These are various types of movable bridge systems used around the globe like drawbridge, folding bridge, curling bridge etc. This is because towers should be at least 18m taller than required vertical space due to machineries and rope connection and as the height of towers increase the influence of wind load increases and consequently the construction cost rockets disproportionately. A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring. The weight of the bridge is proportional to the length, the torque quickly becomes problematic as the length extends, thus it is better to have 2 opposing drawbridges than a single twice as long. The drawbridge, or bascule, is the best known; it may be single- or double-leafed. Movable bridges are the bridges which can change their position and sometimes even the shapes so as to allow the passage of vessels and boats in the waterway. Any damages of these components due to differential temperature or wearing on the alignment components will lead to improper seating of the bridge, and consequently, the leaves will jump up and down under traffic which is not desirable. Cable reels may see limited use for standard crane applications but can provide the right electrification method for special applications in tough environmentsboth indoor and outdoor. Drawbridges are movable bridges that can be found in many locations throughout the world. Can be run indoors or outdoors in dusty, dirty, or corrosive environments, in high-temperature environments, and can be used for applications that require an explosion proof design.
