This double girder semi-Gantry Crane is supported by one side leg, while the other side is commonly supported by walls or steel structure of workshop/warehouse. The double girder Semi-Gantry Crane is employed to handle stuff outdoors. The A type supporting legs under the main girder runs on the ground rail/track.
1. Lattice girder:
The lattice girder is welded of angle steel or I type steel with the advantage of low cost, light weight, better wind resistance, but because of more welding point, large deflection, small stiffness, lower reliability, the truss type gantry crane is suitable for the fields with lower safety requirements and smaller lifting weight.
2. Box girder:
The box structure is welded of steel plate with features of high security, big stiffness, which is generally applied to the operation of large tonnage stuff, while the box girder has the shortcomings of high cost, big self-weight, and poor wind resistance.
3. Box double girder:
Double girder semi-gantry crane have the features of big lifting capacity, big span, good overall stability, various types, but the self-weight is larger than the other Single Girder Gantry Crane with the same lifting capacity.
