gantry cranes are mainly of truss type and box type. They are used for large shipbuilding. The span is generally large. The main beam span is mostly between 10-30 meters and the lifting height is 6-15 meters. All A3-A8 levels can be provided.
3. Portal crane: The scientific name of gantry crane is portal crane, which is also a kind of crane. This type of crane is mainly used for loading and unloading goods at port terminals, but the general cargo yard gantry crane and port gantry crane are of this type. The full name is cargo yard gantry crane, referred to as cargo yard gantry crane, hence the name - gantry crane.
