A temporary brace cart features a frame, a plurality of wheels for moving the frame, a bracket for coupling the frame to a vehicle (e.g., boom lift or other machine), a hoist extending vertically from the frame, a hoist arm extending from the hoist, and a winch coupled to the end of the hoist arm. In some uses, a plurality of temporary braces are positioned longitudinally along the frame for transport. A boom lift or other machine tows the cart to the desired location. Once at position, a cable may extend from the winch to a temporary brace. The winch may then be actuated so as to raise one end of the temporary brace, where it may be held until secured to the wall and ground by a worker.
