A gantry crane is a type of overhead crane with a single or double girder configuration supported by freestanding legs that move on wheels or along a track or rail system. Larger gantry systems may run on a rail or track embedded in the ground, typically in a straight line in a dedicated work area.
What is the purpose of the gantry crane system?
Gantry cranes are generally used for lifting extremely heavy objects. Because of this, they are often employed during shipbuilding, where the crane straddles the ship to allow for very large jobs, such as lifting the engines into the ship.
What is a girder on a crane?

What is meant by gantry crane?
: a bridge crane in which the beam or bridge is carried at each end by a trestle that travels on tracks on the ground.
Which motor is used in overhead crane?
2. According to crane motor structure and working principle. According to the structurer and working principle, the motors for overhead crane and gantry cranes can be divided into direct current motor (AC motor), induction motors (AC motors), and synchronous motor.
