An overhead line crossing guard system for guarding an asset 102 crossed by an overhead line 104 comprises a first support means 106 coupled to a first screw piling foundation pile system 112, a second support means 108 coupled to a second screw piling foundation pile system 114, and a guard means 110 connected between and supported by the first and second support means to guard the asset. The first and second foundation pile systems are adapted to be screwed into the ground on each side of the asset to anchor the first and second support means. The use of screw piling foundations means that less land area is required, and the system can be made from a small number of prefabricated parts. |
