Product Description

CE Approved Double Girder Truss Gantry Crane

Product Description

A double truss girder gantry crane is an overhead crane built on top of a structure that is supported by freestanding legs, eliminating the need for an overhead runway system. Gantry cranes are built on movable frameworks with wheels that enable the structure to be moved along a track or rail system.
Truss type Gantry Crane is extensively used in the fabrication Industry for handling loads from 10 to 300 tons. With the truss design it is relatively economical to be use whether during relocation, assembly or services. Also with the small area of contact it is suitable to be use in area with strong wind.
We have supplied Truss type Gantry Crane for bridge construction, precast bridge casting yard and other special usage. NANTE Double Box Girder gantry crane are designed with the highest engineering standards for safety and high performance by advanced technology. NANTE manufactures and supplies custom double girder gantry crane with the capacity up to 300 tons and span up to 50 meters for your demands.
