Emergency bridge and method of deployment
A temporary bridge comprises a deck 102, a first anchor 116 on one side of a space 120 and a second anchor 122 on the other and a pair of flexible supports 110, such as cables or wires, extending between the anchors and having first and second end portions 112, 114. A first abutment surface 106 is fixedly mounted to the first end portion, allowing the flexible supports to move relative to the first abutment surface. A second abutment surface 108 is fixed to the second end portion of the supports. A plurality of bridge elements 104 are mounted on the flexible supports between the abutment surfaces. In use, the tension (arrows 132) in the flexible supports is greater between the abutment surfaces than the tension (arrow 134) between the second abutment surface and the second anchor, imparting a compressive force between adjacent bridge elements and the abutment surfaces. A method of deploying a bridge may include the step of tensioning flexible supports using a winch, jack or turnbuckle. A kit of parts for a temporary bridge comprises flexible supports, bridge elements and first and second abutment surfaces.
