Festoon electrification systemsare most commonly found on bridge cranes, but can also be used on othertypes of overhead craneslikegantry cranes, some forms of monorail cranes, andjib cranes. The Romans utilized numerous arch bridges for their roads because it was a simple way to increase the reach of their transportation networks. A bascules bridge is also referred to as a drawbridge (moveable bridge) with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. The swing bridge moves horizontally around vertical axis unlike other bridges which move vertically. This type of bridge runs a length of between 150 meters to 500 meters. Once the load is lifted, the push button pendant or radio remote control are used to drive the bridge crane to its destination and lower the load. They can also be used for below-the-hook devices requiring electrification. Beam bridges have a top edge that is stronger because loads are usually applied in the underside of the beam that is stretched and always under tension. These upright ties attempt to flatten the arch and transfer the load into the abutments. It is a technology that has been known for potentially 3,500 years. Utilization of this bridge stops the road traffic so that it's open for river traffic. Conductor bars are also the perfect solution for continuation of power ininterlocking crane systems.
