Abstract
A dismountable bridge comprises at least one bridge section including a top deck and a bottom boom disposed underneath the top deck. The bottom boom includes a mechanism for adjusting the length of the bottom boom. Rigid end supports each have one end hinged to a respective one of the ends of the top deck and have another end hinged to a respective one of the ends of the bottom boom. Tension elements are disposed laterally of the bridge section and are stressed only tensionally. Each tension element has one end hinged to one end of the top deck and another end hinged to an end of the bottom boom opposite to the one end of the top deck. The bridge section can be changed from a transport position, in which the top deck and the bottom boom are collapsed for maintaining a low height for transporting, and into an operating position in which the top deck is remote from the bottom boom at least at one end of the bridge section.
