The bridge erecting machine is widely used in the construction of high-speed railway, but due to the different complexity of the working conditions of different projects, the structure and performance requirements of the bridge erecting machine are also different. At present, the bridge erecting machine can be divided into six categories from two aspects of structure and operation. Next, Tieshan Lifting will take everyone to understand the bridge erecting machine and master the tips of purchasing the bridge erecting machine in the construction of high-speed railway.

Six categories and advantages and disadvantages of bridge erecting machine

1. Lower guide beam bridge erecting machine. It belongs to the tail feed beam and is a step-type through hole. The front leg must be anchored firmly when erecting the beam, and the process is complicated when erecting into the last hole of the tunnel.

2. Guide beam type fixed point lifting bridge erecting machine. The beam erection method belongs to fixed-point lifting, step-type through hole. The front leg must be anchored firmly when erecting the beam, and the process is complicated when erecting into the last hole of the tunnel.

3. Two-span continuous assembled bridge erecting machine. The girder truck camel transports the box girder directly into the tail span of the bridge erecting machine, and the cantilever passes through the hole. The front legs do not need to be anchored to the pier when erecting the girder. The construction process has high economic benefit and low cost.

4. Two-span continuous box girder bridge erecting machine. The beam feeding method, beam erecting steps and through hole method are the same as those of the two-span continuous assembled bridge erecting machine. The bar assembly type girder is changed to the welded box girder structure, which improves the overall assembly speed, is easy to maintain, and has higher work efficiency.

5, freight integrated bridge machine. It is convenient for the hanging beam to pass through the tunnel and erect the beam. Due to the different body structure, different integrated bridge machine in the erection into the last hole of the tunnel will also appear simple and convenient and difficult and complex two situations, the cost is relatively high, the comprehensive operation efficiency is not high.

6, can turn the contraction type over the tunnel box girder bridge machine. The height and width of the crane truck can be changed to ensure smooth passage through the tunnel, and the tunnel can be carried by the beam truck or cross the tunnel by itself, thus saving the cost and time of crossing the tunnel. Suitable for multi-tunnel lines, but the cost is very high.

Tieshan crane teaches you to buy high-speed rail bridge erecting machine4 small tips:

1. Choose the appropriate bridge erecting machine according to the working conditions and weather. Different structure, performance of the bridge machine, to adapt to the construction environment, work efficiency, the degree of operation are different, according to the working conditions to choose the appropriate bridge machine, do not have to pursue too low price or the pursuit of new equipment.

2. Pay attention to the safety protection and monitoring measures of the bridge erecting machine. For large-scale lifting equipment, safety protection and monitoring are very important. The equipment needs to have emergency stop, overspeed protection and other devices to prevent subsequent accidents caused by wrong operation.

3, according to the budget, construction period to buy bridge machine. Need to consider not only the cost of equipment procurement, but also the fuel consumption of the operation process, labor costs, supporting equipment costs. For example, the new bridge erecting machine does not need to lay additional tracks, and the bearings can be reversed and moved, saving labor costs and time, reducing the intensity of manual work, and greatly speeding up the construction period.

4-Quality. As a large-scale hoisting equipment, the quality is the top priority. In the process of purchasing, we must have a detailed understanding of the comprehensive strength of the manufacturer, the production process, the fineness of the product, the scientific rationality of the product structure, and so on.
