Construction Use Double Girder Truss Type Launching Gantry
Product Description
Construction Use Double Girder Truss Type Launching Gantry erection crane is generally used in the erection of the Highway Bridge and Subway Bridge, using the precast segmental prestress concrete box beam (PC beam) assembly. The main feature is the high efficiency of construction and self-traveling. Generally it is composed of the main beam, leg and winch trolley, the main girder is used for bearing, the leg is to execute machine transverse moving, longitudinal moving, leveling, support, cross span, cross scale and other functions, and the winch trolley used for lifting the precast girder.
