Theloading-bearing main girder system is situated under the bridge, and outsidemould system sits on the loading-bearing main girder. The main girder systemsits on the platform by outrigger, which are anchored on the pier by the highprecision rolling thread steel. Outside mould template opens with the maingirder transversely or opens transversely singly to avoid the pier whilepassing through the hole. The outrigger can perform an auto forward flip or bythe auxiliary crane. Outside mould system can move longitudinally with maingirder. Its clearance under bridge is large and the height of the bridge pieris generally more than 4m, which has a stronger adaptability for high piers.
Performance and parameters：
Applicable spanand girder weight ；40m/1300t
Applicable heightof the bridge pier: 4m
Applicablelongitudinal gradient: 4%
Applicable curveradius: 1000m
Compared with:
Up-slung launching gantry
1) Double main girder andtwo-span structure, more secure, faster. Applicable to the low pier andclearance under bridge is not demanded. Simple construction, needless todismantle the main girder and outside mould parts;
2) Outside mould system opens and closes transversely,original design and ingenious conception;
3) Transverse movement and hoisting is propelled bythe power, easily and fast;
4) Lifting and opening, closing are controlled by thehydraulic pressure, with steady movement which is secure and reliable. Reducethe labor intensity and upgrade the construction efficiency;
5) All the legs can pass through the wholeautomatically and erect, reducing the investment of auxiliary equipments,reducing the construction cost.
Performance and parameters：
Applicable longitudinal gradient: 2.0%
Applicable curve radius: ≥1500m
Requirements for environment wind pressure:
Maximum allowable wind pressure during shifting: 150N/㎡
Maximum allowable wind pressure during casting: 800N/㎡ ( or to be anchored)
Total power by using the whole machine:About 95kw
Kinetic condition: 4Ac, 380v, 50Hz
Hydraulic system pressure: 32Mpa
Shift speed: 0-1.5m/min
Deflection of main girder: Less than L/700( only considering the deflectioncaused by the concrete loading and internal mould weight)
Via Hole Stability Factor: k>1.5
Transportation condition: meet the limits of railway and highwaytransportation.
Unit Weight: About 530t (without separated mould situated in the support)
Construction cycle: 10 days/span
- Q:okay, so my grandpa has this (he calls it a grain wagon) piece of machinery, and he wants to know what year it's from and what exactly also it is, and it's make. Below there is a picture of the emblem on the back of this, and it's like a M that's reflected. I'd appreciate if you could attach a source to your answer...thanks

- When we feel bad we often look to the most recent history for clues when in fact the longer history of our lives must also be accounted for. 40% of all heart attacks first symptom is sudden death. Of the 60% that survive the first attack they recall running to catch someone or shoveling snow or some other circumstance that seemed to trigger the heart attack. So shoveling snow, or running to catch someone is not the cause of the attack. In the same manner your work environment may have some bad things in it. And you need to be careful and research what you are working with. At the same time you also need to consider that many other factors are involved when you suddenly start to feel sick. The sickness of heart disease is reversible. and clogged arteries can be cleared without surgery. But you have to understand how people came to get clogged arteries and how to go about a better way of living. That better way is described in the CHIP program. (CHIP) stands for Coronary Health Improvement Project. You can look for a program near you and the education the program provides will give you a comprehensive view on how to live healthy and feel good in health and body. May God prosper your health,

- Q:What kind of job is a mechanic in the end?
- Mechanical engineer is a person who works in a mechanical engineering field and has some experience and level. Mechanical engineers are generally divided into three levels, Junior Mechanical Engineer, intermediate mechanical engineer, senior mechanical engineer. The mechanical engineer is usually referred to as the three level of mechanical engineers, mechanical engineers can also refer to the intermediate.
- Q:I was reading a thread about chemical engineering and noticed someone said that chemical engineers design machinery used to mass produce products created by chemist. Is this true?
- Yeah they can. Machinery's predominantly designed my mechanical engineers, but it's not uncommon for a chemical engineer to do it too, or do aspects of the overall design.
- Q:Do you know how to operate any machinery?
- Yes, I also know how to operate a calculator too.
