The invention relates to a pre-tensioning method plate-beam track movable type steel transverse beam integer tensioning device and a tensioning technology. The pre-tensioning method plate-beam rail movable type steel transverse beam integer tensioning device comprises a tensioning end fixing steel transverse beam, an anchoring end fixing steel transverse beam, steel strands, beam restraining table bases arranged between the tensioning end fix fixing steel transverse beam and the anchoring end fixing steel transverse beam, a force transmission column arranged on one side of each beam restraining table base, a track movable type platform arranged on one side of the tensioning end fix fixing steel transverse beam and up-and down adjusting steel plates, wherein the up-and-down steel plates are connected on the tensioning end fixing steel transverse beam, the anchoring end fixing steel transverse beam and a lifting jack moving transverse beam in a buckling mode, and each steel strand is provided with two dual-connecting elements, a single connecting element and three sections of precision rolling twisted steel bars. The pre-tensioning method plate-beam track movable type steel transverse beam integer tensioning device is further provided with a pre-tensioning plate lifting device. The pre-tensioning method plate-beam track movable type steel transverse beam integer tensioning device can conduct construction on multiple beams simultaneously, saves materials, is safe, reliable, capable of being used in multiple times, suitable for construction of all bridge types, simple in operation, continuous in construction and suitable for construction of all beam-plate types, and improves effects. The pre-tensioning plate lifting device is capable of rotating at 360 degrees, storage of movable beams is convenient, occupation of a crane is reduced, and efficiency is improved.
