150T Truss Type Double Girder Gantry Crane with Open WinchProduct
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
