Multifunctional experimental bench

A multifunctional testing stand relates to a multifunctional testing stand which operates static load tests to a simple box girder and large gantry crane testing, which is mainly composed of a main beam, an upper cross beam, a lower cross beam, a collar beam, a sleeper beam, a draw rod, a support stand and a lift cylinder, all the elements utilize steel box girder structure except for the draw rod, the support stand and the lift cylinder, wherein the main beam is produced in three sections, both the connection between the main beam and the upper cross beam and the connection of the main beam use high strength bolts, the upper cross beam and the lower cross beam are connected by the draw rod, and the collar beam and the main beam is connected by common bolts. When a box girder is in static load, a reaction structure is utilized to reduce the requirement for ground bearing capacity, and all elements of the multifunctional testing stand need using. When gantry crane is in testing time, only the upper cross beam, the lower cross beam, the draw rod and the support stand are used, and a hanger rod pf the gantry crane is connected with the upper cross beam. The multifunctional testing stand has simple and reasonable structure, safety, reliability and complete functions.
