1. What are the models and tonnages of bridge erecting machines?
The models of bridge erecting machines are not uniform, because the bridge erecting machines themselves are non-standard products, and each manufacturer All can have their own unique way of naming distinction.
There are many types of bridge erecting machines. According to their uses, they can be roughly divided into highway bridge erecting machines and railway bridge erecting machines. According to different structures, it can be divided into auxiliary guide beam type bridge erecting machine, transporting integrated bridge erecting machine, tunnel type bridge erecting machine and so on. It can also be divided according to the erection method, which can be divided into segmented assembly type, whole hole type, etc. It is also divided according to tonnage. Generally, the tonnage of highway bridge erecting machines is relatively small, generally less than 300 tons. Railway bridge erecting machines, especially high-speed railway bridge erecting machines, generally have relatively large tonnage, with 450 tons and 900 tons being common. There are also bridge erecting machines produced by some manufacturers that can be used for both highway and railway purposes. This type of bridge erecting machine is generally suitable for the erection of bridges on ordinary railways.
In addition, there is another kind of road bridge erecting machine used in very large projects, such as the Hangzhou Bay Bridge (1800 tons), etc. The tonnage of the highway bridge erecting machine is very large. There are few complete hole forms.
2. What is the height of the railway bridge erecting machine?
The railway bridge erecting machine is a large mechanical equipment commonly used in railway construction, and its height is different from other types of mechanical equipment. There are currently four main types of railway bridge erecting machines on the market:
1. Small railway bridge erecting machines: Small railway bridge erecting machines are generally less than 3 meters in height and are suitable for relatively small railway bridges. construction.
2. Medium-sized railway bridge erecting machine: The height of medium-sized railway bridge erecting machine is generally less than 6 meters and is suitable for medium-sized railway bridge construction.
3. Large railway bridge erecting machine: The height of large railway bridge erecting machine is generally more than 10 meters, which is suitable for large-scale railway bridge construction.
4. Ultra-high railway bridge erecting machine: The height of ultra-high railway bridge erecting machine can reach more than 30 meters, which is suitable for the construction of special high-speed railway bridges.
The height of the railway bridge erecting machine directly affects its operating range and construction efficiency. Smaller railway bridge erecting machines can be suitable for simple railway bridge construction, but they are insufficient for difficult construction operations. The use of ultra-high railway bridge erecting machines can not only improve construction efficiency and reduce labor intensity, but also ensure construction quality.
In short, the selection of the height of the railway bridge erecting machine should be based on specific construction needs to achieve the best construction effect and quality.
