Professional Truss Type Segmental Launching Gantry

800 ton segment china launching gantry equipment for bridge construction 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 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.     Product Model SH1600 Max. hanging weight(t) 1600 span(m) 50、51 Lifting height of trolley(m) 56 Rated lifting capacity(t) 140 Max. working slope 2% Max. working transverse slope 2% Traveling speed(m/min) 1 Speed of erection of girder(day/span) 10 The whole machine power(kw) 180 The total weight(k) 750 Huada Heavy Industry is a big enterprise specialized in researching, developing, producing and exporting. It mainly produces 900 ton underslung segment launching gantry manufacturer , overhead crane and gantry crane, beam launcher, movable scaffolding system crane, form traveller, straddle carrier, tyre transporter, beam trolley, portal crane and electric winch, electric hoist and all kinds of accessories, which widely cover machinery, metallurgy, electric power, railway, water conservancy, ports, terminals and other industries. Huada Heavy Industry has more than 600 stuff, and covers 200,000 square meters. 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 parts are packed by high quality plywood crate, to reduce distortion in conveying; 2. Main beams, end beams and electric hoist are packed by plastic woven cloth. It can reduce abrasion when transport. Delivery 1.If the size of 900 ton underslung segment launching gantry manufacturer are suitable for container ship, usually by container; 2.If the size is too big, usually by bulk ship or by container after truncation; Transport ways are based on reducing cost for you and keep the crane performance. Delivery time Within 30 to 40 working days after the receipt of deposit. Transportation Generally 35 days to 50 days to destination port. Huada Heavy Industry launching gantry (LG) Series are designed for safety. Winches are equipped with double breaking system. Upon request we provide Triple breaking system.  Emergency stop button, Limit switch,nsor are located at designated location. Lighting and spare-parts are part of the items coming with 900 ton underslung segment launching gantry manufacturer. Test before shipment   1.What’s the information should I provide when inquiry about the 800 ton segment china launching gantry equipment for bridge construction? a .we need the Bridge Drawing;the Maximum longitudinal slope and the Maximum Transverse slope; b. The Girder/beam drawing;  2.How many Personnel and equipment to assemble launching gantry in the worksite we need？ Personnel: 8 to 10 workers equipment:  Truck crane>50t ：2 sets Φ19.5 steel wire rope 8m：4 ropes Sleepers：several Electric welding machine：1set Oxygen, acetylene：1 set Hammer(12pound and 8pound)：1 set for each Wrench and pincher：several Gradienter：1set                                            3.What are inspection standard for load test of 800 ton segment china launching gantry equipment for bridge construction? a. Dynamic load test 1.1 times rated load, main girder does not down deflection, all mechanisms work well, performance parameters meet the design demand, all limit switches and safety protection interlock devices are reliable, all spare parts does not have cracking and flexible connection, all motors and contactors are not overhead. b. Static load test 1.25times rated load, all mechanisms work well, the crane stops 20min to 30min as trial load is lifted 10cm high, then measure main girder down deflection(theodolite, ruler). Put down trial load to measure main girder upper camber, repeat 3 times, steel structure does not have permanent deformation. 4.How to make highway bridge concrete girders? a.Full span prefabrication, b.Segment girder prefabrication c. Full span cast in place girder d. Segment cast in situ 5.How about maintenance of 800 ton segment china launching gantry equipment for bridge construction? a. Lubricating. b. Steel wire rope. c. Spreader  d. Pulley blocke.Wheels  f. Brake
