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
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.
