HD100 Bailey panel bridge is a type of
bridge system that can be dissembled and rapidly erected. It was designed
according to British Compact-100 Bailey Bridge. The whole bridge is welded with
high-tensile strength steel. The girder is light weight composite panels and
the panels are connected by panel connection pins. The conversion between the
parts is easy and they are lightweight. It is easy to assemble or disassemble
and transport them. It can also be assembled into different forms of panel
bridges according to their span length and transportation requirement. So, it
has been widely applied as a more developed and guaranteed panel bridges for
emergency transportation.
Because the deck is
thin and transom beam is light, It is suitable for that when the requested
bridge span or loading are small.

The HD200 panel
bridge is similar to the HD100 panel bridge from their appearance. The
difference is its increased panel height to 2.134m. For some bridge with longer
spans, It employed the method of alternating joints between Reinforcement
Chords and the joints between panels. This method can decrease inelastic
deformation caused by the oversized pinholes. Pre-arch method is used to
additionally cut down mid-span and vertical deflection to a larger degree.
Bolt-connected components use the orienting sleeve- fixing method to increase
accuracy of connections. Shear is created in orienting sleeves and tension is
developed in bolts, which increase the usage life of the bolts and ensure the
safety of panel bridges. Wind resistant brace is made to be composite type and
is connected to transom/girders to improve overall stability of panel bridges.
The part between braced frame and panels is fixed through bridging so as to
prevent the whole bridge from side bending. After the erection, there will be a
pre-arched degree over the span of the bridge. Besides it can be assembled into
single-lane bridges. The compact 200 panel bridge can also be assembled into
double lane bridge, hence it broadens its application range. It is suitable for
the load designs of HS-15, HS-20, HS-25 ,HL-93 and pedrail-50 etc.

GWD modular
bridge was invited from Germany and has advantage in the long-span and big
loading comparing to bailey bridge. Thus, it can save cost of piers.
Its panel
chord is bigger than bailey bridge panel but the panel structure is simpler. All
the components are bolted so the bridge can be used as a permanent bridge
because of its small deflection..The components are interchangeable and
repetitively used.This kind of bridge has various structure changes to satisfy
different loading capacity.

Upon years of
discussion and collaboration, PB100 Modular footbridge has applied the
advantages of Bailey bridge and optimal choice of material in its projects.
EVERCROSS Steam have been entrusted to develop and design a light-weighted
PB100 Modular footbridge. The bridge design has been given due considerations
to the demand of function, natural environmental condition, technical
feasibility, material transportation and cost etc. As the requirement on
loading was smaller, the structural members of the bailey panel could be
re-designed to a lighter weight, meeting its needs on economic, transportation,
construction and other means. With the premise of ensuring
safety, PB100 Modular footbridge excels the conventional Bailey bridge
limitations as mentioned and it has its unique advantage of application in the
PB100 Modular footbridge projects.
