ABSTRACT:
A robotic carriage for measuring the camber of a large-span structural beam is provided. The carriage includes a frame having a platform supported by a plurality of legs having wheels rotatably mounted at the ends of the legs. The legs elevate the platform above vertically extending obstacles, such as shear studs, which are frequently present on the upper surface of large-span structural beams. The width-wise distance between the legs is adjustable so that the legs avoid contact with the shear studs while the carriage traverses the beam. The carriage includes a guide mechanism formed from a pair of opposing guide members moveably mounted on the frame into sliding engagement with opposing portions of the beam to maintain the carriage on a straight path. In operation, a surveying target is mounted on the top of the frame, and the carriage is moved into selected positions at known distance along the length of the structural beam. A laser-operated surveying apparatus measures the height of the prism at the selected points so that the camber of the beam may be calculated.
