How to dismantle the Bailey panel of Bailey steel bridge

To remove Bailey panel, it is necessary to disconnect Bailey panels in the middle of the span as much as possible, knock out the pins, and then remove each group of Bailey panels in sequence by using a crane. If it cannot be disconnected and dismantled, two cranes can be used to hoist and dismantle the entire group of berets. The berets that cannot be directly lifted and removed by the crane are pulled out synchronously by the inverted chain, and then lifted and removed. For the two spans A157-A158 and A160-A162, as far as possible, break the bailey panel at 15 meters from the center line of the A158 and A160 piers, knock out the pins, and use the crane to remove the shell pieces in sequence. When disconnected for dismantling, two cranes can be used to hoist and dismantle the entire group of berets. Bailey panels that cannot be directly lifted and removed by the crane are pulled out synchronously by the inverted chain, and then lifted and removed.
