2024年8月7日 · Swing bridges operate through a combination of mechanical ingenuity and precise engineering. At the heart of their functionality is the pivot mechanism, which allows the bridge to rotate horizontally. This pivot is typically supported by a robust central pier, designed to bear the weight of the bridge as it swings open and closed.
2024年10月22日 · Swing Bridges. Swing bridges rotate horizontally around a central pivot point, opening and closing like a gate. This design is advantageous in wide waterways, providing clear passage without vertical movement. The hydraulic system is responsible for the rotational motion, utilizing motors for smooth and controlled movement.
There is also a wide variety of swing bridge systems. The swing bridge shown in Figure 2 is a symmetrical steel and concrete bridge mounted on a kingpost. The drive is transmitted via four single-acting cylinders working in opposed pair. An alternative is a drive via an oil hydraulic motor and a gearbox or a direct hydraulic drive without extra ...
safer compare with partial opening of vertical lift bridge and swing bridge, especially if the bascule bridge is double leaf. Whether fully or partially opened, most of bascule superstructure bridge is out of vessel
2017年12月24日 · BRIDGE OPERATION The bridge control tower houses the operator's control console and associated Programmable Controller (PC) (Fi g ure 3 .) These controls provide an orderly opening and closing of t e bridge, as well as handling the proper disposition of road and foot traffic before opening and after closing.
Hydraulic power, use of pressurized fluid to perform work, is well suited for operation of large mechanisms such as movable bridges. Hydraulic systems provide the mechanical advantage required to move the large masses of swing, vertical lift, …
What is a Hydraulic Bridge? A hydraulic bridge, called a “moving bridge,” spans water to connect two land masses on opposite sides. In a nutshell, it can be relocated to make way for ships and boats. The design of the bridge has a built-in hydraulic system so that it can support greater loads.
Development of new bearing concepts combined with hydraulic systems have led to more elegant designs of bascule bridges and swing bridges compared to older bridges, in which swing bridges were equipped with multiple wheels running on a circular rail and the rotation driven by gears and toothed wheels operated with the help of electrical motors.
2020年7月15日 · Swing Bridge: Swing-bridge is fixed on the horizontal plane that turns around the vertical axis to give way for the water traffic and the bearing is installed on a pivotal pier which is a normal pier. The ends of the span of this bridge rest on the abutments when the water traffic is …
The center pivot shaft provides vertical and horizontal support during the swinging operation. A hydraulic lift/turn cylinder allows the torque to transmit to turn and lower the structure on bearings for the railway service situation. The pivot shaft is free from loads under service conditions.
