The utility model discloses a can cross mound formula bridge check -out set, include: examine the car platform for a work platform that when inspection or maintenance bridge is provided, transverse guide sets up on the bridge along bridge length direction, walk the cross girders support, walk the first end of cross girders support and can dismantle the connection on transverse guide, the main structure truss includes: longitudinal rail, rotation mechanism and main structure truss framework, the longitudinal rail sets up in main structure truss framework along the direction of height, rotation mechanism sets up on the top of main structure truss framework, and rotation mechanism is connected with the second end of walking the cross girders support for gyration through rotation mechanism makes to be examined the car platform and keeps away from or be close the pier. Examining the arbitrary maintenace point that the car platform can remove the bridge at any time like this, not receiving the space limitation of pier stud, the move mode is nimble. Walk the dual support of cross girders support and main structure truss, support the reinforce, can promote the bridge by a wide margin and examine and repair the operating efficiency.
