This machine can combine 900 ton tyre trolley to work for double-line high speed Railway Bridge with box beams in the length of 20m, 24m and 32m.

1）Working environment and condition
·Launching concrete box beam with same length span or different length span, with ballast or without ballast.
·Different height of the concrete box beam in one bridge
· Surmountable slope 3 %
· Min. radius of the bridge 1400m
·Wind speed: 72km/h with load, 144km/h without load.
2）Main technical characteristics
· When the launching gantry finishes placing concrete beams and the under bridge tries to launch forward，the whole machine is driven by the chain system of the small trolley under the launching leg. That can ensure a stable movement, and will never create additional force movement to the gantry.
· When the location of machine assembly is close to the launching jobsite, the launching gantry can move to the abutment itself and can also place itself on the pier to be ready to erect concrete box beams.
· After finishing erecting the concrete beam of one bridge, the launching gantry can move forward by itself on the deck or go through the existing deck or steel bridge.
· With the help of special transporting frame, the launching gantry can be moved on the railway basement or deck by tyre trolley.
·When it is necessary to go through certain areas with height limits or some narrow areas such as tunnels, the machine can be partly disassembled to reduce its section dimension. Then with the help of transporting the frame, the launching gantry can pass the limited area.

Q:How does the bridging machine work?: I saw at the site of the bridge building machine, its main principle is: (methods, mainly introduced the first beam behind it in between the land bridge was) and the first and the second piers of the bridge pier, the establishment of six pivot, and then put the prefabricated beam from the prefabricated plant shipped between the land and the first pier place

Q:Bridging machine inspection which information and what departments to go? Ah!!!!!!: First, the export of mechanical products must be declared by the manufacturer in the local entry-exit inspection and Quarantine Bureau of quality inspection, inspection, will be issued by the commodity inspection certificate or commodity inspection release

Q:Now the high-speed rail bridge frame span of the beam: But it is very different from the general sense of the crane. The requirements of the harsh conditions, and the existence of the beam on the line, or called the longitudinal shift. Bridge machine is divided into the erection of highway bridges, conventional railway bridge, passenger dedicated railway bridge, etc..

Q:What is the technical parameter of 30m/100t fixed guide beam of bridge erector?: Car (horizontal) walking speed (m/min) 3.15 3.15 3.15Bridge machine through hole velocity (m/min) 5.566Beam transport flat car speed (m/min) beam flat car speed 6.6m/min, return speed 13m/min (variable frequency speed)Deflection of work (mm) maximum deflection 706034Longitudinal forward cantilever deflection 800630350Adaptive bending radius (m) 350300200To adapt to the incline angle of 0~45 degrees 0~45 degrees 0~45Machine power ~104kw ~92kw ~77kw

Q:What should be done before the erection of the bridge girder: But it is very different from the general sense of the crane. The requirements of the harsh conditions, and the existence of the beam on the line, or called the longitudinal shift.

Q:Our original home is the height of the beam is now 3m to 2.6 of the beam is not to the bridge before the support leg height: The front leg is to reduce a certain height. Do not know who you are using the bridge machine, and some of the front legs of the bridge machine can be dismantled section, and some have spiral support, so, but also with the design manufacturers, can not change their own. Once you have it, in case of any problems, the designer has no responsibility.

Q:Detection and quality standard of bridge erecting machine: Double cantilever girder erecting machineBridge construction machinery, the use of the Soviet Union earlier. In 1948 the introduction of the front and rear arm with steel beam, lifting weight of 45 tons and 80 tons of two kinds. In 50s, the two arms to the framework, lifting to 130 tons.

Q:When does the bridge machine not belong to the gantry crane?: The bridge erecting machine is a device for placing a prefabricated beam on a prefabricated pier

Q:Operating rules for bridge erecting machines: Six, after the erection of the bridge crane must be suspended hanging crane operation, but also can be used to test the concrete beam, bridge erection machine running in place to start the installation work.Seven, bridging machine installation work, we should pay attention to the safety inspection, each installation of a hole must conduct a comprehensive safety inspection, found the problem to stop working and timely processing to continue to work. Do not allow mechanical and electrical failure.Eight, the installation operation is not allowed to overload operation, shall not lift operation.Nine, connecting pin processing materials must be carried out according to the requirements of design drawings, shall not use the low grade instead of processing.

Q:Bridge machine has a sale of the code, used to query the bridge machine related information, is generally how much: Haha I ask for the people is the single beam type car English crane inspector is referred to as LD (LD also has different types of small classification) rn (model + + tonnage span) is the number of single girder crane
