span by span segmental concrete box girder bridge construction launching gantry Span by span segmental concrete box girder bridge construction launching gantry span by span segmental concrete box girder bridge construction launching gantry is generally used in the erection of the Highway Bridge and Subway Bridge, using the precast segmental pre-stress concrete box beam (PC beam) assembly. The main feature is the high efficiency of construction and self-traveling. Generally span by span segmental concrete box girder bridge construction launching gantry 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. Our company: Henan Huada Heavy Industry is a big enterprise specialized in researching, developing, producing and exporting. It mainly produces span by span segmental concrete box girder bridge construction launching gantry and all kinds of accessories, which widely cover machinery, metallurgy, electric power, railway, water conservancy, ports, terminals and other industries. Our advantages: A. More than 50 R&D personnels with advanced Science and technology B. More than 400 sets advanced Production processing equipment and inspection equipment C. Independent intellectual property rights to develop energy saving bridge cranes, gantry cranes, and electric hoist E. Obtain ISO 9001 certificate and more than 10 series of patent certificates F. Efficient service and competitive products G. Export more than 100 countries Packing 1. Electric and hydraulic parts are packed by high quality plywood crate to reduce distortion in conveying; 2. Main beams, end beams are packed by plastic woven cloth. It can reduce abrasion when transport. Delivery 1.If the size of span by span segmental concrete box girder bridge construction launching gantry are suitable for container ship, usually by container; 2.If the size is too big, usually by bulk ship or by container after disassembly. Transport ways are based on reducing cost for you and keep the crane performance. Transportation Generally 35 days to 50 days to destination port.
