CB100 bailey Panel Pin and Pin Clips

1 Bailey Bridge Component for connecting bailey panel

For connecting trusses. There is one circular hole in one end of the pin. Insert the safety detent while installing so as to preventing the pin form dropping. There is a socket in the pin top, with the direction in conformity with that of small circular aperture. While installing, make the socket parallel the upper & lower chord member, so that the safety detent may be inserted into the pin smoothly.
While erecting triple-row bridge, for the convenience of assembly & removal, pin shall be installed as follows: insert the pin of the first row (interior row) of the lower row of truss from the inside to outside, and from outside to inside of the second and third row. All the pins of the upper row shall be inserted from outside.
The material of truss frame is 30CrMnTi, with the diameter of 49.5mm.

Bailey Bridge Specification

The Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed by the British during World War II for military use and saw extensive use by both British and the American military engineering units.

A Bailey bridge had the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand, without requiring the use of a crane. The bridges were strong enough to carry tanks. Bailey bridges continue to be extensively used in civil engineering construction projects and to provide temporary crossings for foot and vehicle traffic.

The success of the Bailey bridge was due to its unique modular design, and the fact that one could be assembled with minimal aid from heavy equipment. Most, if not all, previous designs for military bridges required cranes to lift the pre-assembled bridge and lower it into place. The Bailey parts were made of standard steel alloys, and were simple enough that parts made at a number of different factories could be completely interchangeable. Each individual part could be carried by a small number of men, enabling army engineers to move more easily and more quickly than before, in preparing the way for troops and matériel advancing behind them. Finally, the modular design allowed engineers to build each bridge to be as long and as strong as needed, doubling or tripling up on the supportive side panels, or on the roadbed sections.
CB100(321-Type) Bailey Bridge  Introduction                                  

Application of Compact 100(CB100;321-Type) standard panel bridge:
Bridge deck width: 4m
Free Span length: 9-51M
Panel Dimension:3000MMX1500MM

The compact 100(CB100;321-Type) panel bridge is a type of bridge system that can be disassembler and rapidly erected. 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. It is suitable for load designs of HS-15, HS-20, HS-25 and pedrail-50 etc.
