Full Span Truss Type Bridge Girder High Working Efficiency Beam Launcher

 

Product Description

 

Full Span Truss Type Bridge Girder High Working Efficiency Beam Launcher is used for erecting concrete box girders for high speed (250km, 350km) passenger railway lines. This machine is suitable for equal span girders or different span girders which can be 20m, 24m and 32m, 50m. The rear part has two supports. One of the supports is "C" shape column with rotary and foldable technology. The "C" shape column technology saved the traverse space during traveling and which enables to travel through tunnels with the girder transfer vehicle.

 

 

 

Composition system and main beam form of beam bridge erecting machine

 

Full Span Truss Type Bridge Girder High Working Efficiency Beam Launcher is a gantry crane specially designed for bridge construction. Beam elevators are mainly composed of assembled main beams, outriggers, bridge cranes, etc. The components are connected by pins and high-strength bolts for easy disassembly and transportation. Compared with ordinary gantry cranes, it is easy to install and economical and practical. Suitable for the construction of constantly flowing highway bridges.
There are many components in the Full Span Truss Type Bridge Girder High Working Efficiency Beam Launcher , such as the main structure and power system. Each component has its own function. In addition, there are still two modes for the main beam of the beam bridge erection machine, one is a single beam and the other is a double beam. When we operate a beam crane, we need to choose the appropriate method based on our needs.
Comparing the Full Span Truss Type Bridge Girder High Working Efficiency Beam Launcher with the ordinary bridge crane, it is found that there are obvious differences, that is, when the electric hoist is working, the sparks that are not generated or generated are not enough to affect the surrounding environment, so some can be used. Inflammable, explosive, dust and other places.
Even so, when using a double-beam crane, we need to pay attention to its maintenance, especially the motor. For example, for parts removed from a double-girder crane, avoid contamination or wrapping with clean cloth, avoid contamination or wrapping with clean cloth, or place parts in designated containers to prevent loss during operation.
In addition, the disassembly and assembly of the Full Span Truss Type Bridge Girder High Working Efficiency Beam Launcher requires a process, and the operation process is exactly the opposite. During operation, parts that should be taken care of should not be hit or struck, and should not be used as a tool or fulcrum.

 

Beam Launcher operation process

 

  • The required height of the two sides of the longitudinal running track of the bridge crane remains stable. The horizontal running track of the front, middle and rear legs requires level, and the spacing is strictly controlled. The three tracks must be parallel.
  • When installing the concrete beam of the inclined bridge, the front, middle and rear legs of the bridge should be staggered in front and back, and the left and right wheels should be staggered in front and back. The pitch can be calculated based on the tilt angle so that the leg wheels can run on the same lateral track. (For more information, contact the manufacturer).
  • The longitudinal movement of the bridge crane must do all the preparations, and it is required to be in place at one time, and it is not allowed to stop in the middle.
  • When the gantry crane carries the concrete beam longitudinally, the front legs need to be fastened and fixed by chain hoists and horizontal rails to improve stability.
  • When installing bridges with vertical and vertical slopes, measures should be taken to prevent longitudinal displacement of the bridge machinery to prevent slipping.
  • After installing the erection machine, it must be hoisted and tested. After testing with concrete beams, the bridge crane can be put into operation again and the installation work can begin.
  • When installing the bridge crane, pay attention to security inspection at all times. Every time a hole is installed, a comprehensive security inspection is required. If you find that the problem stopped working and deal with it in time, you can continue. Mechanical electrical failure is not allowed to work.
  • Overloading of installation work is not allowed, and tilting and lifting work are not allowed.
  • The processing material of the connecting pin must be carried out in accordance with the requirements of the design drawing, and low-grade steel processing should not be used instead.
  • It is strictly forbidden to operate above the tenth and fifth wind. Rigging must be used to stabilize the bridge crane and lift the crane. When the bridge machine stops working, the power should be cut off to prevent accidents.
  • The longitudinal position of the bridge erecting machine must strictly control the position and size to ensure the smooth installation of the precast concrete beam.
  • Large specialized equipment is installed on the twelve bridge bridge. Bridge machine operation must be clearly divided and unified, and full-time operators, full-time electricians and full-time security inspectors should be established. Strict construction organization and measures to ensure construction security.

Prevent oil leakage

 

In order to effectively prevent the reducer from leaking oil, the manufacturer should upgrade the process level and optimize the design: the ventilation device can be added to the fuel hole cover to ensure the balance of internal and external pressure. At the same time, in the design process, the process accuracy between the joint surfaces of the two boxes should be improved to prevent oil leakage failure due to unsatisfactory contact surfaces.
At the same time, it is necessary to perform maintenance work during daily use. Check the ventilation holes, oil quantity of the gantry crane, ordinary gearboxes and fasteners are normal.
