Straddlecarrier is used in hoisting, transporting and loading of box beam which iswithin 900t for high-speed railway in the precast yard .It travels in a wheeltire way, and its entire machine traveling, steering and lifting are propelledby hydraulic pressure so as to meet many traveling modes such as vertical,sloping and horizontal movement, which can realize all the transportation ofbox beam tasks in the precast yard. Its advantages: strong adaptability, highworking efficiency, and smaller occupying space, in addition, traveling trackneeds not to be paved in the precast yard.
According to different designed structures,there are wheel girder elevators with single beam and single portal frame, withsingle beam and double portal frame, with double beam and double portal frame.
