Autoquip Single Leaf Bascule Bridges are hydraulically operated and can be raised to full vertical position when not in use, eliminating the possibility of interference with rail or other traffic. Single Leaf Bascule Bridges are available with crossover capacities to 60,000 pounds and platform leaf sizes to 8' wide by 20' long. Heavy-duty hydraulic cylinders assure safe and reliable bridge operation. The self-contained power unit with weatherproof cover is usually mounted on a shelf under the bridge, and easy-to-use wall-mount pushbutton controls are standard.
