The construction of the Bailey steel bridge was carried out in strict accordance with the steps

The construction of Bailey steel bridge is carried out in strict accordance with the steps, because the assembly of Berlei steel bridge is not strictly equipped with torsion wrench, so the new operators do not know much about the specific torque, and even think that the harder the tightening, the better. In strengthening the connecting rod bolt also use a long afterrod, beyond the range of bearing capacity of the bolt, directly lead to the deformation of the bolt, so that it is subjected to super impact load, direct fracture. So tighten the connecting rod bolts and don't think the tighter the better.

When the steel bridge is assembled, it is hoisted up by a crane of the right size and placed behind the armed frame. Instead of forming a parallel line, two men use sticks to extend the front of the frame across the joint plate, the belly bar pin hole pointing back, insert the pin, and then extend the back of the truss, insert the chain pin. The Bere Bridge is built to ensure the bending stiffness of the beams.
