A gantry crane, also known as a bridge crane, is a type of crane with a bridge that is supported on the ground by two side legs along the track.
Composed structurally of the gantry, large vehicle running mechanism, crane trolley, and electrical parts, etc.
Some gantry cranes have a leg only on one side, supported by the factory or pier on the other, known as semi-gantry cranes.
The overhead bridge of the gantry crane, including the main beam and end beam, the support legs, and the lower cross beam, etc., constitutes the structure.
To expand the crane's operational range, the main girder can extend beyond the outriggers on one or both sides, forming a jib.
Also, a crane trolley with an arm can be used to expand the crane's working range through the tilting and rotation of the arm.
