Abstract
A laser-controlled truss screed apparatus with a laser, a mover, a truss assembly, and first and second receivers. The truss assembly includes a screed, a trolley, a truss, legs, and first and second vertical posts. The receivers are configured to receive a signal from the laser. The mover is disposed on a first end of the truss, and the legs are disposed on a second end of the truss. The vertical posts, the trolley, and the screed are configured to form a single unit that travels back and forth along the truss. The legs are configured to raise and lower while maintaining a position of the truss relative to the wheels.
