The advantages of the cable-stayed bridges include: The cable stewed bridges also have some disadvantages such as: Cantilever bridges get their name from cantilevers, which are a long beam that has only been fixed at one end and the second end is free. A dental implant can offer natural-looking and long lasting results, but they tend to be more expensive than other treatment options. Another component of a bridge is the bearing. Mainline conductors rigid construction bars, cable festoon system, or cable reel that delivers the mainline power along a runway or monorail track, Bridge conductors electrical conductors located along the bridge structure of a crane to provide power to the trolley and hoist, Runway conductors main conductors mounted on, or parallel to, the runway which supplies current to the crane, Enclosed conductors a conductor or group of conductors substantially enclosed to prevent accidental contact. Corrections? There are some applications where the conductor bar may not be insulated, but the most common types have insulated covers. Omissions? Cable-stayed bridges do not possess any anchorages that put up with the compression, and it only just a single tower to bear the compression. This is because the truss is progressively deeper as one reaches mid-span.
